How can I add functionaly of simulating physics for CustomMeshComponent ? It currently detects collision but not simulating physics.

Unfortunately it’s not designed for Physics atm. You will need to create your own custom physics objects, I did this by extending UShapeComponent. But I have yet to find a perfect solution. I have however managed to create physics that approximates the custom mesh. Due to the way it does the creation of the physics meshes, it simplifies it too much.
