Hi, i have problem with the light shader! It is strange and i don't know why. i wrote the light shader, and apply it to the obj mesh, and i run the app at different PC, there are some strange different results: the light keep shinning on and off; or the light become dark; and so on.
why the result of lighting at different pc is different? i really wonder to know! thanks in advance!
Findout GPU of the other PC, if you have ATI and there is Nvidia, there are standard differences between those vendors. One I have experienced is that Nvidia behaves to texture slots differently, and it seems your texture bound to a slot is inproper, as you say that light is off or dark. I would say the texture does not get bound to slot some frames. You have texture on slot t0.
