I have this fluid sim in Houdini with two different volume sources that I want colored differently. The nodes are properly set up from what I can tell and the export to C4D seems to have worked.

Where things get tricky is setting up the materials properly in Octane in C4D. I'm using an instance color node plugged into the Albedo channel and the node is being drive by the Cd attribute vertex tag I exported from Houdini. Unfortunately for me, the material is only showing one of the two colors (blue).

Does anyone know how I can fix this? (I'll provide image links below)

I hope this question gets answered..I have the same issue but with redshift..Identical issue.
