MC suddenly turn blackout when playing

[B-Wither]

When I play 1.19.2 forge, it suddenly black (more like grey) out and then server shut downs. I saw log and it was written like this.

[hammertater]

Thanks for sharing the log. Do you remember what you were looking at when the crash happened? A tree from a mod, a building with leaves blocks, etc.

[B-Wither]

I am not sure to be honest. Maybe there was chests with labels from other mod, but as I see log when blackout happened, it looks like due to this mod...

[hammertater]

Yeah, it’s definitely caused by TreeChop - the log is very helpful! I’m just looking for any info on how to reproduce the crash so I can figure out why it’s happening and fix it. No worries though, I’ll look into it

[hammertater]

Could you share your mods list @B-Wither? Maybe upload your whole "latest.log" file, it's ok if it doesn't include the crash

[B-Wither]

latest.log Here is.

Hi, I ran into similar behavior in 1.20.1 when looking at an apotheosis tower (in a spruce forest, it has a special wooden skin) Here is the log : [17:58:45] [Render thread/ERROR]: Error rendering

[hammertater]

Hey, thanks a bunch! I’ll see if I can reproduce the error

[hammertater]

Couldn't really fix the error as of 0.18.5, but I think I've stopped it from causing crashes. Sorry for the wait y'all! Please reopen if anything bad still happens - I never actually managed to reproduce the crash.
