Refraction

now i know we can do reflection easely, how about refraction? how would 1 go about cubicmapping to simulate refraction?

Afaik, there isnt a way. Cubemapping wont help here. On my pervious post podperson mentioned the use of pixel shaders but I dont know how to implement them in Blitz.

Try playing around with SetCubeMode, it's not documented, but it does change the way the cube mapping acts.

ya i tried setcube mode and using texture blend to 1

altough it kinda looks like refraction, its really not accurate at all.

You can't. Pixel Shaders weren't introduced until DX8 and Blitz3d is DX7.
