Hi! Unfortunately this is “out of our control”, as the packaging for the marketplace is done by Epic and not by us (e.g. our plugin does not depend on the HTTPChunkInstaller module). Anyway I can share the build instructions we distribute to the Gumroad users, they surely work: Unique Download Link | WeTransfer . There you’ll find the build instruction for the source distribution, simple version: make your project a C++ project adding an empty C++ class, copy our plugin as a “project local plugin”.
