Try disabling post-processing and see if you still get this error; I tried to set it up so that it wouldn&#039;t even compile any code involving gl_FragData if you disabled post-processing.
====== tlh2000 (2010-05-06 14:34:57) ======

the point is that we should somehow detect that gl_FragData isn&#039;t supported - i thought we would do that by checking the frame buffer stuff in the R_InitExtension function - but a) this is not enough or b) it is not working as i thought it would work ;)

the fx cards from nvidia aren&#039;t really good cards - so it&#039;s likely that they don&#039;t support all the needed features - we just have to detect this somehow.
====== arisian (2010-05-06 17:36:45) ======

I think I&#039;ve figured out which extension we&#039;re not checking for; I&#039;ll fix it later today.
====== tlh2000 (2010-05-06 18:05:11) ======

cool - thanks a lot
====== arisian (2010-05-06 21:13:42) ======

try r29774, and let me know if that fixes it
====== tlh2000 (2010-05-07 05:48:30) ======

very nice - i don&#039;t have a nvidia fx 5200 here - let&#039;s see whether the reporter comes by here and comments on it - set to pending.

====== arisian (2010-05-09 23:34:38) ======

Is that last error only with postprocessing enabled, or always?
====== *anonymous (2010-05-10 17:50:08) ======

Hi, I&#039;m the original reporter. I&#039;m now using r29790. With glsl shaders off, everything works well and none of those errors show up. With glsl shaders on, everything works well but FPS drops somewhat, all those errors show up, and this error shows up in the log repeated 10-20 times each second:
2010/05/09 22:45:00 R_ProgramVariable: Could not find GLOWSCALE in program geoscape.
(C:\UFOAI\UFOAIwin32BUILDenv\MinGW\ufoai\src\client\renderer\r_sphere.c: line 266)

So if glsl shaders are on, all the errors show up even with post-processing disabled.
====== arisian (2010-05-11 00:52:05) ======

Oh, this is on the geoscape? I thought we were talking about the battlescape. The geoscape uses a totally different rendering pipeline; I&#039;ll take a look and see if I can figure out what&#039;s going on.
====== edirr (2010-05-13 10:04:04) ======

I don&#039;t know if it&#039;s related, but in revision 29838 I&#039;m getting a seriously screwed up geoscape, with everything going extremely bright when GLSL shaders are enabled.

Shaders off everything works fine, but when enabled, everything is screwy. It looks like it could be related to this, or it could be a separate issue. I&#039;m compiling the newest revision right now, so if anything does change, I&#039;ll comment on it.

====== arisian (2010-05-13 13:06:17) ======

Is "postprocessing" enabled or disabled when you see this problem?
====== edirr (2010-05-13 14:37:05) ======

Postprocessing is enabled. The entire geoscape turns intolerably bright and all objects and effects disappear from the globe. When it&#039;s turned off, geoscape is okay even if the shaders are on. Now using revision 29887 and the same problem persists.

While we&#039;re on the subject, ATI Radeon HD4870 still gets all models on battlescape solid black if shaders are enabled at all, but that&#039;s related to another tracker item. Figured I might as well mention it here too, since both it and this geoscape issue are shader/postprocessing problems. I&#039;ll upload a screenshot later.
====== edirr (2010-05-13 15:40:17) ======

Seems I can&#039;t upload a file to this item, so I&#039;ll post it to the forum instead. With revision 29887, the error messages in ufoconsole.log are somewhat different from the ones in 29838.

That same error repeats some tens of thousands of times. Does this merit a new tracker item?

I posted a forum thread with the screenshot at http://ufoai.ninex.info/forum/index.php?topic=4799.0

Did you re-start UFO:AI after enabling post-processing? It sounds like the non-postprocessing version of the GLSL is getting used with the postprocessing version of the C code, which can happen if you switch the postprocessing on (or off, though that&#039;s not as bad) without re-starting the program. Probably we should force re-compilation of the GLSL code whenever these options are changed, but that isn&#039;t being done yet.
====== edirr (2010-05-13 20:14:35) ======

No, actually I didn&#039;t. Justtried it now and restarting after enabling the shader post processing eliminates the problem. Looks like you&#039;re right about the cause of it. Your proposed solution would certainly do away with it for good. For now, a mouseover tooltip about requiring restart for enabling them would probably eliminate spurious bug reports.
====== arisian (2010-05-13 20:58:59) ======

Yeah, sorry about that; these new features aren&#039;t totally polished yet. I haven&#039;t really looked into how hard it would be to re-start the rendering system when options are changed, but it must be possible, since it gets done when the resolution is changed. In the mean time, I&#039;ll add that tooltip ;)
====== tlh2000 (2010-05-26 05:29:54) ======

what is the state of this tracker item? the restarting of glsl when changing glsl-related cvars should be fixed - but what about the compilation?
====== arisian (2010-06-11 13:20:18) ======

So far as I&#039;m aware, everything in the 2.3 branch should compile. Since I&#039;m not the one who&#039;s been reporting problems, though, it&#039;s hard to be sure.
====== tlh2000 (2010-06-19 06:39:31) ======

will close this now - my card is just too old - and it compiles fine on newer cards now
