Help Newby lost, Trying to make a robe bridge

[oppay]

If you attach a rope inside a collider that's set to collide with the rope, the simulation will behave in a weird way. Think about it: you're asking the rope to stay inside a collider using an attachment, but at the same time to stay outside of it (since that's what collisions do). That's simply impossible to achieve, an object cannot be simultaneously inside and outside a volume.

You should use collision filters to solve this. Note that you don't need to set both the entire rope and the collider to "collide with nothing", you just want to set the endpoints of the rope to not collide with the collider's collision category. For more info on how filters work, see:

So to make my rope bridge i will need to attach all the plank to the rope, but set them in a different collider filter then the one of the rope? It sound pretty redundant to add a attachment manually for each plank. Is there a better way to connect them?
