Traps'n'Needles

I was bored...

WMOs...

Today I tested my multi-group exporter and had to realize that there is something in the files I don't really understand :/
I mean I could walk on the wmo but I couldn't see it - wtf?
Ok I have now the best wmo-tool as far as I see(doodadadding,materials,textures etc.) but it makes me sick that there is something which doesn't work properly *nrg*
