Z-depth problem
Posted: Tue Jun 23, 2015 10:11 am
Ok so this is my probem.
Screen is from Fusion 7 compositing software.
1. I create a render.
2. I get a Z-depth map. What's important is: what is what is close is dark. What's far rom camera - is white.
3. I use Z-depth preparation node and have to invert it because the:
4. FOG node uses white color as near plane and black color as far plane.
And now I have the problem because I have fog only where objects are. Where HDRi is, there is no fog.
Shouldn't the Z-depth have WHITE color in background. In fact it's in far distance and far distance in Z-depth from Octane is colored white.
If everything is fine and I'm making myself a problem than is there any way to overcome it?
I could create an alpha mask to cover the black areas and than overlay it on white image, but I'm not sure if this is a good compositing behavior...
