Collider issue

[Dutchbird]

How can I avoid objects going through the wall of my collider object.
Scene attached.

Hi Dutchbird,

Thanks for the file.

Simulation scene settings
• The scene scale was at 100cm
• The iterations were at default (Simulation scene settings)
• I lowered the Gravity to -98.1

The Rigid Body TagCollider tag
• I increased the Search Radius to 2cm
• The Collision Shape is set now to Complex

The Container had some extra polygons inside.

The search radius needs to be seen in connection with the speed the object has while considering how often it is checked (iterations)
To have a higher gravity means (without any other influences) that each second, you add 981 cm per second to the speed. That can exceed the iterations and search radius quickly. All in all, it is a balance to find in the values. I would start with one layer, 8x1x8 instead of 8x30x23, to see how the initial values work, then adjust accordingly.

I placed a plane below the container to see if there are "escapers", this plane can be deleted.

Let me know if that works for you

All the best

@Dr-Sassi thanks again. I’ll check it first thing tomorrow morning.

[Dr. Sassi]

You're very welcome, Dutchbird.

Let me know how it goes.

Cheers
