After creating some complex objects and scenes and importing them into the PlayGround, I noticed that lighting wasn’t looking like it should and so I added a small debug-function to the X-loader for outputting the vertex normals into the vertex color to see if normals were loaded correct. And guess what? I forgot to multiply the normals by the rotation part of the meshes’ matrix, which caused them to point into wrong directions.
