I fear that unless the whole thing about restrictions is cleared up the Unreal Engine 4 becomes a no-go for developers from Belarus. Well, if only you’re not willing to move to another country along with your project. Merely lifting the access restriction to the website and downloads isn’t what is about anymore. Surely there will be some ways around to still use UE4 for toying and development, but I can’t think of a way to actually release your game project and pay royalties to Epic if you can’t oficially license it.
Let’s wait for a staff official position on after the investigation. I believe we need a definite statment from Epic regarding with sanctions/regulations/export restrictions/local legislation, and what’s even more important — some specifics on them. If there is indeed a legal restriction that prevents Epic to license its tech to Belarus residents (or Epic legal staff believes there is) — it should be backed up with some USA goverment document or something like that. I’m pretty sure there is no such documents, as (again) I’ve never been aware of any restrictions on software export of such kind to Belarus (except the mentioned encryption software). If we get to know what exactly forced Epic to take such approach to Belarus — then there is a that the whole thing will be cleared up.
