Texture is "inverted"

RobertJoseph picture RobertJoseph · Jan 29, 2013 · Viewed 9.5k times · Source

I just started using Blender yesterday so please go easy. I'm using Blender 2.64a on OS X.

I created this scene: a single plane and a playing card (a flattened cube).

The top and bottom faces of cube each have their own material and texture (the card face images). In the example render I simply duplicated a card and then rotated it so that I could see its "back".

The back texture is inverted while the front face is correct. I'm obviously doing something wrong.

I haven't changed any other settings.

Thank you in advance, CS

Probably the normals are wrong. To check this go in edit mode and enable Normals: / Face. Select all faces or vertices and recalculate them. If there are still normals ponting in the wrong direction you need to flip them manually.

Have a look at the 2nd part of blender export / one sided polygons to get more details and screenshots.
