Hi. I created an RPF sequence from a 3d program with a character walking forward (changing their z-depth).
I brought this into After Effects CS4, turned it into a 3d layer, and I can get Depth of Field working fine.
When I try to use the 3d Fog effect, I'm able to control the onset of the fog with a given z-depth, but once the fog appears, I can't get it to go away (there are start depth and stop depth parameters, but I can't find any values that let the character start in the clear, walk through a patch of fog, and then emerge in the clear on the far side again.
Any suggestions on this?
ANyone able to help with this question about using 3D Fog with a rpf sequence from 3d Program?
Sorry to disappoint, but the problem is probably more a case of wrong values being produced in the 3D program. So provide a file from the sequence for inspection and we might have a look. On a side note, you also should pre-compse your RPFs before turning thme into a 3D layer. AE doesn't like 3D-ish effects on 3D layers and this, too, can cause odd problems.
