Filtered Z-depth trouble

[Laserschwert]

I have a problem when rendering a z-buffer along with my image. I uncheck "filtered", because I need the pass without anti-aliasing (so that the DOF-plugin doesn't produce artifacts). Yet, some parts of the buffer ARE filtered:



See the edge of the front wall? The Z-buffer against the floor is aliased, while the Z-buffer against the back wall (which is the same mesh) is filtered. I assume that unchecking "filtering" only works between separate meshes. Is there any way to fix this, without rendering the Z-buffer separately?

The samples are grouped for each object; so even if filtering is turned off, samples belonging to the same object will still be blended together. To separate them, you will need to break the mesh in two parts. There is no way around this, unfortunately, other than rendering the z-buffer separately.

Best regards,
