Get Vertex Color/Mesh Paint in HDA July 2, 2026, 2:55 p.m.
Hey, this actually tripped me up not too long ago as well.
Nothing has changed on the Houdini Engine side. Unreal made an update recently that requires you to send the vertex paint to your mesh. In the Vertex Color panel, where you have your 'Paint' and 'Fill' options, you need to hit the 'ToMesh' button. This assigns your painting to the actual mesh in the level, then Houdini Engine is able to send that Cd data over.
Let me know if that doesn't do the trick and we trouble shoot some more.

Thank you for the details and steps here. It might be best for you to write up the bug as an RFE, that way the developers can track it a bit better and you can stay up to date on any progress.

Hi Tom, those are quite the cook time discrepancies you have there. I was wondering if you could provide a test hda or hip file to see if we can investigate this further? If you are getting those results in Houdini, I don't think it is anything you are doing wrong on your end, but we won't really know for sure until we can repro this on our end. You can message me privately if you want to share the files that way, or you can make a bug report.
