Neal, for a green that has chest hairs and goes kaboom on your mind, here is the exact recipe developed by our Blammocorp! Super Secret Paranormal Turf Research Test Lab - supervised as always by our excellent Dr. Pat McRotch.
Texture 1: Any old colour texture with or without mow lines. Though mow lines are generally helpful to make slopes more visible.
Texture 2: Detail map, same as posted further above in post 22
Normal 1: copy of Texture 2, reduced in size to 1024, posterised to 8 colours, 0.4 Gaussian Blur, set to normal map @ blurriness 0.5
Normal 2: Run-of-the-mill grunge normal dedicated to destroying visual repetitiveness.
Re: Green Fringes: I see very little need to use them at all - the transitions are always messy and they do look a bit dodgy and ill-placed even on the best of days. Same goes for fairway fringes. If you want to use them, never make them too dark compared to the adjoining meshes, on account of a real danger of immersion-stopping visual awfulness. Blammocorp has discontinued any R&D on fringes one and half years ago.
