Unable to use Compound Collider as Trigger Volume

Hello everyone!

As described in the title, I encountered an issue where compound colliders don’t act as expected when using them as simple trigger volumes without a rigid body component. I would expect the compound collider to fire the “triggerenter” event when a rigidbody enters the collision volume. Instead I get nothing.

However, when I add a rigidbody to the compound collider and register to the “collisionstart” event, I get the expected result.

I believe that it is set up in the correct way, where the parent has a collision component with compund collider selected and multiple children with primitive collision components.

This problem might also be related to this forum post from 2021.

After a brief look at the issue page on github I didn’t find anything either.

Thanks for the help,
Chris
