This is my first time useing blender artist and I am fairly use to the program but for some unknown reason when ever I go into play mode. I can see into my character and I can’t find a solution. I will post pictures of the problem and a link to file below and thanks for takeing the time to read this.
You need to recalculate your normals. Select the mesh, go into edit mode, on the tool box to the left of the view port hit the Normals: Recalculate button.
Your UV-unwrap is somehow corrupted, a workaround is to create a new uv-unwrap and perhaps bake in the old uv-unwrap. Strange enough exporting to .obj and importing didn’t resolve the issue, while deleting and creating a new uv-unwrap did.
