GtkRadiant render error - textures not showing up

Post by **Ryodox** » Wed Jun 20, 2007 2:12 am

I open GtkRadiant (version 1.3.7) and all of the textures appear solid white, in both the 3d camera view and the texture queue below it. I'm using Windows Vista, and an Intel video card (Intel(R) 82945G Express Chipset Family), with the latest drivers. I've tried switching between 32 bit and 16 bit colour, to no avail. Any idea why this is happening and what may be causing it?

(I've also tried version 1.4.0, but it kept giving me a critical error whenever it loaded. I uninstalled that and installed 1.3.7, which works fine, excepting the texture issue.)

There's a similar situation just a few posts down. Did you read it?

Yeah, I saw that, but I'm using GtkRadiant to edit Q3 maps, not the Doom 3 or Quake 4 editor, so I'm not sure how I could apply those solutions to my case.

Let me add that this occurs in 1.3.7 and 1.1.1 RC3. I've tried both of those along with 1.4.0 and 1.5.0 (the stable release and the latest nightly), but 1.4.0 and 1.5.0 both give me critical errors and crash ("runtime error: GTK+ error:GtkGLExt-WARNING **: Cannot create GdkGL context").

Have you tried running it in compatibility mode?

Also from qeradiant.com:

Special note for Vista-users:
You have to disable the desktop-styling in the properties of GtkRadiant.exe! In case of wrong menu-rendering you can switch to the "Raleigh" gtk-skin.
The gtk-theme can be changed in [install-folder]/etc/gtk-2.0/gtkrc.

Yes, I've tried running every version in Windows XP compatibility mode. GtkRadiant 1.5.0 and 1.4.0 invariably crash, even after disabling desktop styling, using the Raleigh skin, and installing it outside of Program Files. 1.5.0 gives me this error:

:\main.cpp:186
runtime error: GTK+ error: GtkGLExt-WARNING **: cannot create GdkGLContext

----------------

Stacktrace is disabled in release-builds

I also get alert windows with similar messages.

GtkRadiant 1.1.1 and 1.3.7 are the ones that seem to work best. Gtk 1.1.1 displays the textures in the 3d view window (albeit with the ATI render bug, on an Intel card no less), but textures all show up blank white in the texture menu. On 1.3.7 the textures show up white in both the 3d view and texture menu.

This error message shows up in the Windows error log when GtkRadiant 1.5.0 crashes:

Faulting application GtkRadiant.exe, version 0.0.0.0, time stamp 0x45eb3119, faulting module libglib-2.0-0.dll, version 2.12.9.0, time stamp 0x45ad7e2a, exception code 0x40000015, fault offset 0x00024b6e, process id 0x1218, application start time 0x01c7b3a9bbbd2218.

Any ideas?

It's going to be an OpenGL error (the clue is the mention of 'GL' in the error messages), which means your graphics chipset isn't up to the task; Radiant make serious use of OpenGL so you do need a decent supported card otherwise it's not fun

Yeah, I figured it was an OpenGL error, but the thing is that I can run Quake 3 with no problem, and my video drivers are the latest version. Besides the GtkRadiant crashes (1.4.0 and 1.5.0) and camera render problems (1.1.1 and 1.3.7), OpenGL seems to be fully supported. I don't get it. :icon8: I really have a mapping itch, too.

It's probably more likely the way Radiant is referencing OpenGL for use, it does do some 'odd' things, not much help I know but certain GFX cards were notorious for render errors, some of the early ATI cards caused endless problems hense that 'bugfix' in preferences.
