I've actually make seperate runtimes for every product I have.

I started WAY back in the Poser4 days. I stripped everything out of the default runtime until I had one that with nothing in it that didn't crash poser.

Then I made a copy of that and renamed it to blank.

Then I installed each product in it's own runtime and renamed them.

When I wanted a scene, I just copied all the runtimes I needed into a black one and only had to deal with what I wanted to work with.

It was awesome.

I was so happy when mutiple runtime were supported.
