Hello,
I'm getting up to speed on lightmap_write and I hit a roadblock. I was wondering if someone could help me debug my approach.
Here is a link to screenshots of my lightmap_write setup. Click each thumbnail to see the full size image: http://dugla.backpackit.com/pub/1076384
Simple scene: groundplane, lambert shader, area light source. The surface shader is diffuse red with no ambient component. The area light source is white.
My issues:
1) The resultant rendering is not what I would have expected. The rendering somehow has transparency in it that appears to correspond to the intensity of the light source. Brighter areas of the surface are less transparent. What the ...?
2) A texture is baked however it is a greyscale (but 3-channel) image that appears to be the luminance of the rendered image. Huh?
I have no clue what is going on here. I've checked and rechecked everything and can't figure out what I've done wrong.
