Physics: Simulate a rack and pinion linkage

Hi everyone.

I would like accuratly physically simulate a rack and pinion linkage like this:


However, even if the pinion and the rack meshes have lots of triangles, unreal doesn’t seems to be able to decompose the collider into enough triangles:

Is there a way to simulate it by using physics in unreal or should I find another way (the rack could be vertical in some situation so replace it by a rectangle and the pinion by by a cylinder doesn’t seem to be a good solution)?
