    It's crazy that moving data around 3D apps is still so broken everywhere. (but is changing that!) The last hour, I "just" checked some FBX export UV tiling/offset issues reported to me; Result: - 2 PRs (, ) - 1½ Bug Reports (, ) 😺👀

    Godot 4 opens .blend files by calling Blender to export a GLTF2 (Unity does the same but via FBX which is proprietary). If a .blend is found, it tries to autodetect where Blender is installed, otherwise you can supply a path. Props to and bruvzg for this code!

    Wrote a prototype for a Megascans -> GLB -> JSX exporter. It's a "one click" export from Quixel Bridge to get all the beautiful assets (you own) from your Megascans library into ThreeJS/React-Three-Fiber.

    My latest take is the “Metaverse” is a speculative design provocation catalyzing many important near-term XR interoperability efforts. Standards bodies & industry groups like have just as much if not more leverage for how it plays out. See

    You can now add glTF Settings node easily in shader tree! No more needed to create it yourself when you want to export Ambient Occlusion map :) (You need to activate glTF UI in addon preferences)
