Use more than 2 UV channels - how? about realtimemeshcomponent HOT 4 CLOSED

Some further info after digging deeper:
I am trying to use a FRuntimeMeshVertex<true, true, true, true, 3> VertexWithThreeUvs; directly resulting in an error: error C2039: "TypeInfo" missing

Also tried adding a DEFINE_RUNTIME_MESH_VERTEX(FRuntimeMeshVertexTripleUV); and DECLARE_INTERAL(...) which results in a crash.

It's been a while since I've tried it and the macros have changed a bit since then and you're also the first to ask about using more than 2 but...

You should be able to do it via a combination of something like..
DECLARE_RUNTIME_MESH_VERTEX(FRuntimeMeshVertexTripleUV, true, true, true, true, 3, ERuntimeMeshVertexTangentBasisType::Default, ERuntimeMeshVertexUVType::HighPrecision)

in the header and

DEFINE_RUNTIME_MESH_VERTEX(FRuntimeMeshVertexTripleUV);

in the cpp file.. if that doesn't work let me know. I'm not able to test that right this second.

Thats how I declared it, and this crashes the engine in RHI somewhere with errors about NaN in matrix transforms. (not at my PC right now, to be more precise). Don't know what is happening there, as in the initial material I use it doesn't take the additional UV channel into account at all.

Btw: I really like the well engineered code you produced! :-)

All Good, the template with three UVs works! :)
