Some Questions About Obi Fluid

[josemendez]

Thanks for the answer, I'm using Obi Fluid 4.1. 

What I want to know is what is particle baker is and what is the purpose of using it? I imagine that, it is something like for example recording the fluid effect and then using this in the game without emitting any real time particles.

Thank you again.

Hi,

The purpose of the baker is to record the position of particles during a simulation, and store them to a disk cache (an asset file). They can then be then played back as if it was a video. The cost is lower than performing a full simulation, but no interaction with the particles is possible during playback.

Alembic lets you perform any simulation of any kind in an external, high-quality simulator (Houdini, RealFlow, etc), and then import the resulting mesh sequence into Unity for playback. Offers both better performance and quality than the baker, so we removed it.
