I followed a tutorial https://www.cineversity.com/vidplaylist/bullet_time/bullet_time_part_12
With success
However the issue comes from me trying my own spin on this
Shapes made editable grouped together with a null - Simulation tag Rigid body
Mograph Motext - Simulation tag Collider body
Result - Rigid body group falls through the Motext without collision
My setup - All simulation settings are default
