I found a post from the creator of shark bite which explained a bit about how it worked/works. But it seems there is no way using collisiongroups or anything else that I can find to allow you to:
have a part that:
collides with water (floats)
does NOT collide with solid terrain materials
Does anybody know of a workaround for this? Or is it just not possible?
As far as I know, all terrain falls under the same category, so water or any specific material can’t be separated as it is all simply “terrain”. Perhaps there could be a workaround using raycasting of some sort, but it’d probably be a lot of work and very clunky as well.
It seems they were considering adding this functionality, but it seems that it has fallen by the wayside:
I might use this method as a workaround, but it still doesn’t give the ability to collide with water(float) while not colliding with solid terrain materials.
Goal: invisible floating part that cannot collide with anything other than water!!
