While I could be wrong, but I dont think that there a commercial/pro differences with respect to shaders. The differences as to which shaders work and dont is strictly due to graphics cards/drivers.

Yeah, but I believe some of these shaders use "CameraSpaceRelflexionVector", which I thin is a Pro only feature. As I uderstand, this feature makes realtime reflection possible.

I agree with Qwerty, as in I don't think that there are any differences in shader support between the commercial and pro versions. Nothing in the manual would seem to indicate so.

Thanks for clearing that up qwerty,
I don't know much about shaders you see.

qwerty823 is right on those. The thing that I find interesting is that all the code at the beginning of this thread worked on my ATI. While only the one labelled water_test_5 showed up on the geforce cards. Ventilator and Alkai both ran water_test_1, 2, ,3, ,4 & 5 and _only_ 5 showed up. Now why is it that in 5 I had to pass a DOT3 Normalmap _through_ Gstudio's bmap_to_uv() ?? This I do not know.
I would be curious if one could use the SDK to create the textures like in Microsoft BumpWaves.exe and if it would make a difference on the cards.

So the fifth water test is the only one that works with all the Geforce Cards? Thanks.

As far as I can tell from different posts... yes #5. I hope that someone who has one of the geforce cards and likes to dabble with code can determine why that is.

Hmm, without going back and looking at how the stages were done, but are you saying you wern't passing a bmap_to_uv()'d bmap in the other shaders? From my test (ill have to dig up the thread), it looked like bmap_to_uv() changes the texture format to D3DFMT_V8U8. I'm wondering if there are cases where ATI will happily use other formats, and nVidia cards are stricter.
