OpenGL: invalid value from TwbRender.LoadGLMultiImage

[mrmalin]

as soon as texgen reaches gathering resources the ram and vram fill up in a matter of seconds causing the kernel to end the program. there are no logs for texgen created.

im running texgen through mo2 through proton experimental, here are some information about my system

i tested 194 with MaxMultiSamples=8 and MaxTextureSize=8192 and also 4/4096, then it drops an opengl error that i cant find on the forum. sadly i couldnt test with your testbuild you mentioned in the other thread about linux memory issue.

Whatever changes, new settings were included in the test version are part of the alpha versions related after that.

Read https://dyndolod.info/Official-DynDOLOD-Support-Forum#Post-Logs which TexGen log and debug log and bugreport.txt (if it exists) to upload for the OpenGL.

The OpenGL error should have a link "Click on this link for additional explanations and help for this message" as explained in https://dyndolod.info/Official-DynDOLOD-Support-Forum#Read-Log-and-Error-Messages that should open https://dyndolod.info/Messages/Exceptions#OpenGL, so read that.

Consider copy and pasting the OpenGL error message as explained in https://dyndolod.info/Official-DynDOLOD-Support-Forum#Copy-and-Paste-Text.

[mrmalin]

sadly no logs and the little information window just loops around loading infinite.

settings are 
MaxMultiSamples=4
MaxTextureSize=8192

every other one just fills up the ram and makes it close

 

<Error: OpenGL: invalid framebuffer operation from TwbRender.LoadGLMultiImage for textures\default_n.dds 2 2>

As explained in https://dyndolod.info/Official-DynDOLOD-Support-Forum#Post-Logs, the log messages you see in the message window, are saved to the log file when the tool is closed normally, which should still be possible after that error message. At that time it should also save the debug log. Otherwise enable the realtime log, as explained in the same section.

Is this already with the GLDebug=1 setting as explained in https://dyndolod.info/Messages/Exceptions#OpenGL?
If not add GLDebug=1 under [TexGen] in TexGen_SSE.ini and upload new logs.

Set MaxRenderResolution=4096 under [TexGen] in TexGen_SSE.ini as suggested in  https://stepmodifications.org/forum/topic/21027-texgendyndolod-out-of-graphics-memory-linux/

Test with a stable proton version.

Add LoadGLCompressed=0 under [TexGen] in TexGen_SSE.ini to see if that gets to the TexGen options window. Upload new logs as well.

[mrmalin]

ok, setting

• GLDebug=1
• MaxRenderResolution=4096
• LoadGLCompressed=0

gets me to the options menu (the little information windows with the loading bar pops up anyways).i can make my settings, run and then freezes the entire os, no logs produced.

this is the bugreport.txt

the same thing runs just fine on my steam deck, i guess nvidia scammed big time again with their drivers

That bugreport.txt has to be from runs before LoadGLCompressed=0 was set.
Delete old logs that you already uploaded.

With the entire OS freezing you mean Linux?

Test if you generate just stitched object LOD textures by not selecting the rendered object LOD textures and not selecting the tree/grass billboards.

Test with a stable proton version.

Read https://dyndolod.info/Official-DynDOLOD-Support-Forum#Post-Logs how to enable the realtime log in case the normal logs can not be saved.

[mrmalin]

yes, linux freezes as a whole, only way out is a hard reset by holding the power button.

heres the TexGen_SSE_realtime_log.txt of the crash.

[mrmalin]

this is with only stiched object lod checked:

• TexGen_SSE_log.txt
• TexGen_SSE_Debug_log.txt
• TexGen_SSE_realtime_log.txt

[mrmalin]

nvidia just pushed new drivers with only "bug fixes" in the changelog, let the fun begin again

[sheson]

The logs look really odd. If Linux actually crashes then something really bad is happening. If not the driver, then potentially a power supply problem.

when i have the time, maybe at the weekend, ill try on ubuntu. from my recent observation people with intel/nvidia setups have a lot of trouble on arch at the moment.

he was right all the time.

quick update from my side, i updated my bios and installed new nvidia-dkms 575.64.05-1 drivers, running texgen (mo2<-proton experimental) with these settings

• MaxMultiSamples=4
• MaxRenderResolution=4096
• LoadGLCompressed=0

seem to work fine although its pretty slow in generating files

Setting LoadGLCompressed back to 1 if things work should improve that.

Using Dyndodod 3 Alpha 194, Dyndolod Resources Alpha 57, and Dyndolod DLL NG Alpha 36.

This started happening the last couple of days. I was on an older Nvidia driver from a month or two ago and would get an OpenGL error some of the time, but upon re-running texgen, I could get it to successfully run to completion after one or two tries. I regret not saving the logs from the other day, but I no longer have them. Yesterday I updated my drivers to the latest version and now I get this error every time. The error never points to the same texture file and it always happens about 1 minute in.

I've tried using NVCleanstall to remove unnecessary bloatware, and completely removing my drivers and installing them from scratch. Nothing has worked so far. My next move I guess is to try to figure out what driver I was using when I could still get Texgen to finish some of the time, but I wanted to post here in hopes that there's a better solution. Thank you.
