Are you sure you are outputing a objectspace normalmap?
Try the generator class, to make your normalmap.
If it looks good, that's probably because you export your map as
tangent normalmaps.
the z information is used/applied another way, and I think that's what
is happening here.
not sure tho...
note that tangent maps will be supported soon

Hi there!
I have created simple application, which load normal map, simple
texture and shirt model, but for some reasons it looks pretty strange
- like if normal map was inverted for some reason (showing dark
instead of light and vice verse)

Location of the models the same as in the source.
Any ideas what could be the reason?
- problems in 3ds model (it was created in Maya, exported as obj,
imported into 3dmax, exported as 3ds)?
- problems in normal map?
- problems in lights settings in action script? I have played with
different settings, but was failed to locate reason.
- bug in away3d?
Right now I dont have any ideas how I can move forward with this bug,
so any help are welcome.
