I am very new to Blender. Only been using it for a couple of days.

I have a 3d model(s) in an hdri environment and would like to export the model with the hdri background so that I can view the model while moving the hdri environment in 360 degrees.

When I export it in glb/gltf format, I'm only able to view one of the models with no hdri background. When I export it in fbx format, I am able to view all my models but not with the hdri background.

Basically, what I've noticed is that when I view my exported blender file on Windows 3D Viewer, it appears like the material preview mode on the blender viewport shading. I want it to export it the way it appears on the Rendered Preview mode on the Viewport Shading.

I'd appreciate any help.

  • For what it's worth, there have been at least 2 different draft/vendor extensions to glTF proposed for embedding HDRIs. None have been accepted by Khronos or implemented in Blender, because they add a lot to the size of the file, and most assets are generally interchangeable among multiple HDRIs. So for now I think you have to handle the HDRIs separately from glTF files. – emackey Aug 22 '22 at 14:07

I don't think it will work this way. The HDRI is part of the environment setting and I don't think you can export it with the model. You need to set the HDRI in the importing program. Does the Windows 3D Viewer support HDRIs?

Blender uses build-in HDRIs for the material preview. For rendering, you need to set up the HDRI in the world settings.

Furthermore, most file export formats don't support exporting textures. However, you can re-create the material in the importing program and import the textures and the HDR image (if supported) manually. The glTF file format is an exception because it supports textures and basic material settings - but no HDRI either.

In ThreeJS for example, the HDRI can be uploaded into the Environment slot. (It must be a *.hdr file, *.exr files are not supported.) Texture images can be specified in the material settings below. If you use the glTF format the images will be imported from the *.glb file and assigned automatically.
