Mod requests (orders).

Hello everyone! I have two questions for the Heroes experts. I decided to play through the Orc campaign and noticed some things I would like to fix: 1) Are there Orc models with better detail? It seems to me that the Orcs look the most "plastic," especially levels 1-3. 2) I've noticed this before, but it's especially noticeable in this campaign: heroes seem to "twitch" (double) when moving on the global map. I noticed this with the hero Kujin in the "One Khan, One Clan" campaign. I could talk about the engine's capabilities, etc., but when playing as Toulun in the same campaign, there is no such issue; he moves smoothly. I have removed all hero replacer mods. I wanted to ask if anyone knows where the hero movement is encoded in the files, at least to compare the code for these two heroes and find the differences, and there is a chance to fix it.
