Thanks for your reply Flavien,
I know it’s a really weird bug but that’s how it is. I just came to the conclusion that using Datasmith and trying to update the project for other uses, in my case I wanted to have my VR project which works fine and a duplicate of this but with raytracing on, is just not possible. I can work on my existing project but if I duplicate it, turn off all VR options and turn raytracing on, as soon as I move the camera in the scene the PC restarts.
I re-installed Nvidia drivers, even on safe mode cleaning old ones and making a new fresh install and I used two PC’s, same happens. Datasmith is the culprit as if I go into a level with no Datasmith actors computer doesn’t restart.
I’ll try to answer your questions the best I can:
Can you give more details on how it restart? Are you on windows? do you get a blue screen?
I open project, loads up, as soon as I move the view on the editor the view freezes and 2-3 seconds after my screen goes black into the bios screen, no blue screens. Windows.
Does it behaves the same if you work with other revit files or other content in the engine?
It just happens in this project which I worked for a long time and we wanted to have better quality renders
What is your Unreal version? Revit Version?
4.26.2, Revit 2020, using all proper plugins
How big are the scene you are importing?
That is not the issue. I have several Datasmith imported files into my main level and if I try one or a few the issue persists, if I go to a blank level or I import geometry from my content it’s fine. Problem comes after I Import ANY previously imported Datasmith actor into a new level and move the camera.
Could you share with us the log files you will find in your project/saved/logs/ folder
I gave up trying to use raytracing on the project and deleted the conflicted project. I will need to duplicate it and change a lot of settings to replicate the issue and don’t have the time to do so.
What type of computer do you have? how old is it? which gpu? how much ram? how much space on your drives? Are your OS and GPU drivers up to date?
With all due respect, I don’t tend to ask for help unless I squeezed all options from my side, twice or three times. There’s not a single problem with my PC until I turned this project to a raytracing project. Due to the nature of the issue I’d assumed it was a GPU issue but after replicating the same behaviour on two other PC’s I can say the problem is not the PC
What do you see when you monitor your resources in the task manager while editing your scene and trying to freeze the application?
I’m not trying to freeze the application at any given time, Unreal freezes for two or three seconds as I already said and just goes to a black screen. The task manager behaves as usually and processes are all fine, there’s no abnormality in that. The only thing is that if I keep the task manager open, I go into the project, and just move, the task manager freezes for the same period of time.
As I mentioned, I know for certain the issue is the Datasmith file or actors in the scene when raytracing is turned on. If I create a blank project and re-import the same file it’s fine, but I can’t just do all over again just to have raytracing on. Hope all of this information helps.
