Hello guys ! http://www.babylonjs-playground.com/#1E3DCH#2 I do some experiments with the native function moveWithCollision and the ellipsoid parameter for meshes. I don't know what dimension should be the ellipsoid here or the ellipsoid offset.   Our character is the red man and the obstacle is the blue box. The character should collide with the obstacle. I want to test collisions with man on the floor and box at different y positions : box on the floor (collision)
