ah no, it's output from mental ray. Not clamped, full 32 bit. but that did start me thinking. I realized the gamma for the blended passes was probably the issue - set it to 2.2 and now it looks good.
This brings up another question though - when rendering from a 32bit project to an 8bit h264, how does AE tonemap the values? Does it tonemap? is there a way to change this, or a filter to use?

What program are you rendering from? C4d?
Are your luminance values clamped at 1.0 in the EXRs or do they go much higher?
If they are clamped, I've read you need to disable straight alpha in your 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. If it doesn't make sense, it's because of that.

Hello, I am working on a project with some rendered realflow fluid sims, and I'm at the final stages. I have my multilayer EXRs imported as layers, and I'm trying to reconstruct the beauty pass from spec, refract, reflect, shadow, diffuse, AO, vector, motion blur and indirect passes. (output from Mental Ray) I am getting pretty close by using add modes on spec, refract, and reflect, and then multiplying the shadow pass, but when recomped with the background it is way off, and especially once I add ambient occlusion. It looks extremely burned out. I am in a 32bit project. I haven't found any tutorials that are too good about how to layer and blend these passes in AE. Usually I would do this in Toxik / Composite or Nuke, but I prefer AE's layer and keyframe handling better. Especially because I'm going to strip each layer away for a demo animation. Anyone have ideas or can point me to a good tutorial? Thanks,
