I'm always amazed at how people come out with these blatant statements of "you cannot do this in this or that" when they don't know the program... BT is right, you can do this in Bryce and it's easy once you know how... an even easier way of doing this is to use the flat circle to create a "water surface" within something, say a fountain, or in this case, a backyard pool... So, this is the quick and dirty backyard pool: Get a torus, stretch it out using one of the corner handles to make it big... Go to radius and change it to 128... Give a texture... Give the landplane a texture... Then take the flat circle and in the aerial view, stretch it out so that it fits within the hole in the torus, but is slightly bigger than the hole so that it goes into the torus... Give the flat circle a water texture and tah dah! you got water in a backyard pool... :) I'll also mention that this took me less than 5 minutes in Bryce... Guaranteed, it would take 2 hours in 3D Studio Max and would not look as good... :) Moral of story: use the right tool for the right job... :)
