Hello.
Sometimes I need to delete the background from an image, making it an alpha map.
I have been trying to add an alpha map to a mesh but with no success. I have UV the mesh and added the image
The settings are like this:
All of them have a glossy red (diffuse color) material. The bottom row has the alpha image, the first sphere has the M button (Multiply texture by color) turn ON. the second sphere has the M buttun turn OFF. The third sphere has the M button turn OFF but with the Luxrender Alpha Transparency box checked set to Difusse/Reflection alpha, and set the texture to Luxrender Type Image Map, Wrapping: Clamp.
The fourth sphere has the M button turn ON, with the same settingsas the third sphere.
The top row of spheres have the same settings as the bottom row of spheres, but the image has a white background.
I rendered the images with Blender and Yafaray and they come out as I want them to, I do not know what am I doing wrong here, Luxrender is so different from the rest that it needs a special way of handling materials and textures , I was looking for some info on the wiki but I coul not find anything, unless I missed some stuff wich I probably did, but hey, you are the experts.
