I´m modelling a Saturn-like planet, and for its rings I simply used a plane with a texture for the rings. It´s a simple PNG file (no alpha), so I used for the material a white color, the image texture as an ALPHA, alpha value as 0 and Ztransp activated. I rendered it, but unfortunatelly, the light over the rings plane also affects areas of the plane that should be transparent too (please see the attachment). Any tips?
Thanks in advance.
