All new render engines appear to be tied more to newish graphics cards, so be aware of the hardware recommendations & don't have the minimum specification if you intend to work with a lot of polys.
For render engines, Thea Render
https://www.thearender.com is a distant cousin of Kerkythea & Twilight.
It's real-time rendering is very handy and has good proxy support along with compatibility with Skatter.
I use version 2.2, as it's the last one that could be bought rather than subscribed/rented.
Development is still continuing, but slowed since being bought over by Altair. Support is good, if a bit slow compared with Twilight.
Epic Twinmotion
https://www.twinmotion.com is perhaps better suited to architectural renders, with a massive library of plants and props. The Sketchup model has to be exported out to a format that Twinmotion can import. The quality of renders is dependant upon having beefy Nvidia graphics hardware, although the basic render engine can still provide decent output in the right hands. Getting expensive for commercial purposes, although still good value compared with the likes of Lumion.
