Looks good.
I tested and some files were not opened or atleast properly but for now it is good to be merged.
Thanks for your effort and time. ❤️

@saw-jan could you please provide files which fail to open? I would like to investigate on it.

it was just too big that's why I was not able to see it at first. But I will send you the files

[saw-jan]

Here is the model that was too big and only visible when rotating. Also, there's some problem with auth
Mclaren.zip

@saw-jan Thanx!

Model size
we could think about re-scaling the model on the fly if suitable and/or get rid of hard coded min and max orbit distances

File size
when it comes to support different types of 3D standards we are going to face rendering limitations by the browser or better to say the underlying hardware resources and the support of theme (os depending), pretty soon (keywords: webgl, level of detail, shading, lights ...). Even if a huge file could be loaded into memory, this does not mean that the performance of rendering the scene will meet the user's expectations.

Auth Issue
[CONFIRM] It's pretty strange facing auth showing up on loading the model you provided. Did not notice something like this on any other model. This is maybe FBX related, but I am not sure. Still investigating.

@saw-jan To come to an end. It looks like missing materials/textures. Even Blender is blaming about ;-)

yeah, there're a lot of tradeoffs to consider. we can only try to minimize them.
