This brings up= another question though - when rendering from a 32bit project to an 8bit h= 264, how does AE tonemap the values? Does it tonemap? is there a way to cha= nge this, or a filter to use?

Are your luminance values clamped at 1.0 in t= he EXRs or do they go much higher?


= If they are clamped, I've read you need to disable straight alpha in yo= ur render if you're using C4D, to get what you need.

I've done nothing like this before, so this answer = is purely off of some quick research and googling. =A0If it doesn't mak= e sense, it's because of that.=A0
