for some reason at random times (and when exporting) i get this error anyone know a fix

Recently I've been running in to this error for the past few weeks that just crashes my SFM at random. I've heard that it's related to memory leaks, but as of yet I've been unable to find a fix for this.

If anyone knows a fix please let me know.

I was working on a artwork for a few days and was rendering it out. After awhile it displayed the message "CUtIRBTree overflow error", and after searching it up, this error relates to running out of

Hi there, I have not been able to get in sfm for the past 3 days because of this engine error. So when I started up sfm it would ask if I wanted to update existing addons, which were a few widowmaker models. When I would accept it would freeze for a few seconds and then this error would come up. So far i've revalidated the cache, and revalidated 20000 files. After I revalidated, it disabled my scenebuild folder, and it still crashed! I unsubscribed from the widowmaker addons, and went into the sdk to put workshop on the highest priority. After that I had a whole lot more overwatch files to update, and I still got the error.

I read a bunch of posts here saying that you should remove some workshop addons to get this fixed.

However I've tried deleting my workshop folder multiple times and then only downloading a few or NO addons when you get the prompt on startup in sfm. But ye I still get the error while rendering. I used sfm for the first time in a while yesterday and didnt have any problems. It was today it started happening after downloading 1 addon with a bunch of eye textures, which i deleted later.

any help is appreciated

edit: seems like it could have something to do with too many override materials also, only had 3 overriden materials tho but i tried removeing 1 of them, waiting for result

edit 2: it worked when i removed override materials from my scout mdl model. Id still be gratefull if someone could explain why this is the case, would I not have this problem if I used hwm models?

i'm confused why does it say it's overflowed

I have recently started to have this problem with SFM and it is stoping me from
instaling anyother Models / Assets.

Any advice would be useful. Thanks for reading and post your thoughts...

*Edit. Just uninstall some ♥♥♥♥ you lazy ♥♥♥♥♥...

I was rendering a poster when this error message poped up. Now I have been searching for what may have caused this and it seem to be one certain texture. Please note that this texture isn't a custom texture. Has anyone else experienced this? And if you have, what did you do to fix that texture?

Every single time i render a specific animation i get this error. It happens at the same time in every render attempt and Ive revalidated my cache files and removed a few workshop models from the animation as well as restarted my computer. Any idea to fix this?
