    Is it possible to have invisible objects, such as light reflectors, in a scene without being visible in a gltf file?

    Can you give more examples what you mean.

    Take this video as an example:

    He has set up 3 planes, one as a base for the model to sit on, one as an emission light source and another as a reflector. It would be nice if I could have these in the scene creating the lighting, but not be visible in the gltf when exported. It is possible to render in Blender without showing these objects, but I don’t know if there’s a way to do that in a gltf export. Also, I have not been able to get emission planes to work as light sources in my gltf, only actual lights. See the following example:

    Didn’t you notice that the tutorial is for Blender’s Cycles?

    Instead of those planes (emissive and reflective) use rect area lights. And work in Eevee only.

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

    To exclude plane from exporting, just put them in external collection and exclude it using this form in Verge3D settings.

    All other tricks with light source will not work in the engine because all them made using cicles.

    I did notice, but as you can probably tell, I didn’t know that cycles cannot be used for gltf. I’m a complete noob to all of this. Since the lighting technique I asked about is not possible I’ll stick to more traditional ways.

    Thanks for the tips!
