Well UE4 game engine is great, but i do find the forum disapointing me. i dont think i ask for help ever again, i prefer cancer, i think i might cut myself off from this forum, without ruddness, i not good enough for this forum, well i got enough to keep myself busy, Blender UE4, and eventually UE5, but reframe from forum, also i have a market place i signed up for, to become a seller, now i see the truth, no one deserve, anything i sell in the future, a really good punishment, so this is a goodbye all the best to all, with all your game engine glitches, bonvoyage.

Can’t say anything about the marketplace as I hardly use it. The interface is sluggish, tis all I know but that says more about the launcher.
