Vertex Map


Per point data (vertex maps) defined by an object can be accessed via the Cinema 4D Vertex Map shader. You must add a Vertex Map shader to the network and drag & drop the selected Vertex Map from the object to the Vertex Map parameter.

Vertex maps are exported as user parameters with a vmap_ prefix and lower case. For example, the vertex map named My Vertex Map is exported to vmap_my_vertex_map. You can also use the user_data shaders to read these values.


By default, all vertex maps of an object are exported to Arnold. To specify only a subset of the vertex maps or completely disable vertex map export, you have to add an Arnold tag to the object and change settings on the Export tab.
