Hi Götz,
actually for testing went down to pretty minimal picture sets - like 60, where I previously completed projects with more than 400 successfully.
I don’t believe there is a hardware problem - it’s a solid, recent Alienware notebook that should be good for that task and handles similar intense jobs without issues.
I so hope in the end it’s not some stupid thing I am doing wrong - otherwise, I owe all you guys big time for causing so much fuzz 
but I am really clueless by now
I can understand your frustration.
You’ve certainly tried a lot! But since that didn’t get you anywhere, it might make sense to widen the radius a bit. Since it worked fine for Zuzana with one of your own projects, it’s hard to imagine that RC is causing it. And hardware does break sometimes…
I bet you did a reset on all the settings, right? I would try and uncheck the graphics card and then re-activate it, maybe after exiting RC. Did you un- and re-install yet?
Hi Götz
Totally agree - its probably some weird edge case - however: a crash is a crash.
I tried everything you suggested - just reinstalled and am trying again. (I reset the cache position to system default - one thing I changed)
So: there is still hope
and again: thanks to all for the support
Good luck! 
Thanks Götz - however the problem stays with that dataset.
Started from fresh , simplified to about 2 mio tris - crashed at something between 50% and 70% texturing.
I was able to do some other model though

So - I would assume it’s some edge case between the dataset and my configuration or something.
I would highly appreciate to get some feedback from the numerous crash logs I reported (some of them I linked to this thread) - maybe that would give further clues.
If I get some info about what I ‚did wrong‘ that causes the crash then I could avoid that in the future.
I hate to be such pain in the ■■■ - but right now I can’t help it
Hey Heiko,
don’t apologize, that’s what the forum is for! 
It would be interesting to know which component is used at the time of crash - did you monitor that yet?
Hi Götz
this is what I get from my last test - again: texturing is rushing towards 50% and then it either crashes or it get an operation failed.
Seems not to have anything to do with simplifying before - just texturing does not work.
As you can see its only about 85 photos - so it really should not be an issue with 16GB ram and 8GB video memory ?
just to close this topic:
it finally works for me
I deinstalled RC, deleted all directories and conf files and caches I could find - now it seams to work well again.
So: definetly something on my side - however I still believe it would make sense to track this thing down - if only to give the user a better hint what exactly goes wrong and how to make it better.
Anyways: thanks to all for your support suggestions.
Hi Heiko,
thanks a lot for reporting this!
I am not so certain that it was caused by you.
It might just as well have been some corrupted file or an error in the registry…
Anyways, glad that it works again for you!
