Smoothing problem on LowPoly Track

[guma]

Hi,
I try to make my first STK track in blender 3.6. Its a lowpoly track. However when i run the track in STK everything gets smoothed and the track looses its "edgy" style. Is there a setting I missed ("Smooth Normals" is disabled)? Or is this smoothing done by STK?
Currently texturing is done with 40x40 images of just one color (so there's an image with "green", one with "brown" a.s.o)

Thanks for any help.

Cheers
Martin
