hi, i am using rays to detect collision :
in blender, normals directions seem fine :
normals and raycasting are not related.
Can you repro in a PG?
It’s really not new to me, when I made the bullets and the rockets I saw it:
Upload to PG takes a lot of time, unfortunately i no have much time, i will continue searching more about it, or i have an alternate solution, apply a field force in that area, for avoid the player keep on that area
