I am taking a tutorial from the houdini version 8 and it is asking for me to create a spare parameter but I cannot find the menu they refer too. Could someone please point out where I add the spare parameter? Thanks in advance.

Thank you all very much for the courteous responses. I think im going to continue learning them both. Ive just spent more time with blenders modelling because it feels a little more natural to me..However, I have seen some of the amazing things that houdini has produced and for what im trying to specialize in (particles and rigid/soft body dynamics), I think houdini needs just as much of my attention. Thanks again!

First off I dont intend this thread to be a VS. war by any stretch of the word. I just have a simple question in regards to known differences between Blender and houdini strictly in regards to modeling. I guess my question is this: Is houdini on par with or surpassing blender when it comes to modeling? I just wanted to know as I have been studying extensively with blender and houdini and due to the ease of modeling in blender I have neglected time learning houdini (I want to learn houdini for industry purposes). Could someone offer some unbiased advice and please no vs wars as this is not what this thread was intended for. Thank you.

Thank you Allegro. I appreciate that . I do have one quick somewhat off the wall question, but do the fluids and animation renders take as much time as particles or are the particles among the most time consuming of the effects to render? I guess this question is to anyone that knows.
It really depends on what you're doing. Shaders, lighting, how much of it is in your shot all make huge differences…
You can also render particles with metaballs attached to them which have volume shaders… so… it's tricky to give a good answer for this one.
Im sorry, I meant to say bake times. For example, I load up a fireball and press play for it to start calculating. It takes about 5-10 mins to run 120 frames. If I make almost the littlest change I have to let it bake yet AGAIN and wait another 5-10 mins. Thats what frustrates me. I mean, if I change one value by the smallest unnoticeable amount it re bakes it all. Thats going to take forever. I just hope im doing something wrong.

I think it took me about an hour to record that 19 minute video as I would pause at the same time as/just before/just after pressing the simulate button and then unpause when the simulation was done.
The plus side of doing up resing, is that the look you get will be very similar to the low-res (but better) meaning that you can do most of your iterations using the low res sim.
You can get the black background in the “display options” (press d when your mouse is in the viewport)
1.5 to 2 days does not seem like a proper time if you are trying to render out the preset. Especially not on 8 cores. It did not take that much time on my machine.
Hopefully Andrew will get a chance to look at this soon and see if anything can be done about the render speed

Hi,
The video was indeed edited for the reasons described. I've been doing a lot of work on the Pyro tools and simulated everything on a single machine, using 2 or 4 cores. Although not as fast as seen in the tutorial., it shouldn't be that bad. It does take time to create a good simulation but all the examples shown in the H10 launch videos were created on a single machine (except the high res volcano like smoke, having a resolution of 1000^3). The low res sims should take about 10 minutes to simulate (up to frame 70-100)
I tend to start on a resolution of 40 to create the general motion and expansion, and gradually pump up the resolution (to about 70) for my final low res passes. After that it's rendered to disk and ready for upressing.I never go above 250 for those
Hope that clarifies things a bit :wink:
First of all, Thank you all for your helpful responses. I didnt want to make 4 posts in a row. Cklosters, how do you change the resolution to 40? I just want to be able to test it (im currently learning fundamentals but just want to know this one particular advanced technique as particles is my main focus of visual effects). Thank you all again.

I think it could be due to editing or he already has the geometry already written out. Not fun for viewers to watch the progress bar for a few mins right?
For the black viewport, type ‘d’ in the viewport for display options, viewport tab and change “Light” to “Dark”. I don't have Houdini opened right now but you should be able to find the option easily.
Cheers!

Thank you for the help. Its much appreciated. I just wanted to make sure I wasnt doing something wrong.

He probably has cached out the files before recording the video.
Jepp and the pyro effects take ages on my computer too. Nothing for single computer users. Too bad actually.
Ah ok ic. So in other words were probably not going to be able to make good flame and smoke effects on a single computer for our own indy films? That is a bummer lol.

Hey guys, I just watched the h10 pyrofx video and was noting how fast the instructors bake times were and how they only took a manner of seconds for a pyro fx fireball. Mine are taking ages. I do understand that he is probably using production grade hardware but im using an e8400 core 2 duo and an ati 4870x2 and its just creeping. I noticed that when he runs the sim he only puts 5 seconds and after it loads the five seconds he has 120 frames worth of render for his smoke effect. Am I doing something wrong. I have mimicked his steps to a T. If I change one setting it has to rebake the whole scene so its a little disheartening to see that I will have to wait 5 mins between each change of a setting just to view that change. I would also like to know how you get a black screen behind your object when simulating particles as opposed to the stock gray (the color in the scene view box). Any help would be highly appreciated. Thank you.

You should def know what kind of file you are importanting because you exported it with Blender, right?
Try a file SOP.
No I just open up houdini and select import and it gives the error. Im not doing anything with blender.

What format are you trying to import from? An .obj or the native Blender format?
I dont even get that far tbh. I just select import then geometry and it gives me that error. Im not sure what it is.

When I try to select import and import geometry it gives me the main menu error “An error occured while executing menu python script. Could not open file…” Im not sure if this is normal or if something is wrong. I had to install a python version into my blender files tonight and this was the first time trying to import an object so im not sure if the python installation did something to the houdini app. It did bring up an error at boot for houdini but I reinstalled it as well as uninstalled the newly installed python files. Now that its reinstalled I still cant get it to import. Can someone help please? Thank you in advance.

It has no limits on import. What you want is very doable, both SynthEyes and PFTrack export Houdini scripts which can be loaded.
Enjoy!
Dragos
Very cool!!! Thank you both for your prompt replies. Its much appreciated

Hey guys, just wanting to know if its possible to use matchmoving software with houdini to make a demo reel? Do I have to have the full version in order to use a seperate matchmoving software such as PFTrack, Syntheyes, or Voodoo? Thank you in advance!
Hairston
You can use Apprentice with all of above tools (don't know how voodoo works with H. though). Apprentice doesn't have any limitation on import side, and this is what you need to do it, right?
hth,
skk.
Yes, that is correct. Im wanting to be able to put my 3d models from houdini into the live action film using a matchmoving software. I was afraid that houdini would not allow you to do that in the apprentice version but from what you said it seems that I can. Thats great!
