Query about EXT_lights_image_based extension

[Jarreddebeer]

Hi there,

Really enjoying your library, kudos and thank you for it.

Is there an extension floating around for EXT_lights_image_based?

I noticed the other 3 EXT extensions are implemented, and am curious if this 4th one is available. If not perhaps I can try my hand at an implementation, but I don't have an intuition for how much work is involved, would appreciate your advice.

Thanks

I don't have an implementation of EXT_lights_image_based currently. I've been delaying on that until seeing where adoption is headed. Notably, there's an alternative proposal in KhronosGroup/glTF#1956. If you wanted to try implementing one or the other, I think these two existing extensions would be good references:

Thank you, I wasn't aware of the alternate proposal.. i'm pretty new to the space. Perhaps i'll also wait and see, but will learn from your links in the mean time, appreciate it
