I do the same making an Mesh Light Sphere and I too cannot complete a render even when the Samples of the lighting is set to 16 and low quality Render settings. It is part of the memory issue some of us are having. I can render out the exact same scene with DS220.127.116.11 RC2. It was one of the scenes I used to test the latest versions.
I wander if this is graphic card memory problem or computer memory problem , 8 RAM need to be enough for this kind of render.
when I try to render scenes who are more complex with hair , clothing ,and even one complete world loaded to the scene all together I’m not getting any crash .
I noticed that this crashes happens only when I start changing the Map Diffuse. or other Maps and textures I apply to the surface of my objects in my scenes
I was told by support what making this crashes Is I use older version of Pwsurface , but I updated to the latest version long before this crashes ever happened -so this something else . wish I know what . My guess is there are still old files of daz were not uninstalled properly from older versions who probably still creating conflict in my system. I have no idea where or how to find them and remove them .
anyhow at least most of the times it works ok. and when I use UE and changes the maps of it it works ok and no crashing . so for now i’ll stick to use this .
