Irrlicht Engine

Since bump mapping can be implemented as a pixel shader, would it be best to implement shaders and have bump mapping become a side effect? Also i see 16bit textures being a problem for bump mapping as the best way to do it, IMHO, is to use 24 bit RGBA using the alpha as a bumpmap. Unless you are into the whole partially transparent bumpmapped texture thing. Is that even possible?

well, hopefully irrlicht will have shaders support sooner or later. however, i dont recommend them as being the only way for the engine to use bumpmapping simply cause not all video cards support pixel shaders. just MHO.

Agree on Cyber_Sneak i just got a GeForce 2 MX400. mine doesnt support the PixelShaders or any of the technologies implemented in geforce 3/4/5.

i also notice that my computer slows down when i turn the shadows on in the techdemo, and i think that its my GFX card as well.
