I did what you suggested and it seemed to work. Have no clue either because nothing was keyframed. But works great now

I tried attaching a camera to a path, using the circle spline and it works, except around frame 135 their is a weird wobble where the camera jumps.
I can't seem to figure out why it is doing this. Guessing maybe something in the circle properties, but not sure.
Attached is the file

Oh, there it is. I was looking on the V-litfog in the shop network and couldn't find a render tab.
ok, that makes sense. Thank you everyone for the help!

is there any type of Grid Overly options in houdini to do something like rule of thirds for alignment in the camera view?

Hi,
Sorry, I forgot all about this post. And came back and noticed their were some replies. I created a sample scene to explain the issue so you understand the issue with volumetrics
The problem is that the v_litfog affects all lights in the scene. But in this scene, I want the spotlight to have volumetrics, and the backlight to affect all geometry, but not the v_litfog shader so you don't have that weird circuler back glow which doesn't look right
Attached is a scene file and pic so you understand

Well, it still does not work for me, but the error changed.
And no longer get this “CreateProcess failed for ‘prman'”
Attached is what it looks like now

I don't know, I went through all that. And many other posts. What works for some, doesn't seem to work for others.
But I can't seem to find a simple official documentation by Pixar stating the setup procedures.
It's very strange and doesn't seem that complex to do. Set up other renderers using the environment file and haven't had any problems

I see a lot of people seem to have the same problem, but I don't see much answers to the problem
I am trying to set up the Non Commercial Version of Renderman 20 to try with houdini. This is what I have done.
First, I set a windows environment variable under Path=C:\Program Files\Pixar\RenderManProServer-20.11\
Then I went into Houdini, under Edit/Preferences/Render and checked Renderman 20
I then modified the houdini.env
With these lines
RMANTREE=“CProgram Files/Pixar/RenderManProServer-20.11”
PATH=$PATH;$RMANTREE/bin
HOUDINI_DEFAULT_RIB_RENDERER=prman20.11
When I go to render, I get an error
CreateProcess failed for ‘prman’
If anyone knows the setup procedure, or what I am doing wrong. This would be helpful

Hi,
Thanks for that. That seems to have answered my question. Although didn't solve my problem.
The problem I am having is that I have a scene with a spotlight and the VlitFog for volumetrics. I also have another back light in the scene. The problem is that the backlight creates effects I don't want and I need to figure out how to tell the backlight not to affect or exclude the volumetrics, the spotlight with the vlitfog attached.
The light linker seems to only list objects. If anyone knows of a solution for that, that would be helpful

Houdini Learning Materials » Color Vertex model import colors look different in Houdini and trying to figure out how to adjust them correctly
- vertigo262

On doing some tests, and bringing the model into 3d Studio It appears to have the same problem. So I think the issue might be the 3D coat export and the paint room layers. Although I would still like to figure out how to do other things like adding vertex color to displace and things like this.

Hi,
I am doing some experiments from 3D coat to Houdini using vertex color information on high resolution models instead of using texture maps.
it seems to work pretty well, but when rendering in Houdini, it doesn't represent some of the color information I see in 3D coat.
The things like dirt and rust don't seem to work very well. I noticed this also happens in other programs as well. So far, I figured out some mods to the shader to enhance the vertex color but I don't see a lot of options in houdini. Or I just don't know them as I am fairly new to houdini.
Also I am trying to figure out how to do things like pipe the vertex color into the displacement and such which I figured out how to do in some other programs
Attached are some screen shots to see what I am talking about.
If anyone knows how to get the vertex color information closer to the original. That would be very helpful

Houdini Learning Materials » Layering a 2nd shader for a decal

I have a shader already using a texture, and I am trying to add a 2nd layered shader using alpha to use a decal.
I got as far as setting up the 2nd layered shader with a decal, and that works, but the problem I am having is trying to figure out how to set it up so I can position and scale the 2nd shader image.
I have the UVcoords1 going to both the alpha, and the shader texture, but from there, I can't figure out what to do to put the correct node that works.
I tried UV transform and UV postion linked off the uvcoord1 but it didn't work.
hoping someone knows how to do this correctly

Welp, this was very helpful, I thank you very much.
I think I spent about 15 hours researching and trying to figure this out and I wasn't anywhere close to figuring out a thing.
It turned out to be a lot more complex then I thought it would be. I figured you could do it with the Sops, and no need for expressions.
I am new to Houdini, and I really liking it, but this very complex for a beginner. But it was what I needed and worked out great.
Still trying to absorb the vastness of Houdini, but slowly figuring things out
Thank you very much for showing me how to do this

I have a simple location particle emitter, and I managed to figure out how to attach an object to the particles. But I want to attach multiple objects to the same emitter randomly associating the objects with the particles.
In this file I have an emitter, a box, and a torus. I can either attach one or the other. But I can't for the life of me figure out how to do both.
Help appreciated
