Hi guys... working on a DX7 engine... Found a strange issue here... I decided to use the Specular Colour item in my vertices ( allocated in VBs ) to use it as specular value or emissive value when I need... well... I am working on a Lo Profile platform, to check items with lo level CPU/GPU... well, I found that on a GeForce2 GTS, the specular Value seems to be completely ignored, like it is nonexistant, so that if for example I assign Diffuse Colour to the Colour2 ( Specular Colour ) item, i see all objects dark... like the vertex got 0x00000000 value in that variable... So I have checked, the value was there, and, doubtfully ( at least ) I tried on an old ATI 9600... yep... on ATI it works... I can see the specularity I want, of any colour, while on GeF2 the specularity seems taken from light property, not from the Vertex value... Is GeF2 too old..? for what I know it should be DX7 compliant ( it's Caps show it ), and tried with latest draivers too... no way... is it an HW bug/lack of capacity? any Advice/Info...? tnx...

I worked with DX9 on GeForce2 for quite some time. And I only noticed specular alpha to be ignored, color was fine. I've also read it somewhere in official documentation (but I don't remember where exactly), that this is just as it is supposed to be.

As for DX7, it could be only worse ;)
