Mesh Geometry not getting rendered properly after flipping the orientation
Hi 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); instead of 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
The coordinate system shouldn't matter in normals! All would happen is that the WHOLE MESH would be tilted by 90 degrees. You should flip the "faces" (normals) of your mesh in your 3d app! ...you can try two sided material in Unreal...
