blur and z buffer

[tallosy]

Hi!

Can I use the z-buffer of a 3d scene to control a blur?
You know what I mean, that the blur is stronger in the far backround and more decent in the nearer objects of the background?

thanks,

Try use the 3D Depth of Fiel and/or G-Buffer Builder

ok, this seems to work with RLA files.I have TGA – sequences for foreground, background, shadows and the Z Buffer…

any ideas, how i can combine the strenghth of the blur with the luminance value of my z Buffer sequence?

use your Z buffer as a matte for an effect layer with blur (ughh… it’s a little bit AE…)

Use the G-Buffer Builder for create the Z-depth of files or use the Compound Blur and use the Z-depth pass as map

you can do it a few different ways. the ones above are true, but this pdf is a more “traditional” (read: old school) way
