Raycast adjust level of detail


for example if I import a car tire model from blender to ue4 and do raycasting on it, it is not accurate enough for my application.

Black dot is the car tire. The red polygon is the area which raycasting say “here is car tire”. :smiley:
For example detecting if a bullet hits the car tire is then wrong in some cases.
Is there a trick to solve this?


The collision mesh is usually lower detail than the object, so if you want it to be more accurate then you have to use a higher detail collision mesh.
