It would be nice if the models that have already been rendered did not have to re-render when other models get swapped out and the comparison view re-run.
First I compare AHQ, AMQ, and Theia.
I find that I like AHQ so I keep that, but I replace AMQ and Theia for two different variations of Proteus.
I re-run the comparison view. Since AHQ did not change, it would be nice if it didn’t need to re-render.
Then I run a third compare: I tweak just one of the Proteus views from the last run of the compare. That should be the only one of the three views that would need to re-render.
The above should save a lot of time when swapping out just one or two of the views in comparison mode, especially when this is done a few times in a row and when the user selects a larger number of frames for the preview.
