Hi, guys! I have been playing with Babylon.js for the last week or so and having so much fun!! Though, I am having a trouble looking for my object every time I load a different one. This example on Babylon PlayGround is somehow at the origin (0, 0, 0) and its scale is beautifully appropriate. Ho…

If you have an app where you don’t know which object will come in, and in what condition, or even which format it is, you could utilize boundingBox of the object. Specifically, you would calculate bounding box from every mesh in the scene, and you will find the center point of the object/structure …

hi @DOEHOONLEE there is something about that mesh. I’m turning my computer off now, though. I would try loading it in the scene explorer to learn more what is going on. I can’t see it right now why it’s not working, but this code I’ve used in the past for scaling - maybe it helps a bit (you can …

The simplest way for all such models is to open it in some 3D editor like Blender, then set mesh origin as you need (one may add scaling to taste).

Hello there ! I’ve encountered some similar issues when trying to import .glb files I created with blender. When you import a file, even if there is only one mesh in it, you’ll get an array of several meshes (called task.loadedMeshes in your case). I’m fairly new so I don’t exactly know why, but B…

[image] Faber: Also this kinda is my first reply to a dev forum so if anything’s not clear or just sounds wrong about what I said, please tell me Thanks for that!

i personally remove the root mesh objects of all my loaded .glb files because I hate them as well. We need to do a democratic vote and send the results to Khronos Group because I simply cannot for the life of me even fathom even once good reason my. " _ root _" for every mesh … no thanks.

[image] shaderbytes: We need to do a democratic vote and send the results to Khronos Group Nothing to do with the Khronos Group. [image] Does a glb have to come in with a __root__ node? Questions We need it because it conveys the right to left hand conversion

That sounds like a very nice and convenient way!! Thanks!! :slight_smile:

Woah~!! What a thorough explanation! Since I am new to Babylon, this seems very confusing for me at this moment though. Let me try your way and I’ll get back to you again. It might take some time xD Big thank to you!!

Some of the obj files I downloaded from sketchfab did not have root mesh and the arrays length were 1 only :frowning: Is this possible?

Yes. A single mesh is not uncommon for .obj files :slight_smile:

How do I have my obj loaded properly centered at 0,0,0 and scaled?
