How do I fix the mesh's hitbox from blender?

I was using terrain and parts to make maps for my golf game. Because terrain collision is weird and I wanted to make a mini map, I came to blender to try and create terrains. I saw a tutorial for the basics, made a simple mesh just to test and as expect, the collision geometry isn’t near to accurate:

Can someone help me with this? I saw that Synty’s mesh have great hitboxes, and I wish to achieve something like that.


Have you changed the CollisionFidelity of the MeshPart to PreciseConvexDecomposition? It can be found under properties and under the Collision category (may vary and be under a different category).


Yes, and it did help a bit, but there still is a lot of invisible hitboxes still.
