I tried out the example with AreaClodMesh and i like how its used though i don't really like the 30 seconds delay till it show :) But my real problem is that when two transparent parts of my model overlap will this area show flickering triangles with incorrect lightning or something. I guess thats a limitation or bug. Please correct me if i'm wrong :)
Anyway i still can't believe how much easier everything is with jME. Thank you guys!
