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:
@Alpha = @Cd.r;
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.
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.
