Animated HDRI / env maps possible?

Hello, I would like to make an animate HDRI / env map if possible?

Something like a firework display or sunset of which the movement/animated can be seen in my scene’s reflections.

I know this is possible in 3D modelling/rendering software like here Make an Animated Fire HDRI Procedurally in 6 minutes! || Blender 2.82 - YouTube, but wondered if it was possible in three js also using video textures or similar?

Thanks for any thoughts/ ideas :slight_smile:

EDIT: As an update, I have just found this which has an effect similar to what I am after but it is only on one plane, not an env map

I’m not aware that the video formats supported in browsers can hold HDR values. So I would say using a video texture is no option.

If HDR is not important, you can try to create an equirectangular video and project it onto a sphere like in three.js webgl - equirectangular video panorama.

look into this thread Live envmaps and getting realistic studio lighting almost for free

in plain threejs you need to use pmremgenerator.fromScene(…)

ps the sandbox you linked doesn’t have an envmap, these are screen space reflections which is a different effect. the background is just a plane with a videotexture.
