Very interesting. Was able to follow your instructions and can see how uvmapper can be very useful for many things.

I also noted that the six side texture map I created in uvmap is different than the one that the grouping tool creates. It took me a few minutes to figure out how to get all six sides to show in uvmapper, but here is what it looks like. I like this layout better as I can use any square texture and apply it to any side and it fits right. I could not get it to work quite as easily using uvmapper and had to customize the textures.

With the box I did using the grouping tool, I can convert a scene I built in Poser with various props into a simple low count prop. All I have to do is set up the camera shot I need to make the texture, render the scene, and apply it as a texture to one side of the box. I can then get rid of all the extra (weighty) props I used to build the setting, and still have a scene (via a single prop or two) I can shoot from different angles, have doors and windows that open and close, etc. (I can make doors and windows work using transmaps and parenting square props with textures to the main box as needed.) All, while keeping the polycount for the scene low since my entire town or building setting is made up of only a few poser box props - speeding up my render time, making for smaller pz3 files, and quicker animations.

In short, I think both ways of mapping have merit and are worth knowing. Thanks for your help. Always great to learn new and interesting things. :O)
