DOF - want better blur quality!

#1

I’ve rendered an image in 3ds max, made an output to a FPR-file with Z-buffer info included.
Now, I want to do some 3D DOF in Combustion, but I have problems with the quality.

Currently i’m using the 3D DOF with the Box blur, but it gives me too many artifacts (otherwise, works quite well and fast!).

I want to use the Gaussian blur to get a better result, but I really can’t seem to get it work: Nothing happens - no matter how i tweak my settings with the gaussian blur!

Any tips on this topic?

I always get better results from using a compund blur operator on the footage. You can use a greyscale Z-Depth image as the source layer, basing it on luminance. If you are doing rich pixel renderings, you can use a show G Buffer operator to show the Z-Depth, then use a blend operator to revert back to the colour layer (you can still pick the show G-buffer layer as the blur source - it saves you from having to set up 2 layers)

Thanks Chris for the tip on using the blend operator :thumbsup:
