If this were a single pass rendering, it might be very difficult to isolate the hot spots. The glow effect is triggered by any pixels above a certain brightness threshold. If we apply glow to a single pass render, we would probably get glow all over the place, in locations that we don't want. Because we've had the foresight to render separate passes for the various lighting and shading components, we can easily apply the glow effect to only the appropriate layers. Those layers would be the direct and rim lighting for the specular and coat components. Let's scroll down in the composition timeline,…
