It looks like it’s tricky to use a combination of materials with shaders and those without. To set the right lighting on materials with shaders we needed to switch on lighting in shaders. The light there is like a yellow color or something. Looks fine in debug modus, but when we lunched the game in release modus the water become… green. Well yellow + blue is green. But we didn’t have shaders enabled on water and didn’t realise it’ll work like that after all. So now we need to use shaders everywhere… oh, crap!
