Retrieves a vector4 from the given offset from the given vertex id in the vertex data of the specified mesh.
A vector4 is just four adjacent floats, so you can also call DX11 GET MESH VERTEXDATA FLOAT four times and increase the offset by 4
(since a float uses 4 bytes) for each consecutive call if you prefer that.
This function will trigger an error message if the provided vertex / offset is not valid in the vertex data of the specified mesh.
Use DX11 GET MESH VERTEXDATA VERTEX COUNT and DX11 GET MESH VERTEXDATA SEMANTIC OFFSET to ensure your values are valid.

DX11 GET MESH VERTEXDATA VECTOR4 mesh, vertex, offset, vector

mesh

Dword
The mesh from whiches vertex data the dword will be read.

vertex

Dword
The vertex to read the vector data from.

offset

Dword
The offset from the start of the vertex' data to read at. Use DX11 GET MESH VERTEXDATA SEMANTIC OFFSET to find offsets by semantics.

vector

Dword
A vector4 that will be filled with the data at the given offset of the specified vertex.

This function does not return a value.
