I was wondering if there is a way to edit a png texture to allow light to shine through its alpha channel, as. As though the transparent alpha in not actually present in 3D space to block the light. I am using Blender Internal with a spotlight to cast god rays behind my object, and as of right now, the transparency on my mesh plane is blocking out the light. Any
Any solution is greatly appreciated, and if you also know how to solve the problem in Cycles, I'm open to that option as well (as I know I will be completing similar projects with Cycles as well).
Thanks!
