In Poser it's possible to enter a relative path for a texture, which looks like "Runtime:Textures:Mytextures:Chainmail.jpg". Poser will search for that texture in all Runtimes, since there is no information about in which Runtime the object is.

And no, it does not put strain the system. The path is there, the script just checks 2 possible positions per Runtime, and only if the file wasn't found at the first position. Done in less than a second on my system, which has about ten runtime folders.

A ship in port is safe; but that is not what ships are built for.
