I will try your textures also.
I've gone through all nobiax/yughues terrain textures (they are awesome, have normalmap,specular and there is a lot of them) and I think this should suffice to replace all old ones.
I'll probably do some recoloring to fit them and the current scenery colors on terrain. Will see.
It would be IMO really a lot better to have diffuse rgb, normal rgb textures and then 3rd texture with e.g. specular power as r and height as g. Or maybe even both separate?
All saved as jpg (quality >90% or even >95%, don't want to see jpg's crap).
Much easier to change and adjust anything with terrain textures, and also would make them smaller, not png.
Ofc, I want to leave terrain implementation as it is, and just try making it in code, create a rgba texture as usual load rgb, then add the alpha to it, from the 3rd texture channel.
Wish me luck
