The above picture shows from left to right, V4 with Male morph at 1, V4 and M3 (click to see it bigger). The V4 muscle map is used on both V4s, and the M3 muscle map is used on the M3 figure.There are differences in the male and female muscle maps, and that is the fatty tissue on the breasts. You can see the diference in the breast area on the renders. If postwork is going to be used after render anyway, you could probably clone out the fatty tissue for a male. The V4 muscle maps are $20 ($14 if a Platinum Club member), and the V4 base figure can be downloaded for free and comes with the male morph. There is no M4 muscle map at the moment. If you choice of figures is not set in stone yet and you want to save some money getting into the DAZ series of figures, this book is a bargain!
