When selecting gltf format, the model appears black, the model can not get out
the reason:
Our design department is probably to do with 3dmax or maya; when exporting the model, no gltf format; if 3dmax or maya obj export and then import into the blender, then export gltf format, they are easy to re-format data is lost during the conversion process appear. (This time you will find your model out of the show is black, in your code that there is no problem, you will find that the background is not being given, other models can also show up)
Solution:
We design department model made out of lead out into this website format conversion www.sketchfab.com model website (gltf, fbx); https://sketchfab.com/3d-models?date=week&features=downloadable&sort_by=- likeCount; while the Department of design also need to engage in the design, further fine-tuning on the site; displayed on this site is performing, is after exporting, we can webgl here to show normal results.
If the code is not the problem, then try to zoom it; I have experienced in doing the project, magnified 10,000 times to the model, a model that was out Diudiu.
