Should I write out the diffuse and specular to separate 8bit or 16bit buffer ? or should I just render it like Diffuse + Specular to a single 8bit or 16bit render target ?
What's a common approach to this ? I reckon doing separate buffers and also in 64bit might be quite expansive...
I currently do it like Diffuse + Specular to a single 64bit target, does that have enough flexibility/precision ?
