Hi guys, so recently I've started to play around with FEM. It is a simple FEM object that supposed to collide with my animated ground object (bullet) unless it didn't. I've checked the shape of my collision object and it is fine.

The funny part is if I didn't add the animation to my bullet ground object, it works just fine.

I also tried to use the ground plane from shelf tool and it works absolutely fine with both static or animated one. So my guess is that I probably missed something important working bullets and FEM.

Any ideas around it??

You may need to activate Deforming Geometry on the Static Object of you animated the ground plane. Otherwise you will only collide with the state of the ground plane on frame #1. Are you seeing any collision?

Hi.. I did have it checked on but still.
Can you check my file maybe.

Thank you btw

Thanks for reporting this. Deforming Geometry definitely should be turned on, but regardless there seems to be an issue here.

I've added Bug 82569 for this.
