View Full Version : multipass & AO question

I made a multipass render with only an ambient occlusion pass, no rgba image. I used the default settings and saved as a .psd file. Although both the AO and rgba image are displayed in the renderwindow, the final .psd file only contains the rgba layer, even when opened in photoshop. After trying again as a .tiff image I got the result I wanted.
This does not make sense to me, can anyone confirm and/or explain this?

Hi Erik,

It is strange indeed. It's just like you say it is.... But why not render an RGBA pass as well if you only need an AO pass? It won't affect your rendertimes I think.

Cheers, Lex

Hi Lex, nice to see you here :) I thought it would save rendertimes and there's no real problem since I can just render as tiff instead of psd. But I don't understand why psd doesn't work, sounds like a bug thing to me.

I usually render to PSD when using multipass. I've had occations where a
single pass doesn't get rendered but adding another type of pass it works.

However, rendering the AO pass using PSD, try uncheck "Multi-Layer File" and
you get the AO pass correctly.

i noticed that too, when i want separte ao pass i also add an rgba pass and they both show in the psd, otherwise you just get regular rgba layer, haven't tried tcastudios's solution but it would make sense if it worked that way :)

I was told by Maxon that you always need an rgba layer in a multipass file, in addition to whichever other passes you require. Don't know why, but there it is.

Cheers,
