Using COPs to generate a UDIM texture May 24, 2022, 5:14 p.m.

So I have a project that I am working on where I am using attributes from a point cloud to generate a texture map in COPs. Normally, I've not had a problem doing this, but the model that I am working with has UDIMs. And I am unsure of how to generate the correct texture map for that. Looking at the COP network, the effect is not matching with where the UVs should be.

Is this not possible with COPs?

Sparse pyro sim not rendering May 20, 2022, 2:24 a.m.

A weird issue just popped up for me when I suddenly couldn't render any of my pyro setups (I just get black screens). So I opened a brand new hip file and created a very basic sparse pyro setup. I used a DOP Import Fields and import the fields I need. I hooked up the Pyro Bake Volume, and the pyro shows in the viewport, but it doesn't show up in the render.

I have the hip file attached. Can someone please put their eyes on it and see if I'm missing something?

Particles not stopping during a collision May 8, 2022, 9:36 p.m.

I have a simple POP system setup where I am launching several particles at a surface. I'm using a heightfield for the static object and using the collision detection on the pop solver. I also checked the box for "Move to Hit" and set the Response to "Stop". However, when the particles come into collision with the heightfield, they simply bounce off the surface. They are not colored as a hit by the solver either; however, the Geometry Spreadsheet shows that a collision did in fact occur. Has anyone had this specific issue before and know of a resolution. It's really been perplexing me for a while now.
