ビジュアルエフェクトが楽しい理由の 1 つは、現実には何も破壊せずに、さまざまなものを爆破できることです。 このレッスンでは、パーティクルの火花を使用して導火線に火を付け、カートゥーンの爆弾を爆発させます。 爆弾にはリジッドボディダイナミクス、火と煙には Pyro FX を使用します。このレッスンでは、さまざまなシェルフツールやネットワークノードを使用して、ダイナミックシミュレーションをセットアップする方法を学びます.

作成するショットを完全に理解するために、すべての要素をゼロから作成して、エフェクトをシミュレートします。 Houdini シーンのさまざまなコンテキストで、シミュレーションノードがどう機能するかを理解しやすくなるはずです。最後に、Karma レンダラを使用してショットをレンダリングします。

    Hi, i need some help, if i click polybevel in houdini, it shows fatal error and get crash. What is the solution for this problem

    • jjin10688 1 年 前  | 

      It might be because your pc doesn't use high detail if it is not a high-end PC.

  • spyco59 1 年, 8 ヶ月 前  | 

    Thanks Robert! Really appreciate having a PDF file to follow along! :)

  • luoyuepo 1 年, 7 ヶ月 前  | 

    And there is something wrong with the PDF file.

    On the Page 21, paragraph 2. The expression should be
    “ Set the Prune parameter to
    $F >200. After the expoding_bomb node, add another Prune LOP.
    Set the Prune parameter to $F <199."

    I did just just like the PDF said,and the bomb became invisible all along in the timeline.

    Hope you can fix this soon.And thank you for all the nice tutorials!

      I had the same problem and solved it with this:

      prune>primitive pattern>input last modified primitives

    Hi! I noticed the orient along curve works while we are on the construction plane (from 0-142) but at frame 143 when the cap starts rising up toward the bomb, it gets slightly off from the poly wire. It's close but not exactly on. Why is this?

  • JoeRan 1 年, 1 ヶ月 前  | 

    Unfortunately I'm stuck in the last step (number 11 - Render pyro fx)
    Despite having 40 GB of RAM on the PC, the computer does not hold up!
    Crash at the exact moment I enter the pyro effect usd.

      Did you change the start frame to 200 and the Frame Range to 200-240? - Part 8 steps 1 and 2

  • Dohesh 11 ヶ月, 1 週間 前  | 

    my file is exporting in usdnc how can i save in USD

    • shung1021 11 ヶ月, 1 週間 前  | 

      when you try to bring in the USD in the reference node, there should be a drop down menu on the lower right hand corner that says "*.usd, *usda.... etc.," change that to just "*" and you should be able to see your USDNC files

      • Dohesh 11 ヶ月, 1 週間 前  | 

        i also tried this method and its showing usdnc files but there is 1 error and the error is
        "Unable to find layer file: 1/Houdini/Destructtion"

      • AbhishekDhiman 10 ヶ月, 3 週間 前  | 

        Thank you

    • shung1021 11 ヶ月, 1 週間 前  | 

      i assume the NC in USDNC simply means Non Commercial

    Thank you so much for this tutorial Robert! This tutorial helped me so much in getting started in Houdini!

    Hi, I got an error when selecting Simple Fracture for the bomb. The network nodes are created but there's an error saying:
    "Error: Invalid source/obj/bomb_geo_fracture/rbdmaterialfracture/init_opencl"
    Anybody has an idea what's happening?
    Thanks a lot

  • enzo.nhr 7 ヶ月, 3 週間 前  | 

    My popnet create particules in the wrong direction, as if the particules were created inside the sphere, not outside, which cause the soot trail to go the opposite direction it supposed to be :(

    • Kucheryat 6 ヶ月, 3 週間 前  | 

      you should try change scale-time in popnet node to about 0.20. that helped me

  • LukeP 7 ヶ月, 2 週間 前  | 

    Overall comments about this book and this training. I think it's a good example of how things should not be written and examplifies problems with Houdini documentation. For me at least. I'm sure others' opinion will be different. That doesn't mean that it wasn't useful. You can still learn Houdini from it, but it's supposed to be a Foundations book, right? Meaning that the focus should be on explaining core concepts. Something that MOEEN SAYED does really really well. Lets take tutorials in this book. There's very little explaination. Do this, set this, type this, without explainations is not helpful. Neither is going from basic concepts to some advanced ones. Again, perfect example of what needs to change wrt to Houdini documentation.

    • rmagee 7 ヶ月 前  | 

      Thanks for the feedback. The goal of this book/tutorial series was to help artists build muscle memory and learn how to accomplish day-to-day tasks as they get through their first few projects in Houdini - this will lead to questions that they can begin to explore using other learning materials. In fact, we commission Mooen to make tutorials for us to add that other layer. So in the case of this book, Foundation means getting comfortable with the software and touch as much of it as possible rather than diving into core concepts.

  • Kucheryat 6 ヶ月, 3 週間 前  | 

    Hi, i need help on step 5. Problem started after adding attribute transfer. Particles are not going in direction of the fuse. All steps before are working correctly. What should i do?

      oh, sorry, i found the problem

    Hi, I need help. When I used simple Fracture, the bomb just rolls over the ground instead of blasting.

    Hi! I had the same problem. In the rbdmaterialfracture node delete the Glue from Glue Constraint Name.

  • planimation 3 ヶ月 前  | 

    On Video 5) at 6:20 I put in the code $F >199 but my partials don't die after frame 199 anyone know what the issue is, cheers!

    • planimation 3 ヶ月 前  | 

      Solve it! i forgot to click Enable in the V Expression

    anyone know why my sparks are going through the floor? video 06?

    • planimation 3 ヶ月 前  | 

      ah found it, it's because I name my attrbadjustfloat1 to LIFE to life.

  • planimation 2 ヶ月, 2 週間 前  | 

    currently on video 11, around 3:05 once a add the prune node i put $F>200 but it doesn't work, is this because i'm using a UK keyboard not sure how to fix this please help cheers!

    • planimation 2 ヶ月, 2 週間 前  | 

      so i solve this by creating the node again

  • planimation 2 ヶ月, 2 週間 前  | 

    I got a new problem, currently on the last video and I don't see the pyro render only the dust.... what do you think happen?

  • ktjk1 2 ヶ月, 2 週間 前  | 

    I've been working my way through the Houdini basics course, but I'm stuck. When I finally render, the material library node is applying a pyro shader to the material VOP input field, but all other geomatry's materials disappear and I can't recover them. I've followed this process at least 10 times and studied the information, but I can't get it to work. Houdini is a good program, yes, but it's too unstable and finicky. It's a program that doesn't give me the same result even if I follow it exactly without missing a single moment. I don't think it's a good program in that sense. I need to find another good program.

  • Harry__243 2 ヶ月, 1 週間 前  | 

    I´ve a question. Working on Part 10, my Prune Notes don´t work (both). Does anyone has an Idea? I killed my presets, using the default but the Problem is still there.
    My Workaround, using the time-expression directly in the Primitive Count of the Reference Note works fine and delivers the expected results... but this doesn´t fix my prune issue. Does anyone has an idea (using Houdini 20.0.590 on Windows).

    • Harry__243 2 ヶ月, 1 週間 前  | 

      I´ve found the issue... the prune note defaults have been changed. In Target Primitives under Primitive Pattern I had to choose `lopinputprims(' . ' , 0)`

  • m.colonnelli 2 ヶ月 前  | 

    Fantastic tutorial. At the moment, I only have one problem that I don't know how to solve: when I switch to render view (Karma), all materials look good except for the "Soot" where the particles turn into very large spheres. Do you know how I can solve it?

  • carlosvega 1 ヶ月, 3 週間 前  | 

    Hi, i have a problem, i'm in the part 7, and when apply the simple fracture and set up the fracture solver, delete the glue, and run the simulation, the bomb rolls instead of break, like all the pieces are glued. Can anyone know how to solve it?

    • MTU1500 5 日, 16 時間 前  | 

      I had the same problem. I solved it to put the strenght on 0 in Advanced ==> Glue ==> strength.
