Thanks for the reference, actually needed this today.
Subsequently I learned these don't seem to be to scale, that is if TG size/scale is in meters. I built a road scene to scale to car track widths (right down to 0.8-1inch stones) and such and the grass is super large. Like young tree trunks haha.
Also, where is grass 10 and 6B? Do I have a different pack?
