G-buffer UV coordinates not anti-aliasing

[insleight]

Checking G-Buffer passes in Nuke. All of them come in un-anti-aliased. Anyone know the workaround? Is it a nuke or vray issue?
Adaptive DMC
LanczosFilter 2

Tried different Anti-aliasing filters as well as turning it off.

Thanks

What file format do you save to? Only the .rpf file format provides the deep pixel data with the proper antialiasing information.

In general, the G-Buffer is not "antialiased". Instead, it contains deep pixel data for all objects in that pixel. For example, if there are two objects contributing to a pixel, the G-Buffer will contain two separate values for the UVW-buffer in that pixel - one for each object - along with their coverage (instead of just one blended UVW value). A compositing application can use this information to do proper sub-pixel blending of this information to give you the antialiased results. I am not sure that Nuke can do this, though.

Could anybody maybe give a hint on how to use the coverage pass in nuke ( i dont even know if it is possible)? Thorsten?
