Title: UV coordinates
Post by: Melssj5 on February 04, 2006, 02:52:04 am

Hi, how can I change the uv coordinates of a md2 file, I mean changing the file propierties to change the information of the fil about the uv coordinates, I have a md2 file that appears with the textures placed inverted, up to down.

Why not just flip the texture?

because I must redistribute that model, its an animation of a paper moving, but the qtip exporter make it appear with wrong UV coordinates.

The animation will be used in a comercial software called concayo viewer, used to watch digital magazines, very similar to zinio. They use another engine to do the render because its in vb.net. But I want to change the uv coordinates of my animation.

So you want to modify the file itself, not the coordinates after loading...? In that case, i have no clue. Maybe using another exporter will help... :?:

Well, how do you know how to set the texture in this kind of files?

Well, JPCT can load md2 files, so I want to know, wich bytes  do you read from the file that tell you how to set the texture on the map.

It loads MD2 according to the specs of the file format, which can be found here for example: http://tfc.duke.free.fr/coding/md2-specs-en.html
