   I have square 128 x 128 textures (coming from a .tga file) with various elements making up a spaceship's skin. I can see the correctly textured ship in Maya and 3DS Max but when I load into Cocos3D the texture file is upside down on the ship. This is not a big problem as I can flip the image and re-save the file but with a couple of hundred to do I wondered if there was a code based solution. I read the forum and saw posts about non-square textures but not any issues with square.

   nb: The texture files are .tga because they come from old models I created on a PC years ago. I'm trying to save time by re-using lots of meshes. Some are too low poly to fit today's standards but most will work fine on iPhone.

   If you don't find a code solution (I don't have an answer to that either) you can use simple CLI tool (convert -flip) to do upside-down mirroring on all your existing files (e.g. via shell (might not be totally correct, from my head):"for i in ls "*.tga"`;do convert $i $i -flip;done").

   @sundialsoftware The command you are looking for is 'alignInvertedTextures'. Use as such:

   [spaceship alignInvertedTextures];

   Many thanks for the suggestions. I will try both approaches. I thought I had seen some texture command in a bit of source but I could not find it. I'm just happy that .tga is still a supported format. It was the done thing 8 years ago when I first did a 3D game but png seems to be king now.
