I love Corona, and I was using it from almost 2 years in Blender 2.78/2.79. After changing to 2.8 Corona, even the free exporter written by Glen is something that I miss really much. Even tried to go back to 2.79, but 2.8 is much better optimized so i stuck with Cycles/Octane.
I'm looking forward for V-ray and Blender, but I am afraid that developing it isn't go so well. They wrote that they made it work, but didn't show any proof, screenshot. Only words. No Nightlies to check how it works.
Many developers were annoyed by changing Blender Api all the time, but currently with long term support it shuldn't be a problem? Right?
I think that Corona for Blender should bring many users from 3dsmax to Blender, because Belnder is becoming much more friendly software than 3dsmax. And if it will be possible to use proxies made in 3dsmax in Blender it shouldnt be so painful witch changing Softwares:) I miss Corona proxies the most in my workflow Using Corona Proxies saved me a lot of memory - for example two scenes one made in Corona and proxies and the second Cycles, which was even less complicated than this in Corona.
Everyday i see many people on Blenderartist forum who are making archviz. If Corona developers arent sure if it is a good place for possessing new clients, than you can make an topic there to ask how many of them should be ready to pay for working and official conection between Blender and Corona :)
