Hi @DarraghBurke @sebavan ,
happy new Year!
I have tried two models: https://playground.babylonjs.com/#8LFTCH#990
light works with one GalleryGLB-11.glb.
With others gallery_b4.glb it doesn’t work: I change light.intensity and it does nothing.
it is probably due to lightmaps textures.
Can lighting also be changed there?
