[edit] Quirks
This format is packaged in a RCOL container, however doesn't adhere to the same standards that most do.
- Declares a null resource key(00000000:00000000:0000000000000000) making it harder for tools to generically infer what type it is.
- Contains a "Standard" TGI List, rather than using the built-in RCOL external references
- Due to using the standard list rather than the scoped RCOL list, references made in the MTNF are interpreted differently
- Pets EP introduced animal meshes that tend to have more than 1 uv-channel per mesh(uncommon or non-existent in previous human meshes)
[edit] Vertex Format
DWORD DataType DWORD SubType BYTE BytesPerElement
[edit] DataType
| 1 | Position | (3 float == 12 bytes) |
| 2 | Normal | (3 float == 12 bytes) |
| 3 | UV | (2 float == 8 bytes) |
| 4 | Bone Assignment | (4 bytes) |
| 5 | Weights | (4 float == 16 bytes) |
| 6 | Tangent Normal | (3 float == 12 bytes) |
| 7 | TagVal | (4 packed bytes) -- colour channel data |
| 10 | VertexID | (dword == 4 bytes) |
[edit] SubType
| 1 | floats |
| 2 | bytes |
| 3 | color |
| 4 | dword |
You calculate the offset of each element from the sum of the previous BytesPerElement
Based on contributions from karybdis and atavera
[edit] Vertex Data
[edit] Reading Vertex Data Blocks
For each vertex, you need to loop through the VertexFormat as defined, and read the information in order.
The order can be completely arbitary, and varied in size.
Here is some example code in c# to do so:
for (int i = 0; i < numVerts; i++)
{
for (int j = 0; j < vertexFormats.Count; j++)
{
float x = 0;
float y = 0;
float z = 0;
vertexFormat vf = (vertexFormat)vertexFormats[j];
switch (vf.dataType)
{
case 1:
x = reader.ReadSingle();
z = reader.ReadSingle();
y = reader.ReadSingle();
sb.AppendLine(" XYZ: " + x.ToString() + " " + y.ToString() + " " + z.ToString() );
break;
case 2:
x = reader.ReadSingle();
z = reader.ReadSingle();
y = reader.ReadSingle();
sb.AppendLine(" Normal: " + x.ToString() + " " + y.ToString() + " " + z.ToString() );
break;
case 3:
float u = reader.ReadSingle();
float v = reader.ReadSingle();
sb.AppendLine(" UV: " + u.ToString() + " " + v.ToString() );
break;
case 4:
sb.AppendLine(" Bone: " + reader.ReadUInt32().ToString() );
break;
case 5:
float w1 = reader.ReadSingle();
float w2 = reader.ReadSingle();
float w3 = reader.ReadSingle();
float w4 = reader.ReadSingle();
sb.AppendLine(" Weights: " + w1.ToString() + " " + w2.ToString() + " "
+ w3.ToString() + " " + w4.ToString() );
break;
case 6:
x = reader.ReadSingle();
z = reader.ReadSingle();
y = reader.ReadSingle();
sb.AppendLine(" Tangent Normal: " + x.ToString() + " " + y.ToString() + " " + z.ToString() );
break;
case 7:
// Note, not splitting this up yet just reading an int
sb.AppendLine(" TagVal: " + reader.ReadUInt32().ToString() );
break;
case 10:
sb.AppendLine(" VertexID: " + reader.ReadUInt32().ToString() );
break;
}
}
}
Note that basically we just look through the VertexFormat, and read the data in order. There is no fixed "vertex format" version, it's all controlled via the vertexformat data.
