[SOLVED] Cant import mesh due to poly count

Got a 164000 vertices x 54000 faces x 54000 tris mesh and I'm pretty sure it won't crash the game since I extracted it from another game and I have to say, there is way more meshes that got more than 150k and 50k and my pc, just like any other humans' pc, runs this game totally fine. So why not in Sims?
Can I disable this limit anywhere? Also will it even import it? I mean if I should just wait few hours... I can wait lol
