Steam has recently comes out with TaleSpire. It is in Early Access but it is sort of a Tabletop Simulator specifically for RPG. While it is in Early Access there is already a lot of modders adding content to the game. I would love to bring your minis to the TaleSpire community but currently the easiest way to add content to the game is using OBJ/MTL files not assetBundles. Would you be willing to make your source files (OBJ? FBX?) available so that I can introduce them to the TaleSpire community? I would give you full credit for the source.
