Cubemap projection onto a sphere I need to be able to generate texture coordinates on a sphere for cubemaps textures. But somehow I seem to fail in Blender to accomplish this.
See the image below as example cubemap.

I am able to map the texture correctly in Unity by using an cubemap asset, but I am unable to reproduce this behavior in Blender.
If on a spherical mesh, you can start with a cube (rotate its UV to fit your map), then add:

Subdivision modifier with &quot;simple&quot; algorithm (we don't want to smooth but just to give more geometry for the cast below)
Cast to sphere modifier
