Went back and looked over the newer azone source (thought I had the latest), my apologies. This is how the fragment is handled.

Just the beginning:

FRAG_CONSTRUCTOR(Data30) {
  struct_Data30 *data;
  uint32 ref;
  Texture *tex;

  data = (struct_Data30 *) buf;

  buf += sizeof(struct_Data30);

  if(!data->flags)
    buf += 8;

  ref = uint32(buf);

Looks like a struct is made and the data is copied into it. Then we move past the size of the struct.

struct struct_Data30 {
  uint32 flags, params1, params2;
  float params3[2];
} typedef struct_Data30;

Then it looks like if the flags are 0, which I think means the texture is completely transparent, we move past the datapair which appears to be 8 bytes and then we can read in the reference.

I will try this tomorrow. I am also working on an updated version of the WLD documentation which I will release with the source of the client.
