Is EXT_lights_image_based supported in glTF export?

Question

It doesn’t appear that environment lighting is supported glTF exports. Perhaps I’m doing it wrong?

Steps to reproduce

Create a new design in Dimension 3.3.
Add a capsule to the scene.
Apply a silver material.
Go to Scene panel > Environment > Environment Light.
Confirm there’s a light or apply a custom HDR image.
File > Export > Scene.
Select glTF.
Export.

Expected

According to the EXT_lights_image_based glTF extension spec, Adobe Dimension currently supports glTF exports with this extension.

Saw

Previewing the glTF in Babylon, I don’t see the asset rendered with the expected environment light. Inspecting the glTF JSON, I see no such extension declaration.

correctthe file type allows for lights [as does Fbx as well] but the Dev team didn't put them in as it stands your only 2 options are;save the Dn file (which is a known cause of corruption when jumping across different builds}or rebuild the lighting each time you move into a new software

I think its more a case of using the right tool

Dimension is not designed for export lights and there by the wrong tool for those workflows... you can goto the uservoice forums [where the dev team hang out] and add your vote for exportable lights
