I tried to create an environmental mapping for a sphere by using Blender’s UV/Image Editor. As you can see in the attachment the generated result is disappointing (created with the smart projections unwrap function).
I know the possibility to manage environmental maps over Blender’s material buttons, but the generated result has to be exported over an *.obj file into an OpenGL application. Since materials in OpenGL and materials in Blender are different as day and night, it is only possible to go over the UV mapping.
At the moment I am out of ideas, so I am happy for some help.
