I want to create a depth Blur effect in DFX+ with an LW generated rpf image. But when Im using the "Depth Blur Tool" in DFX+ I`m getting trouble with the borders of the objects. It looks like bad anti aliased.


I hope you can see what I mean.

After consulting the DFX manual, I think the problem is the wrong export of the "Z-Coverage Buffer" and the "Background R/G/ and B Buffers". How can I create these Buffers in a DFX compatible way with LightWave??

Thank you

What does it look like when you use no Alpha channel on your image?

Seems like something caused by an alpha channel...

Try taking ADAPTIVE SAMPLING off... the depth is read out by the Z-buffer, I found that in some cases, taking Adaptive Sampling OFF and setting AA to enhanced, it will AA the Z-buffer as well.

Hope it was a help...

In LW8, isn't that what the Depth Buffer AA is for?

I think that is what the coverage buffer is for but it doesn't seem to work in this workflow (Depth buffer AA doesn't seem to work either). An Eyeon rep told me that the best practice is to render twice the final size then reduce in DFX+ to get a good AA.

Edit: That is twice up with no AA.
