The has water box was already ticked but I couldn't see any water, so I changed the height but still no water. When I clicked back on the cell's properties the water height had changed back to 0.

I can't get the water to appear at all, I tried clicking apply instead but it does nothing. I've also tried changing the water type, water noise texture and water height various times but none of these has any effect. The water just doesn't want to appear.

I'm hoping that I'm just being dumb and missing something obvious... all help appriciated, thanks =]

As far as I know, you have to use placeable water in interiors.

aah yeh i see how it works now. Cheers buddy =]
