Fluid Creation help - m.mokhtar89 - 17-09-2022

Hi people, hope you all are well.

I am going to pay for the OBI unity asset, and i have checked the documentation.

I have a question about creating a cup filled with liquid to be used for VR game, i couldn't figure out how to do that in the documentation.

All what i found is to create emitter to provide liquid flow.

If i have the cup and liquid as mesh objects (as attached image), how can i turn the liquid mesh to be a liquid, so when the scene starts 
the liquid simulated stable in the cup, so i can interacting with VR controllers to simulate liquid moving.

I really need to know if i can do that with obi before pay for it.

Thanks in Advance

Just add a ObiEmitterShapeMesh to your emitter, set emission mode to "burst" so that all particles are emitted instantly, and you're done. See: http://obi.virtualmethodstudio.com/manual/6.3/emitters.html

Quote:Emission method

Emitters can use one of two emission methods:

Stream:
Particles will be constantly emitted, as long as there's at least Min pool size particles in the pool.

Burst: <--- this is the one you want to be using.
One particle for each of the emitter shape's distribution points will be generated in a single burst.

You need to use separate cameras for each eye, as the renderer does not support stereo rendering. See our FAQ:

Cloth, Rope and Softbodies support VR. For Obi Fluid, you will have to use separate cameras for each eye since the renderer does not support single-pass stereo rendering.

Very Good
I think that when XR plugin enabled for oculus, something went round with fluid color, it's become transparent
