Compositing a scene with external images?

Is there a way I can use the compositor on images that are rendered from another scene? I’m practicing with the compositor and I have rendered a scene with 3 layers from another file, but I don’t know how to tell Blender the image isn’t from the current scene.

I can’t seem to get the external image to show up, even when I have a viewer node and backdrop checked.

If the images are already rendered like you said, you would add an input Image Node and select your first image. I think then you get to choose if it is an image sequence or not and you choose the frame range you want to use.

Yes. And, render the output as MultiLayer OpenEXR files.

This file format will capture the exact digital data produced by the renderer – separated into “layers” such as shadow, specular, Z-depth and so on – and make it all available to you in the File Input node.

This format is expressly designed to be used as a digital intermediate-data file in a multi-stage pipeline. It was originally developed by Industrial LIght & Magic. The “multi-layer” extension was added by the Blender Foundation (and immediately adopted). You should use it for every step up to and including the “final print,” which might just be (non-layered) OpenEXR. Generate all of your “deliverable files” from that master. In this way, you won’t “throw away data” except in the final video-compression stages.

Hello! I just realized I hadn’t replied to this one, so I am very sorry for being so late.

It seems Hunkadoodle had a solution that worked for me, but I still appreciate your input! Thanks! :slight_smile:

I assume it still IS thee best answer provided here, no the former, but then did any one else not know about this tidbit of info on Render comp file formats-openEXR, multi-layer data and such, then realize it was so simple and SO important but didn’t get the acknowledgements . . . good if not best answer. Way to obvious not to reply from my veiwport.

I’m not really that advanced in Blender… so I try to go with the simplest solution. :wink:

But I am happy for any input I can get. :slight_smile:

Thanks for OP. That was the assumption I had and I was hoping fifty other people would agree/admit that this was commonly unknown, but it doesn’t matter. It was such a cool post, I wanted to bump or antagonize, and it was worth trying.
