Noob here, I am making this models in a common software called B%%%%%, I don’t know why but they look so bad annd their collisions are not working, I tried to fixx in by changing some details but nothing has changed as I see.
Looks like some normals are inverted. in Blender (B%%%%%??), activate Backface Culling, now the model should look the same as it does in UE, then in edit mode select all the faces of the model and press Shift + N. If shift + n doesnt wok for you then press F3 and search for Recalculate Outside.

Hey there @NEYSE_O001! I agree with Pezzott1, it looks like the normals on those faces are flipped. Just to add more context here’s the Normal functions and their explanations in the Blender official documentation:
However with your collisions, after reimport if they are still having issues, you may have to do a bit of troubleshooting. The first thing I’d recommend doing is going into the of your mesh in Unreal and seeing what the collision looks like using the collision views:
This will let you see what the collisions, both simple and complex looks like at the moment.
You may have to regenerate the collisions if they aren’t ideal. There’s lots of ways to do this, and this page here has multiple (dated but still viable) tutorials.
Hope this helps!
