This is a simple bodysuit without a zipper or other details. It might be used as the base for a wetsuit or space skinsuit. It is based on the tights helper. Noting the number of views of the original post, http://www.makehumancommunity.org/forum/viewtopic.php?f=4&t=13634#p35548 , decided to add the basic file here. That post also includes links to a zip which includes 10 textures. To deal with skin poke through see http://www.makehumancommunity.org/forum/viewtopic.php?f=4&t=13629#p35526 for details. Place all files in sub-folder named male_skinsuit_01. This would match the layout of the zip file. The UV map is included to help create your own custom suit, it is under: Optional displacement texture. See Materials for example of customized texture.
