I made a all in wonder post so I don`t use too much space,the enigmas as as folows: 1)What must you do to get out the black part of the texture and/or make it transparent(I found a Delphi source but it`s no use...) 2)Does anyone have a bump-mapping tutorial link that has implementations for arrays ? 3)I want to some stuff per-pixel...I got some combiners to work but there are 2 types of code(combiners coding),one that works and has textures with inverted colors,and one that doesn`t work and beside being from nvidia.developer it doesn`t even display Anything,it`s like it`s crashing the whole thing... 4)Can you get anything like lightmaps/shadowmaps out from 3DS max ? (if you ever used/heard/know of that) 5)Did anyone heard/knows of/using GlossMapping ? I`ve seen it on that NVidia "thing",it was stupid yet interesting... 6)What`s the difference betwen gl(something),and gl(something)ClientState ? (Ex: glEnable(),glEnableClientState(),etc->see gl.h for more...) There you have 6 enigmas...I`ll try to figure out more...but these should be enough...

1) Go through each pixel in bitmap, for every black one set the alpha channel to the value you want to mask off. Set the alpha value for every non-black pixel to some other alpha value. Use alpha testing or blending (depending on exactly the effect you want).

2) Got no idea what this question means.

3) What video card do you have? Not all of the techniques and extensions are supported on every card.

4) Not directly, max does compute shadow maps for rendering but I don't think you can extract them. You could right (EDIT: lol, I'm drunk, I mean write ) a plugin to compute light/shadow maps.

5) Gloss is a kind of specular 'smoothing', although the exact implementation I don't know.

6) Go to opengl.org grab the OpenGL specs and spend a week reading them. Alternatively, find the 'red book' online, I'm sure it has the answers you seek young jedi.

I would help ya, but reading six topics at once is giving me a headache.

At least seperate them into "vertex array" and "non-vertex array", and try to keep it one topic per thread. :-P

3) Max 5 supports Texture "Baking" which is what you are attempting to do. You can render and save shadowmaps, lightmaps, ect of objects in the scenes. The earlier versions don''t have this feature.

Gloss maps specify which parts of a per pixel lightened surface are shiny. So say youve got a texture that is half wood and half metal. You could make a gloss map that just lets the metal look shiny
