I have read a handful of posts regarding this with older ECS versions and am hoping things have changed. I need to scale a physics shape mesh collider at runtime? Is this not possible? The manual says: Scaling colliders All collider types can be uniformly scaled at run-time when they belong to a dynamic rigid body. This can be achieved by modifying the Scale member in the entity's LocalTransform component. That sounds straightforward and simple, so I am doing something wrong or completely misunderstand this.
