[Lightmass] TextureMapping.cpp - missing "* 3" when getting Triangle

[DomiOh]

Hello,

there is a mistake in the TextureMapping.cpp file of UnrealLightmass at line 1920.

Original:

const FVector4 TriangleNormal = (MeshVertices[TriangleIndex * 3 + 2].Vertex.WorldPosition - MeshVertices[TriangleIndex * 3].Vertex.WorldPosition) ^ (MeshVertices[TriangleIndex * 3 + 1].Vertex.WorldPosition - MeshVertices[TriangleIndex].Vertex.WorldPosition);

In my opinion it should be:

const FVector4 TriangleNormal = (MeshVertices[TriangleIndex * 3 + 2].Vertex.WorldPosition - MeshVertices[TriangleIndex * 3].Vertex.WorldPosition) ^ (MeshVertices[TriangleIndex * 3 + 1].Vertex.WorldPosition - MeshVertices[TriangleIndex** * 3**].Vertex.WorldPosition);

Greetings,

DomiOh

No clue if you’re right or not.
Still, it’d help to go through the motions and see what come so of it.
See How to Report a Bug.

Thanks
