[RESOLVED] Vertex painting does not respect tessellation?

cjwidd

Very straightforward issue: import a plane with 4 faces, tessellate in the shader, then vertex paint. Despite tessellating to thousands of polys, vertex paint only respects the *original* vertex count? 

Stated differently: You cannot paint on tessellated vertices, only base mesh vertices(?)

Thank you for confirmation
I assume this is because in different situations (e.g. adaptive tessellation, camera based tessellation, etc.) the position of the subdivided vertices will be constantly changing, so a vertex color cannot be assigned based on world position, or something like this?

Yeah tesselation in UE4 is really only meant to be adaptive and completely camera dependant. It can't really store veetex data because it's always changing. Just subdivide your shit elsewhere.

Yeah subdivide your shit bro. XD
