I noticed today that after building a scene with only 388 vertices that Blender tended to crash while also causing my computer to freeze. However, it did not crash when rendering a more complex scene with over 92,382 vertices. The scene with 92,382 vertices also has a mantaflow smoke simulation active, so I am not understanding why Blender is struggling with a more basic scene. Both were rendered with the cycles engine using the GPU and tiles sizes of 256 by 256. The Blender Version is 3.0.1. The specs of my computer are as follows:

CPU: AMD Ryzen 5 3600x 6-core processor 3.80 GHz

GPU: NVIDIA GeForce RTX 2060

Baseboard Product: ROG STRIX B45-F GAMING

Installed Ram: 16 GB

OS: Windows 10 Home

Statistics of the High-Poly Scene:

Objects: 1/140 objects Vertices: 92,382 Edges: 177,456 Faces 85,879 Triangles: 176,881 Resolution: 500 by 500 pixels

Statistics of the Low-Poly Scene:

Objects: 1/5 Vertices: 388 Edges: 512 Faces: 157 Triangles: 434 Resolution 96 by 32 pixels

Unfortunately there is no crash log because my entire computer freezes when I attempt to render. I tried closing any other apps and rendering the scene, but that didn't work. I got rid of any materials that were not being used and rendering it, but that didn't work. Finally, I tried making a new project file and bringing the objects in and rendering it, but that didn't work. If anyone can shed light on this issue that would be greatly appreciated.

    $\begingroup$ Is the crash tied to the specific blend file or the model itself? Have you tried rendering the same model in a new project? $\endgroup$

  • $\begingroup$ @Jakemoyo definitely the model itself, I tried to import the model into a new project and it crashed. $\endgroup$ Commented May 12, 2022 at 20:49
