>>58254314there should have been individual variation in species since at least gen 6. It is ludicrously easy to make 3 models - a baseline, a "minimum extreme", and a "maximum extreme" and have the game select different points of the model to place somewhere in that range. Can also include leaves/feathers/spikes with a random placement filter very easily and slight individualistic variations, like sugimori eyes vs slightly bubblier ones or whatever and have them be selected at random, too. This is something that games have been doing since 6th gen... as in since 1999. Color schemes are the easiest option too because they can literally just feed the texture through a +/-1% rgba filter and have alt color schemes be baked in alternatives that can ALSO have those variants. It would be trivial for the largest media franchise in the world, but alas, game freak is simply a small indie company.
