Im trying to create a mesh geometry from another software whose co-ordinate system is Y-up.
When i try to create the meshes i had to flip the vertex as shown in below code
FVector vec = FVector(x, z, y);
FVector vec = FVector(x, y, z);
But only the inner surfaces are rendered as shown in the attachment.
Can anyone help on fixing this ?
Also what is the minimum data like (VertexPositions,WedgeIndices,WedgeTangentX,WedgeTangentY,WedgeTangentZ
) is required to render complete and perfect model in UE ?
What is causing this problem ??
Thanks in advance
