I have a model on which I want a patch of PNG texture but the rest of the model has no texture. What I want to achieve is:
Where the texture is not transparent - render the texture
Where the texture is transparent - render the material
Where no texture is defined - render the material
I can get the texture to show up in BlenderRender-view by turning on the material's 'face textures' option (having UV-mapped the faces that are to be textured) but this seems to turn off the material color (and I just get grey where there is no texture and black where the texture is transparent - presumably the texture is set to black under the transparency in the PNG).
Probably either something simple or I am taking entirely the wrong approach.
