ZJP, cayouMontreal, Thanks for the kind words, guys! Enjoy the Unity Asset Store! ChiliJuan, Probably your problem is with your objects hierarchy. Read this important note and change objects to which HighlightableObject and occluders are applied correspondingly. Also, I should note that you can't completely cut the glow with the fish body - only limit the fin glow area with it. Look at the image from my previous post. See this purple edge where the bridge intersects with the wall? Same white glowing edge will be visible where fin intersects fish body.
