I have an ATI rage card and when I start the Irrlicht Demo in DirectX sometimes (not always, but often) it has a problem with the lightmap. It flickers between the lightmap alone and the texture alone. However the flicker only appears at the same texture where ever it used in the q3-map. And when it flickers that texture seems to be blown up.
PS: the lightmaps aren't used on my pc because the rage card does not support MODULATE4X. However this is not the cause of my problem, since it is still there when I let Irrlicht use MODULATE2X instead and lightmaps are being used.
I'm having what I think is a similar problem. I use directx 8.1. The LEvel is very dark in directX(no lights?) but it renders great in opengl , but in opengl it is extremly slow. I know that the slowness is probably my cards opengl support. But Directx is fast if only the lighting was correct.
yeah, im having a similar problem. my models in .obj dont work in DIRECTX8 (maybe its because my computer has directx9b?) but it works in opengl. i need to do on directx help me ?
