What is the different between Fluid Effect and Bifrost ?

What is the different between Fluid Effect and Bifrost ? And How to make fluid like oil running in the pipeline and export to Unity 3D?

Hi!

There are no easy answers/solutions for both questions.

1. You can achieve similar effects with Maya Fluids and Bifrost, but the new Bifrost Graph offers far more versatility for complex effects. If you are a beginner I recommend to experiment with the the available tools to get a better understanding of how they work and then decide which one to choose based on your requirements.

2. Volumetric simulation data as well as particle simulations can't be simply transferred to Unity ( meshing the result and using Alembic as export/import format may be a usable solution)

I recommend to build the whole animation inside Unity by using the built-in particle system or Visual Effect Graph, which is also particle based.

Can I use Maya's animation system to do simple keyframe animation, and then import unity to do water flow effect with unity's own plug-in system? Will this waste computer performance

I agree with Mspeer. You just cant simply export as fbx from Maya to Unity. Any kind of particle sims for Unity or Unreal is done completely different. There are many tutorials regarding creating liquid for Game Engines.

Hi!

Please check the Unity User Manual for supported import file formats and data types.

You can create meshes (also with keyed animation) in Maya and transfer this to Unity and then in Unity add the water flow effect, this is the recommended workflow.

What do yo mean with "waste" ("Will this waste computer performance").

Using the dynamic system of Unity is the most efficient option and allows for interactive parameter changes, which is usually the main reason for using a game engine.

If you don't need interactivity then you can also render out an image sequence with Maya/Arnold.
