I bought the Pariah Studios texture pack the other day (pariahstudios.co.uk/texpackpro) just to have on hand for upcoming projects. I was working on something the other day that I thought would be good to use the 'Lawn' texture that comes in the Hair folder. But, having never used the hair module in C4D before I didn't know how to get it working (You can't just drag and drop a hair shader onto an object like a material). After some googling and a sample project I found online, I was able to get a better understanding of how the setup works. Obviously still a lot to learn, but it's a pretty cool module to play around with.
