Flip: Collision & separation between two fluids.

[ibaniser]

Hello guys,

I didn't get any answers from the sidefx forums so I'm trying my luck here.

 I am simulating urine from a medical cup going into a toilet bowl. Obviously, the water in the bowl is going to be clear, while the urine would be yellow in color. So I will need two separate objects to bring back into Maya for rendering (this is necessary).

My current setup is successfully colliding with each other (the urine and toilet water). I am not sure what the correct way to set it up was, but this is currently how it is set up:

* Urine fluid particles are sourced from a flip tank sop that's pruned– to match the shape of the cup that's holding the urine. That is then imported into the autodopnetwork through the flipobject sop and put into the first input of the flip solver.

* The water in the toilet bowl is sourced slightly differently. For this one I did the same process by making a flip tank, pruned it and then made that a vdb and used the fluid source sop. This one is put into the fourth input of the flip solver.

The reason I did this set up was I just could not get them to collide with my previous method. I tried making them both into flipobjects and merged them with mutual collision (i also tried left affects right) but they wouldn't interact. With the current set up, they do.

Now I am wondering, how do I isolate the two different fluids so I can export them as separate objects, is it possible? 

Would appreciate some help, thanks!
