How to prevent Blender from crashing when running out of memory? I'm waiting for like 5 minutes for a render to start, nothing happens (Blender 2.90.1) and Blender is crashing in the end. I already tried to render the project using Blender 2.83.8 but I'm getting the same issue. As you can see from the screenshot, I'm running out of memory since I only have 16gb RAM and it's showing me that blender is using 20.34gb. The viewport is fine however, I can see the image resolving and everything...

Q: Is there any chance to render my image although I don't have enough memory?
If you are out of memory, the only solutions are to install more RAM in the computer, or to make the paging file (virtual memory stored on disk) in the OS larger.
Or work in scenes that do not exceed the resources available in your computer. Don't abuse the number of particles, use instances instead of duplicates, use modifiers and set subdivision surface to low values Blender render crash when using subsurf modifiers.
