I absolutely adore these kind of tools from you
They may be extremely specific and especially this feels like I would have never asked to have it. But just seeing how insanely easy it is to use just gives me ideas on how to implement it.
Outside of just having neat rotating animations this could have some use for chopped rotating textures. Export the rotation as png-zip and then only use every 10th image to get the look of a choppy rotation. Though that workflow would probably be a bit more intuitive if you could just specify how many frames per rotation it should render in the zip export.
Honestly that thought may actually be THE solution to an artstyle-problem I had. Will test that out later.
