b3dm Runtime import

[dhulsegge]

Hi, i was wondering if it is possible to import b3dm or the GLTF inside the b3dm with the usage of GLTFast

Hi @dhulsegge ,

As of now that is not supported.

I'm no expert when it comes to b3dm, but I'm quite certain that one can write a b3dm loader that uses glTFast to load the glTF payload within b3dm (granted the content is valid glTF 2.0).

Note: b3dm is becoming obsolete, afaik.

Hi atteneder,

thanks for your quick response. I really love your library and i think its the best out there now.
i found also this: https://github.com/NASA-AMMOS/Unity3DTiles but it uses UnityGLTF...
if i check this answer the payload should be a valid GLTF

Yeah, so it might be as easy as replacing UnityGLTF with glTFast here:

https://github.com/NASA-AMMOS/Unity3DTiles/blob/master/Assets/Unity3DTiles/B3DMComponent.cs

Note: glTFast does not support colliders nor LoDs. The script above suggests UnityGLTF does.
