Hi all - im importing a variety of 3rd party GLBs where i don’t necessarily have control of the creation of the file. Many have their assets way out in space. Like this crane - which is way outside of my skybox even though i’m importing its container to 0,0,0: [Screenshot 2023-03-17 at 1.54.56 PM] …

OK, I can hereby now confirm that this solution works (and is actually ez once you know about it). However, from my readings in this forum and the look at the PG examples from the API when searching for ‘getHierarchyBoundingVectors’, it seems to me like I’m not the only small brain :brain: …

@mawa you can run transform across all the assets in bulk with a shell script. Here’s that script - with a few of things ive run commented out. Just drop assets in a “source” dir and run the script - and they’ll end up in “output”. I’m really loving this transform library. Im thinking that when some…

[image] jelster: I think I noticed in your PG’s that you seem to be using the “root node” to position. Oh. Yea, which node should i be using to position? ^? Maybe i’m using the root node incorrectly in general? Maybe that’s what’s causing this odd gizmo behavior too? That gizmo correctly mod…

[image] bigrig: you can run transform across all the assets in bulk with a shell script Well, thank you. I guess I will have to give it a try. I was just hoping it would not be needed. To be honest, there are some things I do not fully understand. Like why can I normalize my asset to a unitcu…

[image] jelster: an alternative; it all depends on your needs As exposed above, I would rather have it ‘an alternative’ than ‘an extension’. But that’s just ‘lazy me’ :sleeping: I suppose :grin: Thanks for your time anyways and have a great day :sunglasses:

How about this solution by chatGPT? Yes, you can programmatically reset the GLB to the center of the world by using the Mesh class provided by Babylon.js. BABYLON.SceneLoader.ImportMesh("", "path/to/your/glb/file.glb", "", scene, function (newMeshes) { // Get the bounding box of all the meshes i…

While not a terrible solution, it may have a potentially serious drawback of introducing side effects; you will want to check that MergeMeshes doesn’t mutate the original meshes for this to work properly

[image] bigrig: Maybe i’m using the root node incorrectly in general? Maybe that’s what’s causing this odd gizmo behavior too? That gizmo correctly modifies that sword… but it’s all askew after initial rotation. The gizmo doesn’t follow the meshes around. Something to check is that you’re exp…

Great discussion here, but I had to post just to point out that the title is the best ever: [image]

:sweat_smile: Me: He told me “Bring the Crane in from outer space” … GPT3: I would need to find a way to get a crane from outer space. This could involve launching a rocket with the crane inside, or finding an existing crane in space and somehow retrieving it.

I’m glad the problem here is easier than that :rofl: I bet aerospace engineers would love to just be able to set crane.position = new Vector3(0,0,0) :stuck_out_tongue: (now that I think about it, would (0,0,0) be the center of the earth or its surface? :thinking: )

No, it doesn’t. It does only half of it. It doesn’t center the axis.
