I'm mapping a plane with an image, but I need to make the background of this image transparent. I try some tutorials with layering in the texture room, make decals, but they always use a background color at the end. I need to have transparency in the background. I manage to get something similar to this. but when I set my scene background color to white, I have some problems. is there any simple and basic process for this? when I uncheck the transparency in my render, the color of the image apear ok, but the transparency is needed. Also I'm, not sure if I need to use a layer over my plane. I'm using carrara 2.
