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.
