Hello, it would be interesting if Corona had an option to start as the default engine along with 3ds max
Set up an maxstart file with Corona selected as render engine, and that’s done 
It is an alternative kkkkkk
If it’s only about setting Corona as default renderer, then there’s even better way - go to render setup>common tab>assign renderer rollout, set Corona as production and material editor renderer and press save as defaults button - no need for the annoying maxstart file :]
Haha true!
Since I did not think of this before !
Thanks kkkkkk
