This is the link to the tutorial I learned to do Multiple Runtimes with. One thing I have discovered while trying to help others set up external (multiple) runtimes, is that the confusion comes from people thinking that they are different. They aren't. A runtime is a runtime is a runtime no matter where it's located. They all have the same folder structure. The only difference between an external runtime from the poser 6 runtime is that the runtimes sit "externally" outside the poser 6 folder... and are added to the library inside Poser. They function in exactly the same way as your poser 6 runtime folder does. One thing with external (multiple} runtimes is that you have to **copy** the morph folders from inside the first level and inside the first level of the library folder to the same place in the main poser 6 runtime. How you choose to organize each of your runtimes is entirely up to you. I personally organize by theme (V3 character addons, V3 Clothing, Props, Angels and Faeries, Mermaids, Lighting, Plants, Animals, Aiko etc). Just make sure that when you decide on an organization method that you remember to select the proper runtime for the item you are installing (IE: V3 Clothing for any clothing items; Props for any prop type items etc).

able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
