With the chain as active and ground as passive created rigid body. Why the chain unable to drop on the floor. Chain is going through the mesh. Any suggestion whats going wrong
There are many reasons why your mesh is falling through the floor. After examining your file, I figured out all of the problems, and I will tell you how to fix them.
first off, when I downloaded your file, your plane did not have any rigidbody physics attached to it, so if your plane does not have passive rigidbody physics, then that is the first thing you need to fix. (also, make sure the collision for both objects is set to "mesh" in the rigidbody settings)
Next, your chain mesh has a lot of modifiers on it that are messing with the rigidbody simulation and confusing the computer. to ensure a smooth and good looking simulation, go to the modifiers tab on your chain object, and apply all of your modifiers.
After that, it should work like it's supposed to. Hope this helped! :) If you encounter further problems on this topic, feel free to let me know.
