No transparency

[sirpauldk]

Hello.

I hope someone can help me with a problem I have in mental ray.

I have started on a model of an Olympic size swimming pool, but I have some problems with the water material. The problem is that it isn't transparent from under water.



For instance, in real life when you look up from the bottom of a pool, you can see some of the things near the water, people, the springboard and so on. But when the camera is above water as you can see on the picture below, it shows the bottom of the pool as it should.



Here are the settings I have used for the water.



I'm using Autodesk 3ds Max Design 2010 64-bit

What am I doing wrong? Please Please Please help.

I assume that you are using a flat plane (not a box) for the water surface, if so make sure under advanced rendering options thin-walled is checked.
