"Calculating irradiance maps for short fly-through animations in one go. Instead of using the Incremental add to current map mode and rendering the animation every Nth frame, you can turn the Use camera path option on, and render just one single frame - this will produce information for the entire camera path."
says in the manual, but
if i put that in practice, i should be able to achieve all details of the animation by rendering only once , just selecting" use camera path" on "single frame".
but that does not do that yet in my case.... what i get is a flat GI , 2.5 mb irradiance map , no artifacts though...
