Hey everyone!
I’ve been informed that the Inventory System is officially (this time) on the marketplace!
Sorry for any inconvenience caused and thanks to Epic and for resolving it fast enough!
Yes, skinning the HUD should be easy enough if you know just a bit of UMG.
I mean the code for the sub-widgets and functions exists and depending on what you need changed you can either keep everything, copy or remove the corresponding code
The HUD is a simple example of a skin the inventory has created (by a non artist 
) for displaying the capabilities of the underlying code! You can probably remove it fully too if that’s what you need!
About the 4.7 update now, we’ve run into some issues since auto-converting leads to some disconnected pins (that disconnect on every reload if you fix them)!
We’re working on fixing this and expect an update as soon as this technical issue is resolved!
Thanks again everyone!
