Yesterday, I downloaded what I had assumed was the latest version from the DAZ site. in just checking, my copy says that it is 1.2. However, it does not "automatically" read the mtl files: nimrod89 is generally correct. But not quite - that is a person will not have to "assign" the files in the sense of "mapping" a texture file exactly to the UV coordinates of a model. (Thankfully!) Now that I've explored it further, the files do have to be slected by hand using the Color (Pick a File) Portion of the Surfaces Tab. (Hmmm, not where I would have located such a basic operation....) DS "reads" the texture mapping info in the *.obj MTL file fairly accurately, it seems. It knows when there is more than one texture map applied to an object, and it seems to accurately read the UV mapping coordinates for each of those texture files. However, since you must select them manually, a drawback to this program is that there is no clue as to which of several texture files might be the _material1 and the _material2 and so forth. So a user has to guess, or in the case of a person who purchased some models from me, I am going to have to construct a list for him for each of mult-texture file 56 models. Ugh! BTW, I found the Manual ("Artist Guide") to be well-written on this subject. (With the slight failure to note the above problem.) In generally, it provides excellent plain-language explanations and illustrations for the subject of handling material and shader settings for any 3D program. The toolset for managing and applying these settings also appears to be well-done in DS. My thanks to nimrod89 and to Barrett James for helping me work this all out.
