Any of you that have clicked the tags on the new libHSPlasma page will have found this by now, so I figure I may as well come out with it. I was originally going to wait until I could show screenshots from inside Uru of the first age exported, but it seems kind of silly at this point XD.
AgeCreator is a new tool for creating Uru ages. It's not tied to any specific modeling program, and is in extremely early stages of development. The big design goal is to abstract Plasma objects away whenever possible, through GUIs and grouping sets of related Plasma objects into a single meta-object that the user sees. It's really too early in development to give much more detail - I just haven't decided on a lot of things yet.
It stores all the data in HSPlasma objects internally, so the "export" process is very simple. This makes the internal object model (mapping HSPlasma objects to the "objects" the user sees) somewhat complex. The really big advantage of this in my mind is that you can import an age, add an object, and export the age without losing any existing information.
A unified GUI application that works directly with Plasma files also allows teams using multiple modeling programs to work on the same project with relative ease, and allows someone whose preferred modeling program isn't support by a direct PRP plugin to work on URU ages.
At this point, it can load simple OBJ files and export mesh data with mesh colliders. Lots of the GUI features aren't implemented yet (notably load, save, and object deletion).
It's easiest if you've installed libHSPlasma using my CMake scripts (it can use the CMake config file that's installed as part of that process), but it's possible to point it to any built libHSPlasma. BUILD.txt has instructions. Icons only work on Qt 4.6, but the code should now build with Qt 4.5. I've built it on 64-bit Linux with GCC, and 32-bit windows with MinGW.
EDIT: latest download link is at the top of this post now.
EDIT: adjust some statements to match the current state of things.
