Also, would it be possible to support other train mods, like Electronic Locomotives? https://mods.factorio.com/mod/Electronic_Locomotives?from=search

I updated the mod to 2.0. As of now the mod keeps the vanilla animations for vertical rotation on ramps. In the future, I might add smooth version for these sprites too.

I also tried to make it "support" other mods, by making them use animations from my mod, however I did not manage to get it to work.
If my mod loads first, I should be able to overwrite the base game locomotive and therefore other mods would use these graphics along with it.
If my mod loads last, then overwriting prototype data from other mods should also be possible.
None of these worked for me today, but perhaps someone knows how to do it properly and can provide a fix.

Also it seems that developers have rendered all sprites again for 2.0 and changed some rendering settings, this can introduce inaccuracies: minor lighting and color artifacts. I would have to run the whole process of interpolation pipeline again at some point.
