My dungeon crawler now has an inventory with a rotating 3D model
spent 3-4 days on this and it finally works.
at first I wanted a regular grid inventory, but then I decided to add a rotating 3D model of the character on the right side, so it feels more alive than a static portrait.
also made a hand widget that follows the cursor, same as in Minecraft, items swap on click.
next I'm planning to add a player stats panel.
the game is called Plink Void, Steam page is in the comments if you want to follow the development
