I am trying to scale and repeat a Cubemap with Latitude-Longitude mapping layout just as you would do with classical UV mapping but without any interesting result. This should be used as a skybox.
This comes from the fact that the coordinates are in 3D space and we can't apply this simple formula
texcoord.xy * scale.xy + offset.xy
How would you handle such features : scaling which involves tiling and offsetting.
samplerCUBE _TexCube; texCUBE(_TexCube, float3);
