Don''t know what''s up with above post...

But anyway...
A simple method to do some simple environment mapping, is to use the vertex normals. It must be a smooth/round object.
You can transform your normals to world space, and only use the x & y part of the vector as texture coords.
(ps: better not translate these vertex normals to world space: only rotation)
