Houdini point color to Maya vertex color on changing topology
Sounds good. Found what I was looking for. Thanks again.

Awesome!!! That worked!

How would you go by linking that up to an Arnold Shader? From my understanding, you need to create a aiUserDataColor node and plug that into the color attribute of an Arnold Shader. I'm just not sure what to feed the aiUserDataColor node. 

Also, just to be on the same page, when the color is being applied in maya, are we applying the color to points or verts. I'm assuming the gradation in color wouldn't be as smooth on verts?

Thanks again! Very excited to add arrayToPointColor to my workflow!

Definitely! The alembic file is just an exported cache from the Houdini color mix example I posted above (incase you wanted to check out the project as well)

Still no luck. Maybe my setup is off? I've attached a screenshot of my node editor.

I've went ahead and created a aiUserDataColor node and referenced the color set name as the "color attr name". I then plugged in the aiUserDataColor node as color in my aiStandardShader. 

Could I be setting up the alembic file wrong? I'm just using default ROP alembic output settings. Should I be deleting and/or promoting any attributes? 

Thanks again!

Houdini point color to Maya vertex color on changing topology
Hello, 

I'm creating a flip sim in Houdini where the colors of the dynamic object mix. Similar to this:

 

I'd like to transfer the mixing point color of the simulation to maya and use it as an animated albedo texture in an Arnold shader. I've managed to import alembic files with color sets into maya, but only when the alembic file is a single frame. Unfortunately, I haven't had any luck importing multi framed alembic animations with changing topology while retaining point color information. I've done some research on the forums, and from what i gather you're supposed to use the arrayToPointColor node. So far that hasn't given me any results. 

Does anyone have a suggested workflow for something like this? Would I be better off converting the changing point color to a .png sequence in Houdini and then using the sequence as a texture map in maya?

Any help would be much appreciated. 

Thanks
