just tried a workaround… @blender…added sun light to the scene and few configurations, exported in gltf format seems sun light is not exported inspite of selecting “punctual lights” while exporting in gltf format… ![sunlight.PNG](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/d/6/d69ff3e771709a3beb28ada7902df4b29a8226a2.jpeg) @sebavan can u help us how to get this effect ---

This is not supported in Babylon or GLTF ☹ there are some discussions in progress for GLTF to add it but it is not there yet cc @bghgary to confirm ---

The working group merged the IES extension already. It is here: [glTF/extensions/2.0/Vendor/EXT\_lights\_ies/README.md at main · KhronosGroup/glTF (github.com)](https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_lights_ies/README.md). This is a multi-vendor extension so it does not need to be ratified. I am only aware of NVidia supporting this extension. We are free to implement it, but I don’t know how complex it is. ---

@bghgary in Babylonjs 7.0 any update in the IES lights, i could not find anything on this This [gltf](https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_lights_ies/README.md) approach is too complex to implement. Any help with relavant PG would be great Thanks vij ---

No, we haven’t made any progress on this. Why do you say the glTF approach is too complex? ---

Does Blender support exporting to glTF with the IES extension? ---

My guess is that Blender doesn’t support the IES extension since it’s relatively new. Without that, the pipeline will be missing a step. I also noticed there is another thread on this topic: [IES light profile support - Feature requests - Babylon.js (babylonjs.com)](https://forum.babylonjs.com/t/ies-light-profile-support/36088) ---

Ok team we have an implementation being almost done and I would like to also support the gltf extension Is there any gltf file that I can use. I do not think blender supports the extension based on my tests
