TOTAL DURATION: 1h 8m 23s

In this lesson, you will take your first steps into Houdini as you model a coffee cup then use dynamics to simulate a collection of gumballs falling into it. You will apply textures and materials, add lights and a camera then render out the finished sequence. By touching all aspects of this shot, you will begin learning how to navigate your way through Houdini and its node-based workflow.

This lesson includes a Step by Step PDF document to help guide you.

    This is a great set of beginner lessons. I like how it covers all the newer features like solaris and copernicus.

  • knockflakes 11 months, 1 week ago  | 

    Thänx a lot for this great tutorial! So many useful tipps!

  • PerpetualZest 11 months, 1 week ago  | 

    Just leaving this comment in case someone has a similar issue. I had an issue with shadows not displaying in the viewer in Solaris (Video #4). I realized that I only had "Full Lighting" enabled, but I needed the next button down, "Full Lighting with Shadows" to be enabled instead. They are small buttons on the right side of the viewer that look like a lightbulb with a "+" sign inside.

    Anyway, thanks for posting this series, I'm enjoying learning from it so far.

    • dinhphat255 6 months ago  | 

      bro thanks alot I have the same problem

  • LuzidVision 11 months, 1 week ago  | 

    Just as PerpetualZest said, to have the cup cast shadows on the ground in the viewport render, go to
    Scene view -> Display Options -> Lights Tab -> Lighting Quality: Full Lighting with Shadows

  • piumal89001 11 months, 1 week ago  | 

    perfect tutorial.really good for beginners.❤️

  • ertemi 11 months ago  | 

    This is truly the best tutorial I have seen so far.
    You can see the effort put into explaining every detail.
    Thanks to Mr. ROBERT MAGEE

    does anyone know how to solve this error from video 6?

    "Unable to find layer file: 20.5.278/projects/overview_lesson/usd/gumball_sim.usd"

    "Targeted missing explicit primitive: /gumball_sim"

    the error is at the reference node

    • johnkozikowski 3 months, 3 weeks ago  | 

      is it a .usdnc because you don't have a commercial licence? the nc means nothing, just "non commercial"

  • johntdp 10 months, 4 weeks ago  | 

    I got stuck in Chapter 3. Can’t get Copy to Points to work. I have nothing selected, click Copy to Points. I get the prompt to select the first object. I click on the node for the sphere and hit enter, but then do not get the second prompt to select the box. Instead it just opens up the sphere node. What am I doing wrong? Thanks!

    • chretien 10 months, 3 weeks ago  | 

      I got the same issue, I solved it by placing my cursor to the viewport panel instead of having it in the goemetry panel.
      Hope it helps.

      • chretien 10 months, 3 weeks ago  | 

        to clarify, after clicking copy to point and selecting the sphere before you hit enter move your cursor to the viewport panel not the node/geometry panel.. hope it clearer

      • vstevenson 10 months, 3 weeks ago  | 

        This is rarely ever mentioned in even the most fundamental beginner tutorials. I can count on my hand the number of times I've heard a presenter mention it having watched literally 100s of Houdini videos over the years. Thank you for taking your time to mention this very important note for new users.

      • sebABF 3 months, 3 weeks ago  | 

        Thank you! I just got stuck here with the same problem.

  • pierrx666 10 months, 3 weeks ago  | 

    in chapter 5
    at the reference nod creation
    at file pattern windows
    I had to select the all files sign in the drop menu bottom right (the little star : only *)
    because my usd file saved in the step just before is a .usdnc instead of a .usd as shown in the video
    I was stuck here for 1 hour retrying the steps many times before I found this.
    is it normal ?

    • Vin20 9 months, 2 weeks ago  | 

      Yes it happened to me as well, thanks for the help, after clicking on the file, I also had to click the little box that said make path relative to current Directory

  • remlapeel 10 months, 1 week ago  | 

    Good at points, but clicks without explaining a lot, and like a lot of tutorials is tell you what to click and not why.

  • Eddie_Roach 10 months ago  | 

    When I import my cup into solaris stage it returns to default. It loses the handle, the subdivisions, etc. Also the ground geo doesn't sit within the geo drop down of the scene grpah path after merging it with the cup geo.

    • Eddie_Roach 9 months, 4 weeks ago  | 

      Looks like I had to change SOP Import Mode to "Display". I now can't seem to get any shadows on the ground geo when I add the point lights.

      • MataS9 9 months, 1 week ago  | 

        How did you change the SOP Import mode?
        BTW you have to use the buttons on the right of the viewport and select the one that has a lightbulb and a black hole thing under it to have shadows. good luck!

  • cruzdh2035 9 months, 3 weeks ago  | 

    In chapter 6 when I click "File Pattern" to import the balls to the stage, the file gumballs_sim.usd doesn´t appear. I hope someone can help me with this problem :(

    • rmagee 9 months, 3 weeks ago  | 

      Are you using apprentice? Then you need usdnc. If that is not it then choose usd from the menu next to the file name.

      • cruzdh2035 9 months, 3 weeks ago  | 

        It worked, thank you so much :)

      • Laura-89 6 months, 2 weeks ago  | 

        I need help. I'm using Houdini Apprentice. I'm currently on chapter 6 trying to add file pattern. When I click on USD and see gumball_sim, it's got a folder logo next to it instead of a paper logo. When I click on it, there's nothing there. I am unsure of what to do?

        • Laura-89 6 months, 2 weeks ago  | 

          Don't worry I figured it out :) However, I just pressed play on the animation and the gumballs are going through the floor :/ lol. What have I done wrong??

    Hello All,
    I have done this tutorial 3 times now and I keep getting the same error on part 6 step 8. After I click render to disk I get a red triangle with the errors:

    "failed to create file "C:/Users/virid/AppData/Local/Temp/houdini_temp/usd_renders/usdrender_2756_1256_1/bump_normal.1.exr : No such file or directory"

    I'm stuck editing the material properties. It doesn't have the same color options as the instructor's material. When I searched for "quick," nothing came up, so I had to look under "material" instead. I was hoping to catch up on the first day of the Mardini contest, but it looks like I have a long way to go. :(

  • ale85 7 months, 4 weeks ago  | 

    Hello, I have a problem, in Solaris when I set the metalness to 0.8 in the gumballs material and render it, the render is like full of little white dots on the balls and it goes away just if I reduce the metalness to 0.3 or lower. It's not the first time it happens and I have no idea how to solve it, I tried everything. Any help?
    Thank you

    I cant find the quick material in the tap in solarias any help ?

    • rmagee 7 months, 2 weeks ago  | 

      Is your mouse over the network? It won't work if your mouse is over the viewport - Also you need to make sure you are at /stage which is a Solaris network.

  • canislupus 7 months, 2 weeks ago  | 

    Hi, I'm stuck. Nothing appears to me about the "quick material". I tried to get a houdini indie license but I think that didn't help at all. I need help.

    • canislupus 7 months, 2 weeks ago  | 

      Ok, I fixed it by putting in an Edit Material Properties but I don't get the options to change the color or anything like that. Now I don't get anything out of the COP Network, I can't edit the floor. Do I have to buy or download something specific so that these nodes come out?

  • KTTC 7 months ago  | 

    Hi all, im new to Houdini and this is a great tutorial however im having issue of some gumballs going through the cup, anyone know how to fix this or might be causing this?
    Im wondering if i didnt do something right possibly during copytopoints?
    TIA

    • rmagee 7 months ago  | 

      If this is happening at the end of the lesson it is possible that you didn't recache the simulation so the simulation is working with the smaller cut instead of the taller one.

  • viraj_dey 5 months, 2 weeks ago  | 

    Please need assistance. Having problem with Lesson 3, I made the Sphere and the Box objects, now at Object Level with nothing selected, I select Copy to Points, but when I select the Sphere and press Enter, it takes me to the Geometry Level of the Sphere, same when I select the Box. I tried selecting both Sphere and Box together and then pressing Enter but it takes me to the Geometry Level. Copy to Points isn't working for me. What do I do? I'm new to Houdini and using Houdini Apprentice.

    • viraj_dey 5 months, 2 weeks ago  | 

      Problem solved.

    Help!!! Lesson 6, I did everything right, but when I Render to Disk using usdrender_rop, it doesn't render, it finishes before 72 frames, so far I could only render 1-3 frames when I checked in MPlay, Load Image tab. I am using Houdini Apprentice and lowered render resolution to 1280x720, still does not render. There is a error red triangle with an exclamation mark on usdrender_rop, inside node info it says:
    Failed to complete render: exit code -1073741571
    Use a Log Viewer with External Render Processes enabled for more information.

      I would suggest touching base with support - sounds like a technical issue.

  • gamaod 5 months, 1 week ago  | 

    Hi,
    I am on Part Six, step 01. When I Save To Disk, it saves the file as $HIP/usd/gumball_sim.usdnc. i have no idea where the nc at the end comes from. I can select it after I remove the nc at the end, but when I get to Step 02 nothing shows up in the Scene Graph Path panel in the bottom left. Up to this point I have had no problems with the tutorial, so what did I do wrong?

    • rmagee 5 months, 1 week ago  | 

      It is because you are using Apprentice or the Education version of Houdini. Instead of removing the nc - set the "Show files matching" list to * when you load the file. This should make the file available for selection.

  • Marco1110 3 months, 2 weeks ago  | 

    If anyone like me had an issue with the balls not colliding with the cup, you need to plug in the object merge node in the 3rd pin of the rbdbulletsolver node rather than in the 4rth pin

    • rmagee 3 months, 2 weeks ago  | 

      It should be the fourth - that is the collision input

      • Marco1110 3 months, 2 weeks ago  | 

        I double checked and you're absolutely right. I've initially plugged it into the 5th pin thinking it was the 4th cause I didn't realise this node had 5 pins

  • brad-NBO 3 months, 1 week ago  | 

    I have a question in chapter 3 regarding the Convex Collision Shape for the cup.

    The gumballs, the first half of them just pass through the bottom and sides of the cup rolling on the ground. The remaining stay in the cup and stack up and overflow as expected.

    I've tweaked as many parameters as I could and even tried rearrange the order of the nodes to see what that would do but nothing changed the behavior.

    Any suggestions what it may be that is causing this? I tried all the other collision shapes and they seem to work as expected. I am using the latest Apprentice version since a couple of days ago, 20.5.613.

    Thanks, love the tutorial and Houdini, it's awesome

    • brad-NBO 3 months, 1 week ago  | 

      I was trying to add more objects and added a RBD Bullet Solver node for each object. The sim doesn't like it, it partially works. There must be a way to have multiple objects in the scene for a sim, eventually I'll find it. Individually the objects work perfectly but the way I added multiple RBD Bullet Solvers tied into the Merge Display didn't work as expected.

  • johan.axdorph 3 months, 1 week ago  | 

    Got stuck at chapter 2 at 01:25. He sets the Justify Z to "None" in order to center the cup in the Match size node, but when I set it to none nothing happens at all. "Min" and "Max" makes it move but "None" does nothing. Does anyone know why?

    • johan.axdorph 3 months, 1 week ago  | 

      I solved it. Had to put Justify X to "none" instead of Justify Z.

  • brad-NBO 3 months, 1 week ago  | 

    In chapter 4 I find the Karma XPU leaves a pixelized outline around objects and the denoise doesn't get rid of it.
    But the Karma CPU functions well. Not sure if using the CPU makes much difference than the XPU. I'm using a laptop NVIDIA 3070 with 6gb vram so maybe that may be a limitation for future considerations?

  • blorgbyr 2 months, 3 weeks ago  | 

    Just finished the whole thing and it was amazing! Only question is any idea why my renders are 1280x720 resolution even though in the render settings they´re set to 1920 x 1080?

    • blorgbyr 2 months, 3 weeks ago  | 

      Might be a license issue now that I think of it.

  • emilytrantow98 2 months, 2 weeks ago  | 

    Great intro to Houdini! Modeling the coffee cup and then adding the gumball dynamics is a fantastic way to learn the node-based workflow. This reminds me of the procedural generation possibilities in games, specifically thinking about procedural map creation like in Pokerogue, and how a detailed Pokerogue Dex could benefit from similar data management. I appreciate the PDF guide for beginners! https://playpokerogue.com

    • badbunny 1 month, 4 weeks ago  | 

      Hi, I've got the same problem. This is my second run through of this lesson. In the first run through it worked, but this second run through it doesn't. I've updated Houdini since the first run through about a month ago. I assumed it must have been something I did wrong, so loaded my first project to see if I could see the difference. However it is also now not working. So I'm assuming something has changed in Houdini that requires an additional step, but haven't managed to figure out how to fix this yet.

    • badbunny 1 month, 4 weeks ago  | 

      I just tried downloading the latest 20.5 production version which I must have had previously and it works ok in that version. So definitely is something that has changed in 21.0. Suggest downloading 20.5 through the launcher (can install multiple versions) to do this lesson until someone posts how to fix this.

    • michael_cab 1 month ago  | 

      Hello!

      Im also encountering a similar issue.

      On lesson 5 (texturing the ground) at the 2:00 minute mark. I created the COP node and changed the color, but I am unable to see any change to the UV scale via the UV scale parameter in the Quick Surface Material for the ground. I am using Houdini Indi 21.0.440.

  • florian.barbera 1 month, 3 weeks ago  | 

    Hello ! Great tutorial. I'm learning with Houdini Inidie 21 on a Linux Ubuntu Sturdio 24.04. Chapter 4 : I have an error adding the quick surface material :

  • VectorBelmont 1 month ago  | 

    Ok.... So... to anyone who is doing this tutorial in more recent times. It is currently October of 2025. When you create geometery. This new type of node is added in.

    Not accounting for it jams up your results often during these tutorials.

    If you create "box1". There will be attached between it and your intended next node a node called "box_object1_xform1".

    I'm still super new to the software, but after figuring this out the tutorials went from "Conversation with the Cheshire cat" into: " Coherent understandable experience."
    Eyes open ya'll.

      Just in case someone struggle with it, I solved by going in the geometry level of the gumballs and activating the "eye" icon for the Bullet node. After doing that, I returned to object level and the balls were appearing correctly, with simulation running as well.

    hello, my cup is not centered anymore (which should have been the case for you aswell) and when i create the sphere they're not aligned, how do i re-center the cup?

    • rmagee 2 weeks, 3 days ago  | 

      On the Match Size node, set Justify X and Z to None

          Check the object level - the transform values should be 0, 0, 0

    If anybody else cannot see the weight colors of the Soft Transform in Chapter 2, press D while in the viewport > go to the Visualize tab and enable Soft Falloff under Common Visualizers.

    Hi there. Great series of tutorials. Many, many thanks!
    Chapter 5. I'm trying to texture the ground, but can't adjust tiles to my liking; they are way too big.
    The pattern is not changing when the UV scale is increased in the ground mat node in Solaris. The size of tiles does not change. When I'm trying to adjust a tile pattern node in the COP network, I get a wide edge between tiles, which is not right.
    I just want a smaller overall pattern without wide edges.

      It is hard to figure out your issue without seeing your file. Please share.

    hey great job btw but i want to ask you a question in houdini 21 in chapter 5 when i change the number of uv scale in maps i do nothing ! i cant see the changes in the viewpoint why if i can ask ?

      I just tested it and it works for me. Maybe restart the rendering using the same menu where you chose Karma XPU

        when i change the numbering inside the cop network it made the changes but when i change inside the edit material properties it did nothing and i guess it is about the op: in houdini 21 !

          See the image above where I answered the same question for t0mb3r. It works on the ground_mat node for me. Maybeo get the latest production build of H21?

    h21 is so incredibly buggy

    If I always want Pack and Instance to be checked, why is it not checked by default...

    in the lookdev part i dont have a shadow even tho i followed strictly... really maybe just do the tutorial yourself with a fresh houdini 21 and see where it breaks

      ok so you gotta check "shadows" under the scene lights option (the light bulb icon) in the display options bar (the left bar of icons in the viewport). Wouldve been nice mentioning.

    when creating the very firsts cop network nothing changes in the viewport in contrast to the tutorial, where the checkerboard pattern becomes partly purple
