I convert an existing 3D model in FBX format to glb format through blender, and then load the converted glb format model into hubs as a scene through Import From Blender. When I use this scene, the scene is All black.

@LangDaoAI @ChuangqHu Double check you have at least one dynamic light or an environment map for lighting. We should expect the scene to be completely black if we have no lights or image-based lighting from the environment map. Use the 'import from blender' option as you did before. 👍

A few helpful tutorials to check out:

@matthewbcool thanks quick reply and suggestions! We will check and read the two tutorials carefully and will feedback you later.

no problem! Hope that helps. If you are going to add a dynamic light, keep in mind lights have a pretty big impact on performance and you will want to remember to use the Hubs component and export 'punctual lights' in blender.

Adding an Env map gives you quick image based-lighting:

I've got it ，thanks

[matthewbcool]

aweseome! just in case others stumble on this thread, the answer was likely you need to add a light component with the Hubs exporter to the sun. Was that it?

[nullgogo]

Yes, that's exactly it
