Having trouble with collision groups

I’m trying to make a surfboard system for water parts. I’m using collision groups to make only the surfboard collide with the water, so it gives the impression of surfing instead of sinking in the water., like this.

So I’m using collision groups to make only the board collide with the water, not the fin.
The water has CanCollide off in properties, and the board has CanCollide on in the properties.
Water:

Board:

I’m using collision groups, but it doesn’t seem to work.


The whole surfboard keeps falling through the water, the whole board.
The board and the fin and welded and have weld constraints, they are not in a group or folder, they are seperate but welded.

Hello.
Usually this could just be a random bug. I actually had this problem prior. I would try doing the following:

  1. Uninstalling then re-installing studio
  2. Make sure studio is up to date, this. ould be the main problem as if studio isn’t fully up to date then it gets behind and some stuff doesn’t work properly as this could be the main reason.

Once I updated it when I had this problem before, it worked just fine.

Let me know if this works or not.

Thanks for the reply! I have tried reinstalling Studio but it didn’t work.
2 things:

  • When I test it in “Run” the surfboard falls through the water, but when I test it in “Play Here” I get this result:


    It’s kind of hard to see, but the surfboard does what I want to do when I test in “Play Here”. Then after a few seconds it falls into the water again. It’s probably a bug.

  • How do you check the version of Studio?
