IBL has much more “texture” to it, since it’s a capture of real light…(an image) instead of mathematical single color point or directional or spot… (including a wide intensity range with HDR environment maps), and the coloring varies across th…

all good advice! thank you the challenge for me is figuring out if I’m getting a ‘double’ lighting effect by having my lights in the render of the env map (every 30 frames), and also keeping the lights in the main render of the scene. If I remove the lights from the second render call, I’d lose ca…

Latest versions of three js use physical based lighting methods to replicate real world properties of lighting, using such a renderer effectively opens the developer up to creatively understanding, using and applying the laws of real world optics (as best currently can be matched digitally in a rend…
