Does anyone know where I can find that nebula plugin (for making nebulas/nebulae in space). Another thing, can blender plugins be written for doing such things in any other langauge? I know you can write texture/sequence plugins in C, but what about an export plugin?

if you use the search function for nebular generator you willl find it.
python is the language that is used for export scripts.
what particular export are you after?
if you want links to scripts check the wiki link in my sig.

I guess you can integrate libraries done in C and C++ into python, thats on the Python Manual… but of course the import script will be then plataform deppendant (and you will need to bundle the library when distributing it)

Okay, thanks
