Does anyone have a step by step explanation of how to use grass/grass clumps? I've repeatedly searched the forums and have found any number of people struggling with this, but I have yet to find a definitive explanation on how to implement this that actually seems to work.
I've set the group bounding box about the region I want to populate, given the default shader a color (red! you'd think that would show up against a green surface shader...), enabled both the individual clump and the population, checked 'sit on terrain', etc, played with number of blades, blade length, clump size, and absolutely nothing shows up.
