Inverse Z-Coords in OBJ File ?

[endemoniada]

Hi guys,

When I export as .OBJ the z-values are inversed (0.5 becomes -0.5 and vice-versa.)

Am I doing something wrong or is that normal ?

Thank you.

i think it really depends on what application is importing the OBJ file. the world space of 3d apps are not always the same.

LWO files (at least in my loader) always come out with the same Z signedness as they are in LW. Now if you're going between different handedness (like going to an OpenGL mesh), Z will have to be negated.
