gltf loads large models very slowly

[foreverliu]

gltf is very slow to load large models, an 80M file takes an hour to load.Can this be solved?

glTF is only a file/data format. How long it takes to load a model is (not really, but somewhat) independent of that. More precisely: glTF is designed so that it can be "loaded" quickly. The issue is therefore most likely related to the engine/renderer that you are using.

So where and how are you "loading" the model? (And are you sure that it's not only due to a slow network connection, for example?)

Uploading test.zip… The model is gltf generated by sketchup conversion, and the loading speed is very slow. I load it locally.

I load it locally.

In three.js, in Babylon.js, or in any other viewer?

_{(Besides: I don't know which button to click for the download...)}

Please try the new Iridescence Abalone model. It is just under 10MB. You can directly view the model in SampleViewer using https://github.khronos.org/glTF-Sample-Viewer-Release/?model=https://raw.GithubUserContent.com/DRx3D/glTF-Sample-Assets/main/./Models/IridescenceAbalone/glTF-Binary/IridescenceAbalone.glb. The GLB can be downloaded for local testing using https://raw.githubusercontent.com/DRx3D/glTF-Sample-Assets/main/Models/IridescenceAbalone/glTF-Binary/IridescenceAbalone.glb. Note that this GitHub repo is development for the new Sample Model repo.

The import and load time will help us determine where the issue(s) are.
