3d/Uv Mesh Vertex Blend

[Richter Belmont]

CollaTKane already export 3d mesh vertex blend (called shape key in blender)...
but do not support uv mesh blend: I never seen such thing in blender and do not know if such paremter exist for .dae file.
Hook5 won't render mesh that use uv mesh blend.

3d mesh vertex blend are blend that "reshape" the value of the mesh 3d vertex, while uv mesh blend are blend that "reshape" the value of the mesh uvmap vertex.

For using these feature, your mesh must be of "SkinPolygonGeometry" type. (or MeshGroup)
If your mesh is of "PolygonGeometry" type, you simply need to change its node type to "SkinPolygonGeometry".

Code:

//TPolygonGeometry :local_R9Crown036_MESH . {[/color]
[color=#000000]TSkinPolygonGeometry :local_R9Crown036_MESH . {[/color]
[color=#000000]// TNode.SNode SPolygonGeometry :local_SR9Crown036_MESH;[/color]
[color=#000000]TNode.SNode SSkinPolygonGeometry :local_SR9Crown036_MESH;[/color]
[color=#000000]TGeometry.Shader RenderShader :local_R9Crown036_MATERIAL;[/color]
[color=#000000]TNode.Parent TTransform :local_R9Crown036_NODE003;[/color]
[color=#000000]TNode.BoundingSphere Spheref( 0, 0, 0, 1.000000027e+016 );[/color]
[color=#000000]Object.Name "R9Crown036_mesh";[/color]
[color=#000000]};[/color]
[color=#000000]...[/color]
[color=#000000]//SPolygonGeometry :local_SR9Crown036_MESH . {[/color]
[color=#000000]SSkinPolygonGeometry :local_SR9Crown036_MESH . {[/color]
[color=#000000]SPolygonGeometry.PrimCount I32(9068);[/color]
[color=#000000]SPolygonGeometry.IndexArray Array_I32 [ ... ];[/color]
[color=#000000]SPolygonGeometry.VertexData [ ... ];[/color]
[color=#000000]SPolygonGeometry.VertexArray Array_Vector3f [ ... ];[/color]
[color=#000000]SPolygonGeometry.NormalArray Array_Vector3f [ ... ];[/color]
[color=#000000]Object.Name "SR9Crown036_mesh";[/color]
[color=#000000]};

BlendControl are node that control the "influence" of the blend.(how much effect it has)
We often link the BlendControl to the game slider.
It is possible to link the same BlendControl to multiple mesh.
Exemple:

Code:

BlendControl :local_stomachBulgeX_blendCtrl Object.Name "stomach_bulge_x";

For each of your mesh 3d vertex blend, you gonna need to link a BlendControl node to its "SSkinPolygonGeometry.BlendControl" array.

Code:

SSkinPolygonGeometry.BlendControl [ BlendControl :local_stomachBulgeX_blendCtrl ];

For each of your mesh uvmap vertex blend, you gonna need to link a BlendControl node to its "SSkinPolygonGeometry.BlendTexCoordControl" array.

Code:

SSkinPolygonGeometry.BlendTexCoordControl [ BlendControl :local_pupilLDilation_blendCtrl ];

[i]For meshgroup, it is MeshData.BlendControl and MeshData.BlendTexCoordControl[/i]

For each element in SSkinPolygonGeometry.BlendControl array, you gonna need to link a VertexDataVector3f node to the SPolygonGeometry.VertexData array.
These must have a number of vertex equal to the mesh 3d vertex.(SPolygonGeometry.VertexArray)
Their value must be relative to the mesh 3d vertex. (newValue - oldValue = relativeValue)
For exemple, if your mesh 3d vertex is (0.1, 0.7, 0.3) and want your blend to change its value to (0.4, 0.3, 0.2), you gonna write (0.3, -0.4, -0.1).
The VertexData.Usage value of the VertexDataVector3f must be equal to:
655360 + the element position in the SSkinPolygonGeometry.BlendControl array.
The "position" of first element is 0, second is 1, third is 2, etc.

Code:

VertexDataVector3f :local_stomachBulgeX_vertexData . {[/i][/color]
[color=#000000][i]VertexDataVector3f.DataArray Array_Vector3f [ ... ];[/i][/color]
[color=#000000][i]VertexData.Usage U32(655360);[/i][/color]
[i][color=#000000]};

For each element in SSkinPolygonGeometry.BlendTexCoordControl array, you gonna need to link a VertexDataVector2f node to the SPolygonGeometry.VertexData array.
These must have a number of vertex equal to the mesh uvmap vertex.
[i]Unleast your using a meshgroup, your mesh already require its number of uvmap vertex to be equal to its number of 3d vertex.[/i]
Their value must be relative to the mesh uvmap vertex. (newValue - oldValue = relativeValue)
For exemple, if your mesh uvmap vertex is (1, 0.5) and want your blend to change its value to (0.3, 1), you gonna write (-0.7, 0.5).
The VertexData.Usage value of the VertexDataVector2f must be equal to:
786432 + the element position in the SSkinPolygonGeometry.BlendTexCoordControl array.
The "position" of first element is 0, second is 1, third is 2, etc.

Code:

VertexDataVector2f :local_eyePupilLDilation_vertexData . {[/i][/color]
[color=#000000][i]VertexDataVector2f.DataArray Array_Vector2f [ ... ];[/i][/color]
[color=#000000][i]VertexData.Usage U32(786432);[/i][/color]
[i][color=#000000]};
