The Creator will have to invest on the models just to start off working. there might be an issue considering that LH is already a morph. Polygons might already reached some limits on certain areas. Building morphs upon a Morph might be difficult if the Polygons shape has already changed. On the sample of V4 male Morph you can see that the limits are reached on the Nipple area. On V4 the only solution was to have good muscle morphs based on V4 base shape, these could be applied in combination to the male morph with good results. It would mean that the muscle morphs have to be built on LF and these have to work in combination with LH. Is there any Smoothed Line render of LH around to see how the Polygons are built ?
