A mesh producer that filters an incoming mesh with an expression.
This component can only be used in the Mesh.Producers property.
Example usage: See "BoidMesh" in Steering sample project.
An expression that is called once for every vertex in the mesh. The special read/write property "V" holds the current vertex. Modify this value to change the vertex. Example of a valid expression: "this.V.X*=2;". The read/write property "N" holds the current normal. The write-only property "C" allows writing to the current vertex color if VertexColors is on. The read/write property "TexCoord" holds the current texture coordinate.
If this property is on all normals will be automatically regenerated after a the MeshExpression is executed. Turn off this if you want to modify normals in the expression.
If this property is on then the expression can set vertex colors.
If this property is on then the expression can set texture coordinates.
