Cubemap Seams

[aWilson41]

Great learning resource! Thanks!

I found when applying similar techniques in OpenGL and testing on a sphere with some amount of roughness that I needed to add:

 glTextureParameteri(id, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
 glTextureParameteri(id, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);

To the cubemap textures to prevent any visible seams on cubemap edges.

Might be useful to anyone that finds it.
