Hi,

I just loaded the production build today. I'm pretty new to Houdini, but I'm going through the tutorials.

I'm using the stone shader off the material shelf. This surface moves around my objects when I do simple animations. It looks like the shader is rotating or moving differently then the object. It also happens when I attempt to make my own simple surface shader.

This problem is happening on both systems. I don't know if I'm missing something real obvious, or if my display cards (Nvidia GTX 450 on one system, and a Nvidia 650 Ti on the other) are messing with me? It happens no matter where I animate from, and on unaltered geometry as well as altered.

So is it something obvious I need to learn, or do I need a pro workstation card like a quadro 4000 or 5000 to render surface shaders correctly?

Thanks!

Barbara

See if adding a RestSop helps

Thanks!

It works now like it should. I was hoping it was something dumb that I missed!

Wow, have I got a lot to learn.

Thanks again.

Naw it isn't that much. Just some standard “Houdini” workflows.

As for the REST attribute, we Houdini'ites love it when models come in with a default rest attribute to help stick procedurals. Especially with RBD fracture chunks.

Also helps out with Characters if the God Pose is baked in to the rest attribute too.

Yep. Don't forget the Rest SOP right around the texture SOPs on the geometry before it gets deformed.
