WorldShadows and NormalizeMesh() make entity disappear

[Samuel]

When using WorldShadows, if you create a mesh and then normalize it using NormalizeMesh(). The mesh will not appear when you display it on the screen. If you comment out one or the other though the mesh displays fine.

Code: Select all

Your code works fine if custom mesh is substituted with CreateCube() for example. It might be the order you create faces in, or something along the lines.

[Polo]

Had this issue as well with custom meshes!

Well at least i know I'm not the only one having this problem. I'll try changing around the order of the face creation and see if anything happens.
