gLTF loader not setting BoundingInfo

Hi, I think I’ve found a bug with the gLTF loader. I’m using it through the AssetsManager and it doesn’t seem to set the bounding info object. I thought this might be related to this issue (although I don’t think I’m using gLTF 1 here), but setting IncrementalLoading to false doesn’t change anything. I’ve created a minimal example PG.

• Bug repro on playground: https://www.babylonjs-playground.com/#3QG2DZ
• Expected result: the bounding box should appear and getBoundingInfo().boundingBox should be set
• Current result: the bounding box doesn’t appear (presumably size is 0), and getBoundingInfo().boundingBox doesn’t seem to be set

Just in case, I’ve tried with another model (both exported from Sketchfab) and it’s the same.

By the way, just got started with babylonjs and I’m blown away by how well it’s built, the ES6 support, tree shaking, the overall state of the docs and example. Kudos! 🚀

This is by design. getBoundingInfo returns a shallow bounding of the mesh (i.e. does not include children). Since the code is calling getBoundingInfo on the root node with no mesh associated, it just returns all zeros. To get the full bounding of all children, call getHierarchyBoundingVectors.
