Check the normals.

Yeh, select ur object and enter edit mode and hit ctrl+n to flip the normals, that should fix your problem

Should we have a sticky thread saying check your normals

I think this can be done by the exporter if you use recalcNormals or calcNormals from the mesh class. This way these problems will never show up and you won't have to do this manually.

hey wedge,

i would be careful with recalculating the normals by the exporter.

i dont know about blender, but in C4D there are some cases, which are quite rare, where the normals turn out inverted after recalc.

I think, it happens mostly with concave meshes...
A check, which is able to do it right in every single case, is very hard to code, I guess... Normals should be checked by users.

Maybe a "noob reminder" option (turned on by default but easy to deactivate...), which tells you, that you didn't yet check the normals of object ABC..?
(nah... would be more annoying than helpful

)
