Thanks, Taylor.


Well, I've updated and fixed Texturing in Wiki. There were several places with wrong info about env because of my "un-knowledge".

Please, somebody check that everything is fine now.

Nicely done, ARSPR.

Careful, though. May have to change your "Title" to "Preys on Mantis, Stalks on Wiki"

No?

"Crouching Mantis, Hidden Wiki"?

okay... very specific question time... which shaders are used when the model is viewed with no diffuse, no glowmap, no specular, no normal, no env map flags in the ship lab?

(in other words, when only light is applied to the ships bare polygons...)

l-v & null-f

l-v & null-f

Wikified.

And then it makes me asking another question. If null-f uses l-v, when would null-v be used?

I think that I don't really understand the difference between null and l  . My answer for pecenipicek question would have been l-v and l-f.

Could you explain me the difference between null and l, please?


EDITED...


I've checked in mv_core that there's no l-f shader. So although my previous post is more or less fine, now I think that:

• There's no l-f shader because, if lighting is enabled over texture effects, you need to use at least one effect. So l*-f always need something (b, g, s, whatever). There's no point in a lonely l-f shader.
• If null-f uses l-v, when would null-v be used? (I've verified that it exist in mv_core.vp)
• OTOH, there are also b-v, b-f, bg-v, bg-f shaders. Where are they used?
  

Please, could someone explain it?

"null" is empty, so null-v is no special vertex effects like lighting or mapping, and null-f is no maps in use.  So in the lab, if you turn off all maps and leave lighting enabled, then it would use l-v (for lighting support) and null-f (since there aren't any maps).  If you turn off lighting and enable at least one map then it would use b-v and b-f (or bg-f if there is a glowmap).  The b-v/b-f/bg-f shaders are really just used for the models shown in the hud target box.

And bg-v is just a packaging mistake, it's not used by the code.

Wikified again in http://www.hard-light.net/wiki/index.php/OpenGL_Shaders_(GLSL). Please check. I think this is the last time 

And bg-v is just a packaging mistake, it's not used by the code.

Made one minor correction: The coded number of supported shaders (ATM) is 66, not 67. The MediaVP shaders currently have a miscellaneous orphan file.

I suppose I've "found" the extra file

I added a listing of the V to F shader sets.
