Yes I know reflections are hardcoded, sorry I just listed the main things I see as sifferences and wanted to say that if one of them (post process) can be implemented in SH3 that would already improve a lot the looks of the game
Do you have SH4? The post process filters there are apparently simple, but do a lot to improve image eye-candy. Contrast is higher, colours are somehow deeper and livelier...I really like it a lot and would love to see it in SH3
