1) You set in the corresponding ObiEmitterBlueprints' Capacity field
2) Easiest way is to just set the lifetime to be a large value
3) For a rough estimate, you can count the active particles through ObiEmitter.activeParticleCount. You can take a look at IObiParticleCollection and ParticleImpostorRendering for more info.

1) Yes, you set your blueprint's capacity. Link to the manual: http://obi.virtualmethodstudio.com/manual/6.2/emittermaterials.html

2) When setting the emitter's lifetime to a *very large value*, note you can actually set it to infinite by typing the word "Infinity" into the numeric field, and pressing enter. This trick works with any numeric field in Unity, not just Obi's.

3) Count particles if you want a rough estimate, if you want the actual volume in cubic meters then multiply by the volume of a spherical particle: 4/3 * PI * (radius)^3.

- create new URP project with Unity 2021.1.28f1
- import Obi Fluid, clicked "Yes to all" in the conversion dialog
- imported Burst
- got warnings in playmode: referenced script (Obi.BurstColliderWorld) missing (and one other)
- manually imported com.unity.collections
- I can run the sample but everything is pink
- Edit => Render Pipeline => URP => Upgrade (all) materials
- Scene runs, console does not log anything, but fluid is not rendered (btw turning on particles works as discussed above)

How do I get Obi to display fluids in URP?

I'll record a video and link it here so you can see which steps I'm taking in case I missed anything.

Quote:-Add a ObiFluidRendererFeature to your pipeline's renderer feature list.
-Enable Opaque and Depth textures in your pipeline.

TBH assets that I know which require setup remind the user about that with a popup or similar so there's no RTFM questions. Something to consider for a future update.
