Summary:
Problems rendering multiple scenes composed with defocus nodes

Detailed description

Hi! :D

The situation is this:

I have 3 different scenes. On the main one I have the main scene, with defocus node. On the second and the third ones, I have objects for composing them with the first one so I get a glow effect. I'm testing this for a bigger project and I get this issue:

-As in the main scene I have defocus, on the "glowing objects" scenes I need to have defocus too, so in the borders of the objects that appear in front of the objects that glow I don't get hard edges, but a defocused one, just like in the main scene.

When I apply the defocus node to the second and third scene render layers, even I mute that nodes, blender crashes while rendering with f12.

It happens to me always. I notticed that I was using a linked camera in all the scenes, so I tried to make it independent on each scene, so I could select different objects for marking distance, but it continues crashing...

I attach the scene for you to test the situation ;)

Good luck!

I notice that of the three scenes, 2 are Full Sample AA and 1 not. If you set all to FSA things should work... but that shouldnt be needed. Will check further tomorrow.

BTW: We have an official release candidate for 2.57 on blender.org frontpage. Also crashes though. :)

Thanks for the example. It took me quite some time, but the fix was found. Was a mistake in code other more complex node setups will benefit from as well from!
Fix goes in svn now (rev 36091) and will be in release.

Thanks a lot, Ton :) Yeah, I forgot to mention it, but I also tested it on the official RC ;) I didn't notticed my error not activating FSA on every scene. This afternoon I was testing this further with a more complex scene, and I didn't get this error, I suppose that on this one I actually activated FSA on the three scenes.

Thanks for your work, and good luck with the release!! ;)

The error was related to using the same renderlayer node twice with two DOF nodes.

You can also just use 1 renderlayer node, and connect it to 2 DOF nodes. :) that works fine, and is the default we test for FSA.
