Try adding in bloom as well, it's probably one of the most simple post processing effects you can do and it adds quite a bit to the game. For example, here is the very first bloom shader I made:
That was more of a blur than a bloom shader. It made everything look... blurry
I considered adding such a filter for items far away, but never really got to it.
Finally, check out parallax mapping, it's another really nice effect. Simple as well.
I had a look at that today actually and while it can be a nice effect one some kind of blocks it seemed like a lot of work as I'm not that good with the picture editing programs
From your images I can't tell if you already have this, but try adding in some "froth" where water touches land, it would make it look a million times better. Unless of course if you already added it, as I said I couldn't tell.
I indeed didn't add that. Again mainly as I wouldn't know how to, but if I get some freeze and want to dive into something really difficult it is one of the effects that I'd like to add
Have you experimented with making the effect stronger?
I tried but as the normal maps aren't of that high quality it made it look quite bad. I'll revisit making the effect stronger once I have better textures.
Now you guys made me dive into SSOA again, I'll never add any new content like this
