Dynamic HDR Environment Map

Art Vandelay

Recommended Posts

Hi all,

I have a 3d room I created that changes once in a while. I would like to create an HDR environment map of the room automatically so that PBR materials reflect the actual room. It doesn't need to be in real time, I can update it every couple minutes for example. Is there any way to do this?

Thanks! :)

Hi Art Vandelay!

You can of course update the property reflectionTexture of the materials you need to update (skybox's material included). 

This will work if your 3D room changes from a static state to an other static state and you have the textureMap.

However, if your room is fully dynamic, you might find a way to do what you need using reflectionProbe as reflectionTexture.

Because probes are heavy, I suggest you to use 
probe.refreshRate = BABYLON.RenderTargetTexture.REFRESHRATE_RENDER_ONCE;
to avoid computing the reflection each frame.
Then you could use
to update your reflectionTexture when you need it.
