Can you pass a blob to Scene Viewer?

[ZackARC-solutions]

I have tried to pass a blob to the src of model-viewer to load an AR scene on my 3D designer at runtime. This works fine for iOS's quick-look, but scene viewer and webxr both crash when I try load the AR scene. Is it allowed to pass a blob to Scene Viewer? as exporting the glb and hard coding it the src does make the scene viewer work.

Pretty sure that doesn't work for Scene Viewer. Can you give some details about the WebXR crash? What do you see in the console? can you share a repro link?

I have sent you a pepro link - it is hosted in arc-solutions.co.uk/test - hit view in AR

It appears you have a huge number of draw calls, which will definitely impact performance (on top of ARCore's impact). I'd recommend you collapse the model into fewer meshes and materials.

It is strange that iOS can handle it fine. I've tried reducing the model complexity and it has improved slightly, but still is running very slowly. Do you recommend using something like SimplifyModifier? It is almost like it's still rendering the whole scene during the WebXR session. Thank you for your help.

ah, in fact it is rendering the whole scene. We turn off frustum culling (because it has some animation bugs) and since MV is nearly always viewing the entire object anyway. Are you hoping to do more of an in-world walk around kind of WebXR experience?

[ZackARC-solutions]

In my case I add a bunch of glbs to a group and pass that through to MV as a single glb through a blob. Yes, basically an in-world walk atound WebXR experience - we have created a platform to design something and see it in the real world.
