Depth Pass in After Effect HELP !!!

[gbaillot]

Hello to all 

Sorry in advance for my English, I go through google translation .

I can not simulate on After effect has the depth of field  . My frame is white (. EXR).
Impossible with the exposure compensation to get a map to degrade from black to white (as in the tutorial performed by Luxion on Photoshop).

Or more simply, how to simulate the depth of field in After effect with the layer "Depth Pass" (.Exr)?
Someone can you help me??

Thank you

Impossible with the exposure compensation to get a map to degrade from black to white.

Your After Effects project is probably set to 8 bpc color depth.

You'll need to set the color depth to 32 bpc (EXR in KeyShot is a full float image format). See attached image for how to do it.
