Setup an empty 4.27 project. Initialized TrueSky. Added a widget with a slider that adjusts time of day by dragging the slider. When in play mode, almost immediately when dragging the slider, UE crashes with the above error. Tested on multiple hardware/machines, and the same behavior. I have included a simple project to showcase this. Ive noticed that it happens a lot faster when rendering at 4K resolution.
Any ideas as to why this is happening? Download link to project – https://drive.google.com/file/d/1dg_9OfI5VlkDwXHECHu7IjNJQs03iU3w/view?usp=sharing

Hi Norbet, we can confirm there is an issue specific to DX12 at higher resolutions. We are working on a fix and will have it available with the next plugin release.
Thanks,
James

replied 3 years ago James, thanks for the update. Do you have a rough estimate as to when the next release is going to happen?
I would estimate before the end of the month, apologies I cannot give a more accurate timeframe
Thanks,
Hi, for a temporary workaround if you either switch to DX11 or remove the cosmic background texture, you should not experience the crash.
Thanks,
James

replied 3 years ago Hi James,
Thank you so much for the update. Given we are using RayTracing switching to DX11 is not an option for us, however, i’ll try your suggestion on removing the cosmic background right away. Thanks 🙂

Made the change you suggested, removing the cosmic background. Been using the application for 5minutes, we are no longer experiencing the crash. Thank you for the help.
Hi Norbert,
I am investigating this now.
Best Wishes,
Andrew
Great, thanks for all your help Andrew. Sorry for the many questions, we are evaluating the plugin and would like to make sure it fits our needs before purchase. Just a few issues we need to work out 🙂
