Hello,

I wanted to ask because I've found an issue when working with houdini engine in UE5 and vertex color info giving me different results

So for the test case, I just dragged a Labs Measure Curvature node. Then in a attrib wrangle I copy Curvature to @Alpha like this:

Then in unreal, I did noticed, that the default info in @Cd.r added by the curvature node doesn't match what's on the @Alpha. I also manually exported and imported the mesh and the thing is, when using the ROP FBX output, the resulting mesh does not have such issue.

What am I doing wrong/missing?

No one? it looks like for vertex colour it applies some conversion, not sure if they are being stored in sRGB or not. Does anybody knows?

Hi , I had the same problem with not matching Vertex color.
After some searching found that there was a bug in Houdini Engine not aplying Linear space color conversion when getting Static Mesh from Unreal.
Bug was fixed in HE version 2.1.1, but I have to use Unreal 5.1 (project requirements)
and on this version the bug is not fixed yet.
