Texture Mapping with a Circular Texture I have a planet texture that I would like to map onto a UV sphere. The texture is a circular texture (I have attached it below).

Currently, I've been using a node setup that works for mapping matcaps onto spheres. However, it just causes the texture to be pixelated on the mesh, even when I apply a subsurf modifier.

Any help will be greatly appreciated!
The texture is only half of the sphere. If you UV-unwrap the half UV sphere by "project from view", e.g. in X direction, it could work, because the texture is itself projected from view - but I haven't tried myself.
