I don't no what I did wrong this time,I use radiosity_start and my map pop up,but the bitmap is mest up and my water looks like someone bit half of it.

I presume you named the water material in 3ds max/gmax with just the name "water" then the required symbol for render only and/or fog.

It is using the b30 water shader by default, and if you look at the base map within that shader and view its alpha you will see the shape of the island that won't be visible.
You either need to replace that base map with a white texture and compressed with explicit alpha or copy that shader into your maps directory and do the above. The latter will allow you to keep the unmodified b30 shader.

Im using 3ds max 7 for got to say that, I made a plane and names it water!$ I fix the other bitmap problems I just need to fix water now.

I tryed b30 water shader but now it's even worse than before,its only a small water the size of my hand.
