solved Dynamic HDR Environment Map

[Art Vandelay]

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
probe.resetRefreshCounter
to update your reflectionTexture when you need it.

Just what I needed, many thanks 

reflectionProbe did the trick!
