You can add a baldness map too to the hair system. Well if you have overlap due to clump width, then you have essentially answered your own question..reduce the clump width LOL thats the thing with this type of work, you have to just weigh out the pros and cons and figure whats best for you. Also try zbrush fibre mesh...paint, deform and decimate it......might be even better and you could palce it where you need it manually too! Jay
