Is it worth it? Depends on your workflow.

If the idea of setting up several files and leaving Poser to render them in batches, save them, then close itself and shut down the machine (if you tell it to) would be useful to you to render overnight or while you are at work, then definitely it is a good idea. Same if you could do with layered images with separate aspects of the renders, like a render of just shadows, or a render of just AO, or ambient colour. These are VERY useful when postworking images and allow you much finer control of what is going on. Combine with the above, and it can save you a lot of time.

Glowworm also has an option to split big renders into sort of "layers".

In all, I find it very useful, but I know that has a lot to do with the way I work.
