There is a Forest Color map for this. Use As texture on surface mode. Documentation reference
Hey Rokas, thanks for the response. Looking at the documentation, this is exactly what I need. I don't fully understand how to implement the stripes though. Where do I need to put the ForestColor Map for this to work? Do I still need to create the Gradient Ramp within the ForestColor or should I be looking for some sort of preset?
EDIT: I've attached images of the grass in the viewport and the same grass in a render. It looks like it should work in the viewport, but the render keeps coming out without the variation.
