There are some issues I would like to see addressed as well ...

I am working on a project where I need specific looks for the clothing I am using. Some of the items that I need have been purchased from reputable vendors, others not quite as well known.

I will not say who the vendors are, and I will not say what the products are. BUT I have found the following issues in some of the products that I have purchased:

(1) UV Mapping. Some products are UV mapped VERY VERY poorly, to the point that trying to create decent new textures for the object are nearly impossible without UV mapping the object all over again.

(2) SPLIT OBJ's.  If you try to UV map the object, you discover that the raw OBJ files are split apart at the groups. Some UV mapping programs will treat the individual groups as separate objects and split them apart on the UV map when automatically unfolding them. This isn't desirable, both for UV mapping, AND for morphing the clothing or figure in a third party application. OBJ files SHOULD be welded together at the groups, it makes for better morphing and rendering in the end product.

(3) Clothing that is saved in a non-zero pose, and with Inverse Kinematics turned on. REMOVE INVERSE KINEMATICS on clothing and zero the figure.

(4)  Earlier it was said that there isn't much you can do to make a bad pose. Ah, but there is. 8-)  Be careful of body transformations, including morphs that you don't want to include, and so on and so forth.

(5)  BONE GEOMETRY ... one of the products that I purchased was probably rigged in Poser's setup room. There is hip bone geometry in one of the actual OBJ files that SHOULD NOT be in there.

If I didn't know how to correct these issues, I probably would be returning some of these products.

In short, there are a lot of things on the content creation end of things that should be revisited and documented.
