Thanks.  This is very helpful.

Quote - After importing the obj and setting the material in the material room (image node pointing to your texture image) you go to the props library and click the + at the bottom , follow the prompts and it saves it all as a prop pp2 file.  Just zip the pp2 file and its thumbnail png, and the texture file in the textures folder. 

Right but I don't want mix up the files I want to put on a CD with my computer files (Folder "Smith Micro")  So If I create a seperate folder with "Runtime". "Textures" "Geometries" etc. then it should work the same. Right?
