Z-Buffer combine
hello outthere,
does anybody know a way to use the Z-buffer channel in After Effects for compositing (z-blur, etc) if the file exists as a seperate 8bit picture (tif). I need a function like Channel-Boolean in Fusion. The Problem comes from Cinema 4d, that not aible to render rla/rpf files with integrated z-buffer through net-rendering.
Any ideas?
thanks in advance

If you can render a separate file with depth information from your 3D package then you should be good to go… I’ve even seen people fake the depth information by adding a black fog to their scene and rendering with all white materials.
You can use this render in a similar fashion as the 3D Channel effects, although it is limited to only depth information (no id, material, or other info). For example, you could use it with a Lens Blur effect to get a depth of field look.

I have the same problem.
A workaround for some of the cases is to use the depth image as a luma matte and adjust depth with color correction (curves, levels, aso) on the depth image layer.
But for the “real cool stuff” like z comps it doesn’t work…hopefully someone out there has a solution…combining a grayscale into the z-aux-channel in afx …or even better render z info integrated on net render….
