I'm a newbie to Blender's compositor, so I don't know if this is possible or how to do it.

I want to be able to automate the process of combining multiple animation frame renders into a single image for a character turntable collage, whereby the front, front angle, side, back angle, and back renders are side-by-side as a single image. Typically, I use an external image editing program to load all the the images into a single canvas, crop them, position them, and then export the combined image. Being able to automate this process in Blender would be more efficient and accurate.

The reason I do this is to quickly compare tweaks I've made to a character between major changes as I work on it by switching between composited images using an external image viewer.

I have a single camera pointed at the character and it is parented to an empty. This empty rotates around the character for five frames for each view angle stated above. I render out the animation, and so on.

  • I think this could work, but give me a minute to try it (and some time to get that minute lol). In the meantime, I recommend you look into the compositor yourself. You might figure out how to do this with file inputs and overlay. – TheLabCat Oct 15 '21 at 21:36
  • I think the fastest way to use Blender to generate the composited image is to actually import the four frames into the VSE as 4 tracks one above the other; set the blend of each to Over Drop, the scale of each to .5 and the position to offset them. Render that and you get a 2x2 'split screen'. If you're willing to do the whole thing using two blend files it would be pretty easy – Marty Fouts Oct 15 '21 at 22:42
  • Appreciate the responses. Looks like a hacky solution was linked by a moderator (I'm assuming?) which uses separate scenes and a relatively simple node setup. – ITellYouHwat Oct 16 '21 at 05:58
