Render underwater view of simulation?

[davision]

I have a camera within a volume of liquid. I'm getting strange results when using a water type material (basically the same material used in the "pool" sample file). The water surface is like a mirror which reflects the objects sitting at the bottom of the pool. No background (outside the water) can be seen through the water surface.

Turning down the reflection doesn't help.

you have to decrease the ior of the material

[davision]

Decrease it to what? Isn't there an exact number?

[Ivaylo Katev]

i suppose you are observing Total internal reflection, and it should be like this.

Very interesting. Yes, I suppose that's what's happening.

Thanks.
