Hi!
We’re building prototypes for two online viewing services that need real-time or near real-time delivery (5000-7000ms in one use case and 30000ms).
What concerns us is if it’s possible to feed the models in the scene with a continuous stream of *.FBX data which we’re rigging real-time to one or more models found in the scene.
If you’re a 3D generalist with Unity/UE4/WebGL and coding chops (I assume some torturing of JS to pull this one off), come talk to us.
Stay safe everybody!
Hey! Are you building realtime holographic / animated scan viewer or smth similar (HCAP, etc.)?
The engine itself doesn’t support .FBX import (it’s locked for in-editor use only via FBX -> JSON converter), but it’s possible to convert incoming FBX to GLTF via ThreeJS lib, and then import GLTF into PlayCanvas engine as a valid model asset. Or write custom FBX importer for your purposes, if that’s an option.
But that is for overriding the entire asset. If you want to provide a stream of FBX data that should be converted to some new vertices / triangles added to existing mesh - then it will require a significant custom effort I suppose. If it’s just stream of new animation data - using FBX -> GLTF pipeline should work.
Cheers!
Yeah, I’d recommend an FBX2glTF tool like this one. FBX isn’t a transmission format - its bloated and difficult to parse. Unlike glTF, which is fast to transmit and easy+fast to parse. And PlayCanvas has excellent 1st-class support for loading glTF scenes.
Hello,

I’d Glad to assist you.

Hello Will,
Thanks for the suggestion. Now I actually see we need to look at the fundamentals of our current stack - the FBX is clearly both on its way out and not suitable for streaming.
Hey!
Thanks for the reply. We don’t start in the XR domain, but of course, we build with it in mind - it’s just more further ahead on the roadmap. I’m acquainted at a glance with gLTF via my other work that is located in XR space and the Khronos group spec, but nothing more besides that.
I don’t believe we need further FBX manipulation, we just need a way how to feed the pipeline continuously the incoming data at runtime.
The offer is still on if you’re interested, shoot me a DM with your details and we’ll talk more.
