Custom colliders / Interaction with Obi Particles

[davidrousal]

Ah perfect, thx for your quick answer. The part with the collision is fine. For the water you misunderstood my bad english question maybe

I want to add an area of water (my water, not an obi water) and this should affect your simulation particles like other gravity, damping etc...
For example: I want a swimming obi rope on a water box (no obi particle fluid)

thx a lot

Ps: if you have another idea how I could simulate non-obi water to affect your particle simulation I would be happy to hear it, hehe
