I know getting started it hard so i was able to pull together some basic shaders. There not as good as the paid ones but there free. I Haven't seen a good-looking grass shader on agk yet so i worked on making one.
Feel free to use improve and or redistribute at will. Drop me a link if you use it in a game so i can check it out, please. Grass doesn't support lighting atm
The grass sways in multiple directions. adjustable
Realistic color variation.
Fades in at range as chunks render and auto deletes as player moves.
Works with Vulcan only currently. If you are using planes, it has basic billboarding capability built in.
splat map
Splat map supports light ambient light fog haven't figured out the shading yet.
I recommend using objects rather than planes since you can get much better performance from them.
origin of grass objects should be set to individual objects and not the group or it will cause sliding.
the grass is automatically mapped to the terrain using a splat map and a heightmap for areas where grass i mapped and at the correct height.
