that is conversion rate about 1%, this is standard for similar services. Dropbox/gmail/Corona/... does not make money by convincing everybody who tries it to buy it, but by convincing millions of people to try it ;)
But the Corona 45 day trial doesnt take you 45 days to realize you want a sub. I've been doing CG stuff as a hobby for half my life and when I was playing with beta/trial, it was just so much easier to actual get renders out! Not having to tamper with render settings and interactive rendering makes it so much easier to adjust lighting and materials. The amount of renders I do for personal experience has easily gone up 3 or 4 times. And theres the price, which isn't gonna cost an arm or leg that sweetens the deal. So kudos on such a great rendering engine :D
I have a bunch of tables I modeled a few years back that I made new materials for, that are just waiting to be render. But with the new material library with Corona, it'll make things much more interesting now that people can just drag and drop those onto the models.
That's actually pretty good result - my free download to sell ratio is close to 200:1. No complaints though, if i wouldn't want that people download my models, i wouldn't put them for free. Sure, it would be nice to hear thanks from time to time, but i guess it would be quite tiresome to hear that 50k times :]
50k times... well hello mr fancy pants haha. Yeah 50k notification on nothing but thank you's would be a bit tiresome, to say the least. It would be nice to see the renders where your freebies are used in though, would be nice to see how others are using them. Ty to ivan777, attachment was a render where I felt i could use some green in the room.
