Why do my models look crazy on launch, but fine in Editor?

Hey everyone! I created some models in Blender using the Manuel Bastioni Lab. They look great once imported into the UE Editor, but when I deploy the app to my Pixel 2 XL, those same models look like something out of Silent Hill (see attached photos). Any idea what’s going on? (fyi, I’m not by any means a 3D artist, hence my use of MB Lab lol)

Check if you’ve exceeded the vertex limit
Manuel Bastioni meshes are not usually optimized for games

If it indeed has surpassed the limit, you’ll have to do some retopology then make a normal map

There ended up being a few default modifiers that Manuel Bastioni applied. Just make sure to disable those modifiers in Blender and everything works fine.
