1- hi, i was playing half-life 2 and i saw that the water fully refract in the parts that are near to the player and fully reflect when far from it, its possible to do this in 3dgs?

2- in the examples that i see about dynamic cube maps, all are generated in the water origin, but, for example, if i put a hollow cube in this origin, the cubemap will be wrong? how i can solve this?

It may.. but I dunno, but post tutorial request, may help

And i luv the shading in HL2 They're too awesome


(Ach, u need Mirror in the reflect, other parts are simple)

They use a fresenel lookup to blend between refraction and reflection based on view angle with the surface. Not too hard to accomplish. It's not LOD at all.
