I am currently working on several enhancements: The entire engine design is
revised and very much of the core code (network layers, model rendering, ...)
is rewritten. Another big improvement is in LightMap generation code: Visible
cracks in lighting between adjacent polygons that share a common plane are much
reduced now - click

to see a picture that demonstrates the difference.
All enhancements, including many smaller ones as well as bug-fixes, will be
included with the next demo release as soon as they are finished.
