as far as i know a mesh has a collision based on the shape of the mesh but i would like to have a sphere collision for saving performance. when i add a sphere collision to the mesh does it replace the collision? or must the sphere be attached to the sphere collision?
In the UE mesh editor, press Collision → Simple Collision, and you’ll see what the collision is. You can either delete the existing collision and add a sphere collision, or add a sphere collision on top of the existing one, your choice.
thank you, that was the information i needed. but i cant mark the answer as solution because you made comment.
