Hi,
I would like to know how can extract Zdepht on a PositionPass. In Nuke i creat a shuffle and extract Blue or Green channel (depend 3D software) and by a Grade i picked-up black / white balance to creat a Zdepht.
In fusion try to recreat the same workflow, In loader .exr RGB>PP.R, PP.G, PP.B then switch to blue channel but what kind of tool i'll be able to grade my Zdepht...White balance ? BC ? and after ?


thx in advance,

This approach only works in case your camera looks along the Z-axis.
Once the camera is rotated, or moreover, rotation is animated, such extraction of a single coordinate doesn't work anymore.
I would suggest using the ZToWorld tool.
Then you can adjust the range with a BC indeed, or with a BitmapMask, depending on how you're gonna use it further.
