I'm a "Cycles" Blender User and my projects are constructed with this render engine.
Makehuman is a very important tool for creating scenes, and after a while I decided a view days before to share my creations as makehuman assets.
I hope my assets are useful for you too.
But it's not possible to share the whole item, because of cycles materials...
I have no possibility to share the item in full quality. The idea to take a screenshot of the material and post it as preview is not really senseful because of the complexity and ammount of the different materials.
Furthermore I think, it's a good idea to share a blender file for other users as advantage for us all:
I thing that sharing the (cycles) materials will increase the advantage of using makehuman items.
When the full blender file (including the body) is shared, beginners have good examples and "professionals" maybe a good base for their own creations, so the ammount of created assets maybe will increase.
So I think it will be a good Idea to add a additional optional upload field "Blender File" to give the possibility to share materials or the whole item with the community.
Maybe, there's somebody who agrees, or somebody who agrees and can implement it to the gallery.
Only an idea...
