To reduce memory I am experimenting with two channel color compression reflection cubemaps - for example only using two channels to represent an RGB color. Has anyone else tried this? How were your results?
I was looking at this: http://www.codersnotes.com/graphics/two-channel
Unfortunately with this approach I can't find a great set of coefficients that work well.
I tried using James Blinn's approach but then having a constant hue looks really bad.
I also tried packing RGB24 to RGB16 but the banding I got was terrible...
Anyone else have any ideas about this?
