Data that needs clarification

Faces

s32 facetype; // 0 = flat, 1 = text, 2 = Double-Side

u32 rgb[IOPOLYVERT_FTL];

u16 vid[IOPOLYVERT_FTL];

s16 texid;

f32 u[IOPOLYVERT_FTL];

f32 v[IOPOLYVERT_FTL];

s16 ou[IOPOLYVERT_FTL];

s16 ov[IOPOLYVERT_FTL];

f32 transval;

SavedVec3 norm;

SavedVec3 nrmls[IOPOLYVERT_FTL];

f32 temp;

• How is the rendering of the different face types handled?
• Is RGB actually used?
• What are ou and ov? Offsets?
• What's transval?
• Is temp garbage?

Vertices

SavedVec3 pos;

f32 rhw;

u32 color;

u32 specular;

f32 tu;

f32 tv;

SavedVec3 v;

SavedVec3 norm;

• What's rhw?
• Is color actually used?
• Is specular actually used?
• Faces already set UV data. Why tu and tv?
• Faces already set corner normals. Why norm?

Groups

char name[256];

s32 origin;

s32 nb_index;

s32 indexes;

f32 siz;

• What's the purpose of origin? Is it the position of the deforming joint? Then where's the rest of the joint data?
• What's siz?

Actions

char name[256];

s32 idx; // index vertex;

s32 action;

s32 sfx;

• What's action?
• What's sfx?
