But at 1.08 when he takes the sphere shape, If i take a sphere I’ve got a meshe, and if I take a collision sphere, it won’t work. Can you explain me ho to do it with the 4.10 version please?
You probably confuse Sphere (a static Mesh) and Sphere Collision (The Collision in the video).
You also need to make sure that the Sphere collision generates Overlap Events and the Collision of your character is set to something that is set to “Overlap” within the Sphere Collision Settings.
