I have downloaded the trial of indigo renderer and followed the steps to enable it in Sketchup however there is no ‘extension’ tab on the top nor is there an ‘extension’ tab in Sketchup tab, then preferences.
I have also tried opening extension manager and selecting install extension but when tying to select indigo from my applications it is greyed out.
I have Sketchup pro 2017 and am using a Mac OS X El Capitan.
What am I doing wrong?
