Why are there no C++ Plugins or Game Templates in Market?
As far as I know, the Marketplace is not currently geared for C++ plugins. I think Epic is working on adding support for it … this is off-hand. 8-}
Hi,
C++ based stuff is currently not supported on the marketplace, and there is still no timeline from Epic for this.
Unfortunately, i have to say, i got quite some coded stuff i could put on the marketplace 
Cheers,
