Need to hotswap object URL with automation, can a webGL build's script be altered?

[db1713]

So the tool does what it says it does but every time I want to load an object, I have to go into Unity or the script and edit the URL depending on object URL. However I want to load a 3D file (obj,fbx) into my webGL build which has some viewing tools, without preloading the url manually. The webGL model viewer will be used to open a bunch of different models, think of it like the Windows 3D Model Viewer which allows you to double click on a 3D file and it asks to open in the Windows 3D Model Viewer. My assets which need to be loaded in runtime will be stored in S3 buckets.

Any pointers are appreciated.
