Like every year - let the New Year be better for all of us and definitely not worse.

There are 11 unique characters in this session (1 shot in total) with 7 of them having full clothing and accessories. To get all of them into one session, multiple sessions has to be imported and props from shots transfered as even opening in-editor file browser or model browser resulted in immediate crash. Giving that SFM is 32bit, the only reason it was able to hold so many things and not just crash immediately after loading was because many assets are repeating. Without lights it was possible to render 1080p poster, however after introducing light poster rendering as impossible (crash or pitch black image). Rendering to movie only once succeded, but only in 720p with every odd image having false colors. The only way to get higher resolution was to make a screenshot of the Primary Viewport... if not for SFM to crash even when changing window layout or size. After many tries it worked and this is what you can see on the image itself.
When SFM is Out of Memory it won't let you go any further whatever you would try to do.
