Topics I've Started

Custom file format ripped from a .3DS. Trouble displaying object and texture mapping.

11 July 2012 - 05:11 PM

Basically, my problem is this:
I've created one program that rips out only the relevent info from a .3ds file and stores them in a new condensed format.
My DX program then loads the info into vectors and buffers them.

Now I had this working before I tried to use U,V data, and it displayed the object fine. But my object has two texture maps. Its basically a sphere, half with a planar map for one texture and the other half with another planar map for the other texture.

Now when it try and display it, the object is messed. A jumble of polys, and the texture is highly tiled.

I'm looking for advice, not only on how to solve my problem, but also any tips in general for the program.
I'm intermediate with cpp, so please bear with me.

First the 3DS Converter.

Now, when I try to render the object with just one texture, it looks like the following. Incidentally, if I don't set a texture and just try to render a simple diffuse object, the object shape is the same.

When I try to load only the faces the related to each texture, I don't even get that, it flickers between two indistinct shapes:

and just so you know what the object is meant to look like:

And incase you need it, the .sd1 file.

So, where am I going wrong here? I've stepped through and I can't see any faulty data. Everything seems as if I should work, but clearly, no.
Any help would be greatfully recieved.
