Hi why time rendering in the new version is 5 times longer than the older version?
Hi,
I noticed the same behaviour of Renderin 3.
In my opinion, Renderin 3 has only one advantage: It is compatible to Sketchup 2016.
And this is the only thing. 
I would pay money, if I could use Renderin 2 in Sketchup 2016 
It’s important to know that the engine has changed
The settings used in v2 are not optimized for v3
If you compare the same sketchup file without any setting changes
It can be the problem
