Simple compositor problem for noob.

Support Compositing and Post Processing

Greetings Blender peeps,

I have very little history with using the compositor so I’m sure this is easy for the pros, but I can’t possibly come up with a search phrase that would have helped me, so I’m doing something I rarely do and ask a question before researching it. I found this kick A$$ skull on blender swap and I want to edit one of the eyes in the compositor, so I move it to another layer and assign a render layer to it (2) and when I do blender assigns the compositor node tree from the skull to the eye. And when I try to delete the node tree from the eye and start a new one, it deletes it from the skull. I hope I’m describing this right. It’s difficult. Anyway, I have done a simple blur and glare node tree for something else before, but I didn’t have a big node tree for the main scene messing things up. How can I make this work?

I can’t upload the file because it’s 71 MB. I can zip it down to 21MB but I guess either this site doesn’t like zips or it’s still too big.

use object and material index. make sure the index passes are turned on in the scene properties.

Composite.blend (1.89 MB)

the first method uses material index, the second uses object index(found in object properties -> relations). the node group in the compositor simply splits up the scene based on index. currently setup to use method 2.

NOTE: this scene uses no color management (not sRGB)

thanks for the input, but just as I suspected, this stuff if just way above my pay grade. If I can’t follow along a simple tutorial like this then I’m not going to be able do do anything like this. https://www.youtube.com/watch?v=fWcCkQ3943Y

thanks,

Don’t lose heart: you just have to debug it, just as you must do with any computer program. :yes:

thanks for the reply and thanks for the vote of confidence. Wish I had the time. Got so much other stuff going on. :eek:
