In our project, users can import files from a cloud/storage using a webDAV filepicker. On import, we pass the received and parsed blobs as File objects to our component hosting the Babylonjs scene. We implemented some very basic automatic peer/dependency finding in the said filepicker such that we p…

Maybe these posts can help: [image] Loading objects as blobs Questions You can try to override the FileTools.RequestFile function to intercept the request for the mtl file: https://playground.babylonjs.com/#WGZLGJ#2500 (see also the answer from @bghgary below mine)

Thanks, exactly what I’m looking for! For some reason I hadn’t explored that part of the docs.

Instead of passing files, I first tried using Tool.UseCustomRequestHeaders and setting the proper headers for authentication on Tool.CustomRequestHeaders, but I kept getting 401 errors which I think stem from the fact Angular is trying to handle the outgoing/incoming web requests. So, I decided to …

Can’t you use the Tools.PreprocessUrl function to turn a standard url to a blob url as described by @bghgary ? It’s hard to tell what’s the problem is given the error message without a repro.

Yeah, my bad. I understand trying to figure things out through tiny excerpts of code from a much larger project is rarely fun or possible, sorry about that. I did come across the post with the PreprocessUrl solution, but I’m not sure I grasp how that would work or how it could help me. Do you mean …

Yes, your code snippet was actually what I had in mind for the Tools.PreprocessUrl usage.

Somehow the requests are now working properly using CustomRequestHeaders, :slight_smile: only problem I’m facing now is loading the textures, just like discussed here. [image] Obj material's textures cannot be downloaded Questions Our server configurration asks for an aut…

So, here’s a follow-up: One hurdle is that our webDav endpoint isn’t configured in a way that is compatible with how the LoadImage seems to work by default (creating a new HTMLImageElement object by just setting the passed url as source, without making an actual CORS ‘GET’ request) or with “use-cre…

I can see there is a Tools.CorsBehaviour property and a Tools.SetCorsBehavior() function, maybe it can help somewhere… However, I’m not very knowledgeable about url requests / CORS problems, let’s see if others have some solutions for you.

Referencing to this: Another way of getting picture for new BABYLON.Texture(path, scene) - Questions & Answers - HTML5 Game Devs Forum I think I’ve almost got it working by overwritting the LoadImage function to force a proper xhr request: Notes: -I can’t seem to find WebRequest.onload with babylo…
