Penumbra and HPL2

[Urkle]

There is a "level editor" for Penumbra, and it's "your favorite 3d model editor". All the levels in Penumbra were created in Maya I believe. You can also use Blender to work on the models.

Even with HPL2, the individual pieces that you use in the level editor were created in an external modeller first (e.g. Maya or Blender). The difference between HPL1 and HPL2 is that HPL1 uses a single model for the world instead of a intermediate file (the .map) that references smaller model files.

So, unless someone rewrites the map loader in the HPL1 engine to support an intermediate map file that references small model, the concept of the HPL2 map editor is simply not doable.
