3D models now work in RPG Architect's engine via glTF (gltf or glb extensions). This is a "stable" preview version (tried several different workflows). Complex, animated models without bones are not supported. Materials are generally not supported. I'm planning on supporting bones, but otherwise, support normals/vertices/color/textures (which should work) -- and eventually animations. I'd like to potentially get a preview of models in the editor at some point, though it's pretty low on the priority list at the moment. There have been a number of bugs/feature requests that have been building over the past week or so that I'd like to try to trim down a bit. Apologies for the lack of updates, but this one is a [b]BIG[/b] one.
