I have a blend file with a number of meshes, stored in different collections. I would like to keep that hierarchy when exporting to GLTF, with the collections as THREE.Groups. I am aware that Collections don’t transfer. When adding an Empty (let’s call it container) and parenting the Meshes to it,…

Right so the problem here is that GLTF is already using parent/child hierarchies to bridge differences between modelling software (1 mesh + multiple materials) and GLTF (1 mesh = 1 material). There is an additional constraint with GLTF in that, if it is performing quantization of the vertex format……
