First attempt with Eevee (which required hours of work hooking up nodegroup inputs to values, and I probably even missed a few) based on a Cycles setup. I showed the 3 minute render to a college and (although I can spot other things) the only thing he really commented on was the bad aliasing artefacts on the floor:
Note that windows have blinds (it’s a projected screen cinema setup, so it makes sense to have ti dark/light controlled), so world is not hooked up.
These are the Render settings:
And these are the Preferences (system):
So a lot of things are upped from the defaults with no apparent effect on the aliasing. What do I need to do to improve this?
Note that this is my first attempt with Eevee (I used to get crashes within 1 minute), so I have no idea if probes/materials are well setup.
