Help Pre order questions

[HellFingers]

Hello, I want to buy Obi Fluid, but i have two questions:
Can I use this asset like for water in pipes. You wrote that it shouldn`t be used like Large scale fluid simulations, Pools, oceans, lakes, floods and i can't understand does this include my case
Is there any way to control water collision with other object by code

Hi,

Depends on how many pipes you have, how much fluid you want in them, and how detailed you need the flow to be. Obi is a particle-based simulation, stands to reason that in order to simulate an ocean or even a lake you need hundreds of millions of particles which isn't going to run in realtime in any existing hardware (unless you use particles the size of a car, in which case the fluid will look chunky).

Is there any way to control water collision with other object by code.

Yes, you can:
- Filter out which fluids should collide with which objects, using collision filtering. This can be set up in-editor or programmatically:

- How fluids should react to a collision with an object (slide, stick, etc), using collision materials. Again, can set them up in editor or in code:

- Get a list of all contacts that happened in a frame, and react to them:
