System is running low on RAM

[Bjoershol]

Hi,

I'm trying to render a scene that I have worked on previously, that was pretty slow but rendered with no problems.

All of a sudden today I am getting this error - I have a lot of scatter objects and such, but disabling them isn't helping.
128GB RAM should be more than enough, anyone have any idea what's going on?

In task manager, Memory at 99% or 100%.

Reduce some of the image resolutions. You'll be amazed what a difference this can make.

I highly recommend using Pixamoons bitmap resizer, but Corona dev's will now tell you this is not necessary as they automatically scale down bitmaps apparently (even with this new feature I still like the pixamoon option).

It costs 18 bucks I think but it's been a LIFESAVER for me in the past and definitely worth it!

Thank you for the recommendation! I should look into it.

I found that the problem is actually one of the objects I've put into the scene, which for some reason crashing the program.

I opened it separately and converted from Physical materials, and it looks like it worked!
