Bug / Crash Fluid Renderer doesn't work on two sample scenes

[redhairjino]

Hi there,

MultiphaseFluidBuoyancy has the exact same rendering setup as the rest of sample scenes, there should be no reason for it to work differently. SimpleFluid however uses the simple renderer instead of the standard one. It should show no lightning or reflections, just colored refraction.

Can you describe in detail what the problem is with these scenes?

I've reinstalled Unity and updated Nvidia graphics drivers to make sure every other things are all up to date.
Unity version is now 2018.2.4f1.

I've created new project in Unity, then imported Obi Fluid 3 to the project.
Then went straight to Obi>Sample Scenes and opened all 11 sample scenes.
All sample scenes work properly when I pressed Play except MultiphaseFluidBuoyancy and SimpleFluid.
Both doesn't show fluid on Game window when played. 
It shows particles when I check 'Render' check box on Obi Particle Renderer, but doesn't render fluids when I uncheck it.
It seems like Obi (Simple, too) Fluid Renderer doesn't function properly, but I can't see anything wrong with the settings.

If you want screenshots or anything else, please let me know and I will gladly post it here.

Thanks.
