Regarding the issue of bullRob in the tutorial

[Lnferior]

In order to familiarize myself with the use of Coppeliasim in version 4.6, I was replicating relevant tutorials and during the review process, I found that the relevant user interface had undergone significant changes compared to version 4.1. I couldn't find where to set up noFrictionMaterial in the shape dynamics properties mentioned in the tutorial.
What is the specific setting method in version 4.6?
I'm sorry, I won't add local images in the forum to better explain the issue I described.
Cheers

Hello,

in the material dialog (Engine properties button), make sure that everything that is related to friction is 0, e.g. friction, frictionOld, staticFriction, kineticFriction, etc.

Cheers
