Pretty Basic Zdepth problem...

[need4cg]

Are you rendering your Zdepth images with an .RPF/.RLA export with Z Depth activated? That's what usually works with the depth filters in DF.

Found it out already!

I rendered the Zdepth maps as seperate images, that was indeed part of the problem. I fixed that using a channel boolean. But the pronlem of the background blurring I solved by putting the Depth Blur before the Merging, so now I have 2 Depth Blurs, one for each layer...

Thanks anyway ;)

... and a new problem arises... The blur seems to be chopped off at the edges, perhaps because the alpha channel has hard edges and in this setup is used to merge the layer áfter the depth blur... does anyone know how to fix thís??

This is most likely caused by the fact that the image you are using right now doesn't have a z coverage channel. As far as I know, the only application that outputs a propper z coverage is max, in the rpf file format.

Well, I'm pretty sure it does. I have rendered the Z-depth map as a seperate image (jpeg), and this looks fine, and used a channel boolean in DF to copy the image to the Z-channel. I can actually see DF using the map and I can control the depth blur just as I want it, but there's still the hard edges around the character where they should be blurred...

try turning off "Depth Merge" on the merge connecting your photo image and images w/ depth information...if that doesn't do it post the flow....it's kinda hard to imagine all the ins and outs that could be causeing it

hmm rendering z buffer image in jpg is not realy an z buffer. For that you need some of the file formats that support floating point format like tif, iff, ...

Do, You can make for some specific needs grayscale images faking true zbuffer field by using 8bit images.
