           Summary: multitexturing is messed up in quake wars (regression)
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: aaalmosss@gmail.com


With some detail levels only the base texture (diffuse) is drawn on the
objects, but no light/bump/specular. With 'Shader Effects' set to low the
strogg deployables are like this (from any distance), while setting it to high
makes every object (except the ground) that are closer than ~10 meters appear
like this.

This message is written to the console a couple of times:
Not a native swizzle: 00000e08

Can you run the program with the environment variable RADEON_DEBUG=fp and post
the output.

Verbose patch

This patch will give me some more verbose output, could you apply it to master
and post the output with RADEON_DEBUG=fp

As the previous one, this was also done with shader effects = high.

Thanks.  Running with RADEON_DEBUG=noopt should make the problem go away while
I'm working on a fix.

Possible Fix

I think this patch might fix this.  If it doesn't could you post the output of
RADEON_DEBUG=fp again.

Unfortunately the fix makes things worse. Now everything is black except the
sky, the trees and the weapon projectiles.

Fix v2 works perfectly. Thanks. I also tested some other games, and saw no
regressions.

Now this problem appeared again. With medium shader detail all human
deployables and the strogg AVT loose detail textures and lightmaps as
approached. With high shader detail the wheels of some vehicles do this as
well.

Can you bisect this?

    r300/compiler: Fix bug in rc_get_variables()

    Variables that write to the same source select need to pe paired
    together otherwise the register allocator might fail.
