No, I don't have any relationship with developers of FStorm Render Engine, but yes, I sent them this message over facebook because I appriciate small but high quality programs:
"Please write your email address on your website to make easier contacts, and please open a twitter account because in twitter #FStorm hashtag is rocking!"
Than since I'm new member of Steemit, I decide to share this program over here to let good community see how small render engine can be alternative to big competitors such as VRay.
They do offer free trial, and their final product licensing is on basis of monthly 20€ payment. Monthly payment style transactions benefit both for user and developer, since it provides understandable consistent income for developer to keep on proper updates, and it makes user to not "fully commit" to a product that might turn out to be bad deal in future.
I hope that, with the increased attention to the product, developer can update and upgrade it more often. It is sad to see last blog post from February 2017.
