Hi Flavien,
Thank you for helping me with these issue and taking the time trying to replicate it. I will try to give you some more information regarding this bug.
I did used DataPrep to import the Datasmith files, the thing is that I imported about 7 different datasmith files from Revit and some of them were re-imported a couplke of times due to changes on the original file.
What I meant by what I said is that if I create an empty level and just move around doesn’t crash, but as soon as I add into the levels tab any level created from the Dataprep process and I move around the computer restarts, it doesn’t even crash it goes directly to restart. So I guess that would be your third option from the three you have me.
I do not use a laptop. I’ve got a Ryzen 9 with a 3080 and 64Gb RAM as working station and a Ryzen 7 with a 2070 at home, both do the same when I replicate what I told you and another computer at work too.
As I told you before, I gave up trying to set up the project for raytracing and GPU lightmass so I went ahead and did it like I’m used to and it works out fine. I just thought it would be worth mentioning to the community that multiple imports of Datasmith files and converting the project to raytracing could cause these issues and maybe should be adressed somehow. I’ve been working extensively with Datasmith since it’s beta release and I’ve found a lot of issues but nothing as major as this one.
