In Houdini 20.5, when creating a cliff-like detail with volume vop, I want to control the unified noise applied in the Y direction with ramp, but I don't know how to do it. If anyone knows how to do this, please let me know. I want to control the effect of noise on this video in the Y directi... -
Hi everyone, I have a velocity volume working well to advect a vellum sim, by pulling the objects towards the normals of an object. However I'd like to remove all velocity values from within the object, so that once they've been pulled in and "captured", that they can then move fre...

Hello, people of OD force, I am a noob at Houdini only a year of experience with the software but I am having fun and enjoy learning it. Now I am doing a short film for university and I made a few different effects. I have accomplished the effects I wanted but the problem is I cannot seem to be...

Hello all, I know how to displace a surface, using the volume vop. VDB workflow. The displacement is generated by noise within the volume VOP. What I am trying to figure out now is how to have the displacement only on certain parts of the surface, only on certain parts of a sphere, for exa...

Hi, I am trying to control the frequency of noise using a colour attribute. I have managed to do this on a grid but I cant figure out how to do the same using a volumevop. My goal is to be able to control the amount of detail/scale in specific areas of the model. Im not sure if this is t...

Hi guys! I'm trying to restrict volume density by Bounding Box and Ramp. I created FitRange and Ramp nodes. When I move sphere by Y axis I can modify FitRange MIN and MAX values manually to keep density restricted. But I can't import min and max values and wire them into min and max inputs of Fit...

Why directly indexing into a given component of a vector field using parm type float doesn't work ? For example volume prim having a named attribute "test.x" isn't accessible with the same name of type float inside volume vop. Some insights will be helpful Thanks, -Gaurav

Hi, Guys. I have just begin to learn volumevop. I bulit a vel volume form attribute N. What i want to do is modify the vel value in volumevop. But how to import the vel attribute to volumevop. I try to use Primitive Attribute, or Get Attribute, it seems not work at all. Any help will be great...
