Great job again Reece
Going through your changes I would say that most are compatible with OLC's own tweaks, as he went mainly about fixing glitters and issues. I hope both mods good points can be combined later
Also, have you tried modifying the values used by Leovampire for his "Living breathing ocean" to see how that improves your scene.dat? In the Sh4 scene.dat that was a major breaktrough that gave new life to the ocean
