Haig and BBoyz, similar rainbow issues..

[Tumu]

Here's some screenshots from Tribes and GLQuakeWorld that could be helpful in resolving the rainbow textures issue with OGL ICD:

First, Tribes 1.9 with config/ClientPrefs.cs setting $pref::OpenGL::AlwaysRGBA = "True"; (Stronghold demo).



Trippy.

Second, same scene with $pref::OpenGL::AlwaysRGBA = "False";.



Third, GLQuakeWorld 2.33-0005 with r_dynamic 0 and gl_flashblend 1 (overkill.qwd).



Fourth, same with r_dynamic 1 and gl_flashblend 0.



See the pattern? If Tribes is forced using RGBA textures, it renders them with rainbows. And if dynamic lights are enabled in GLQuakeWorld, textures are rendered with rainbows. Maybe GLQuakeWorld renders dynamic lights on RGBA textures?

And here's one last shot from GLQuakeWorld (overkill.qwd with r_dynamic 0 and gl_flashblend 1) which I got when I ran GLQuakeWorld after taking those screenshots from Tribes. I had to reboot to get GLQuakeWorld behave correctly. Maybe the OGL ICD didn't reset itself properly after running Tribes or Tribes did something evil to the ICD.

I have a similar problem with Quake2. It's very weird, because I have newer heard of anyone one else experiencing this with Q2. It occurs only when coloured light is enabled.

There's a screenshot at http://TRsDomain.homepage.dk/quake_bug.jpg

The same bug is also present in HalfLife.

Use the REG Hacks and disable Palettized Textures. This has solved the problem for me.

Haig, J.B.?
Any Matrox info on this? Last time I asked, I was told that you couldn't reproduce the problems. Hell, even if you said "it's a problem with the way the games were coded for Glide", I'd feel a <I>little</I> better.

it's always hard to tell since this does not ahppen on all systems and with all configurations... even if they look the same... but yes paul is right, disabling Palettized Textures should fix it... for now.

Hi Tumu !
I've got the same colors in glQuake.I've allready disabled Palletized Textures but it's still the same. I've tried out r_dynamic 0 and gl_flashblend 1. After I restart glQuake r_dynamic is 1. Can you post the syntax for the shortcut of glQuake.What I mean is something like "E:\QUAKE1\glquake.exe -width 1024 -r_dynamic 0". Is this the right syntax??

Marco, if you put the r_dynamic 0 and gl_flashblend 1 commands into your id1/autoexec.cfg then they should be run everytime.

Wombat, GLQuake and GLQuakeWorld have always used OpenGL. 3dfx just made a MiniGL driver for their cards because they didn't have an ICD.

For the palettized textures issue, Tribes doesn't use them with default settings. You'll have to force them with config/ClientPrefs.cs setting $pref::OpenGL::NoPalettedTextures = "false";. And the issue here was that forcing RGBA textures gives the rainbows (not enabling palettized textures).

And as for GLQuake and palettized textures, why PD4.51 ICDb1 didn't produce rainbows? GLQuake was fine and dandy with ICDb1. PD4.51 ICDb2 and _all_ 5.xx-series have produced rainbows with same settings I'm using.

Tumu,

I have always had rainbows since the first beta ICD. I don't know why it doesn't happen for you. I am sure it will be fixed.

Hi Tumu !
Creating an autoexec.cfg with the commands in it works great.
