How do I change the Player's Collision Group from Client?

[Q2ddz (paradigm)]

Sorry for the wait.

Tienke’s solution will work, but also know that you can modify collision groups on the client, but not create nor delete them.

I also recommend doing a Google search instead of creating a new post completely, it not only saves effort but also time as well.

Local collision filtering

The only part of PhysicsService which is server-side is the ability to create and delete groups as well as modify the collision relationships between groups. LocalScripts are still able to set a part’s collision group for local collision filtering. So long as the server creates the groups, the client is good to go.
