Collision Shape
Let's create two Collision Shapes so that the model in the game does not waste our FPS.

Select the round sphere and create a radius. After this, adjust the scale of the sphere so that it is centered and covers about 90% of the model.
Enter data (Vertex 1) of 2 spheres in Edit Node - Pivot Point
As a result - Everything is ready
