I use loot and i have loots of crashes Having a perfect load order may not prevent crashes. Many mods with scripts can bloat your save, or old scripts that are not deleted when mods are uninstalled can negatively affect your game. Check for save bloating, there is a tool for cleaning saves, I just don't remember what it is.

This could be a mesh issue, it depends on what is happening. But most likely it is just conflicting or incorrect textures, the normal maps probably. You'll want to find the loose textures for each mesh and delete them (or just move them somewhere, like your desktop, for testing). Your mods probably have textures in a BSA while some loose textures (possibly from an old mod) are conflicting with the new changes. You can use this tool to know the exact texture assigned to each mesh: https://www.nexusmods.com/oblivion/mods/2156 It's much easier than loading each mesh in nif skope
