Hey again Neodymus,
So it appears to simply be the lighting setup of the level that the puddles look better in some setups than others. Depending on the brightness of the probe capture in the area. If you want to “fake” more reflection in the puddle you can increase the reflectivity here. Hope that helps!
Hey IceDealer, I hope you’ve been well!
I do know what is causing the problem. It’s related to the way that the material calculates depth, which works great for the flatter rivers, but not as well for the waterfall. I have some ideas for solutions but they will all make the material a lot more expensive. Unfortunately I have been pretty overloaded at work lately so I haven’t had a ton of time to pursue other possible fixes yet, but I haven’t forgotten about it. Thanks for your patience.
