Kelsier Posted May 26, 2018 Share Posted May 26, 2018 (edited) Hi, I am currently looking into building a rig for putting a object into a flowing river. now the problem is three fold. 1) the main problem is that the river is pretty damn flat, 1 degree decline max. 2) its a big area 60 meters long, 50 wide 3) the river is moving very slow now naturally i could simply animate the collision geo against the flow at the speed i want the river to flow and then counter animating the cache post sim. that way i would get the interaction with the object the way it should be. now the problem is that i only get the interaction that way, and would never get the feeling of a flow in areas where there is no collision objects. I tried a few things, sourcing new particles on one side while a continues force at the bottom of the river pushes the water. I tried grabbing the particles that will leave the put them to the start of the container, making a infinite loop kind of tank. The problem with all of those is that I loose water. basically the longer the sim runs the lower the water level will be. In the end of the day I will want to be able to take a flat tank at any size and just have the water run through it at any speed with out loosing water. If anyone has any suggest I would highly appreciate hearing about them Cheers, Juri Edited May 26, 2018 by Kelsier 1 Quote Link to comment Share on other sites More sharing options...
