_FluidDepthTexture not found

After reimporting a native plugin, you need to restart Unity. Native libraries are only loaded by Unity at startup.

Fluid will not render in the scene view, as Unity only applies image effects (and fluid rendering, being a screen-space method is one of them) in the game view. You can still see particles in the scene view for debugging purposes by enabling the "render" checkbox in the emitter's ObiParticleRenderer. See:

I see. The red errors are not shown after restarting Unity.

But "Command Buffer caution" is still shown when playing example scenes.
Then I deleted Obi folder to reimport. But when I restart Unity after deleting Obi folder, Obi folder revived.
Obi folder seemed to be imported automatically at restarting Unity. 
And "Command Buffer caution" is still shown.

I don't know why I can't delete Obi folder...
