Help Colorless liquid particles (URP).

[josemendez]

1) Where to set the number of particles?
2) How to make the particles not disappear but just stay in the cup, filling it.
3) How do I calculate the volume of fluid in a cup?

CreepGin's answers above are correct, just for completeness:

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