A few questions to get things started and help make things more clear:
It is a bit hard to tell what exactly is happening or going on here. Is the water supposed to be in the pipe? Not supposed to be in the pipe?
Can you describe in more detail what the end goal is that you are trying to accomplish?
From the picture provided its difficult to to see what the actual error is. We can see that the pipe is moving in and out of the liquid, is it not supposed to do that?
Any additional specifics or information you can provide may go a long way in solving your problem!
The goal is that the pipe have be consider as a collider for the water. The water and the pipe are in there correct position in my picture, I just want the water collide and bounce when it touch the pipe mesh.
I already put box with tag “collider” on the scene (there are invisible) to make the black hole you see, so the simulation detect well the collider mesh.
The final result is use in sequencer to render a image sequence, not to make a game or any realtime software.
Okay, I can see what you are trying to do. What do the collision mesh for your pipe meshes look like? Are those not enabled by default? If there is not one, even if you enable collision, there would not be any data telling the collision how to work.
Try setting view from Lit to player collision and see how the pipes look.
