Just started messing with the new “design live” rendering update and my existing drawings all seem to be very overly saturated. I started a new one and it dose not seem to be doing the same thing, just the ones I have already been working on. I have tweak the setting and none seem to be getting me into a spot where the images are even close to be usable. I do find interesting that I can catch the program in a spot, see attached image, where it looks a lot like what it used to, but then it updates the render to be the bleached out/washed out image this is just not really usable. I am running AMD 3800x / rtx 2070 super / 16gb ram / all loaded on an m.2 ssd.
Renderings created with the legacy engine required the more lights to be added to the scene in order to be well lit. Not sure if you had added additional ceiling lights in your previous kit files. EZ Render does not require as much lighting. Old kit files can therefore appear washed out.
