[Bf-committers] New procedural texture: Planet

[raulf at info.upr.edu.cu]

Thanks Tomas :)

  Yes, indeed will be very helpfull for your sci-fi project, as soon as
Lapinou upload it check my site http://farsthary.wordpress.com , I made
there a comparison with current textures to see their limitations.

    I will polish today the patch and will release it by tomorrow, hope it
will help you, is a fairly simple patch and will not disrrupt anything
in Blender

                                Cheers   Farsthary
