Depth pass ignoring material’s alphas
Hello, I have a scene set up with multiple square planes, each of which have a raster material assigned to them that has an alpha channel which mimics the raster art in the color channel.
Example:
https://litteritcher.com/ms/dof3.png
https://litteritcher.com/ms/dof4.pngThis renders fine as an RGB image – https://litteritcher.com/ms/dof2.jpg – , but when I try to do a depth pass or use other features, the alpha from the material is ignored and the entire square plane is used to create the effect – https://litteritcher.com/ms/dof1.jpg – .
Is there a way to get cinema to use that material’s alpha when calculating a depth pass? I have also tried the “depth of field” effect, rather than doing a pass, but the alpha issue is present there as well.
Thanks!! – Jon

AR DOF has that problem. There are a couple plugins – ZBlur and enDOFin that can properly deal with alpha.
A tut here that shows a method (time intensive) to do DOF a different way – https://www.per-anders.net/tutorials/tutorials.php?index=7
and there is a photoshop method which I’ve read described as “All you need is a cam, an ambient illumination light with near and far clip (rear blur and front blur) enabled and a 100% pure white material.” but I don’t know the trick since I’ve never needed it. Somebody knows though.
