I tried both ways now but nothing worked.
I also followed this video tutorial The generated wrl file imported in blender gives me only 1 Planes and a Cam...
(As you can see in the Video that its also possible to use Blender)
Also the Created VRML folder remains empty, regardless how many times i try it.
(The emulator doesnt crash, i use the latest versions of the emulator and plugins and the VRML folder is on my Main Harddrive C ...)
