tahkns Grayson Peddie is 6.3
for the water reflection your need a enviroment cube sader ...OK
and your need a model to atach the sader ...ok
but the model need split in little faces and to move continually so that you work
solution:
your need wait for a6.3, and put a enviment cube sader in PH_WAVE entitie
form ventilator older quote:
fixed function environment mapping doesn't work with flat planes because all normals point in the same direction and the view vector doesn't get calculated for each vertex individually.
you could use an animated water plane with some waves. not all normals will be the same then and the reflection probably will look better.
