Two uv textures on one face?

i am writing an exporter for blender.
In OpenGL it is possible to have two or more textures on on face.
You can blend them.
How can I use more than one uv texture for a face in Blender?
Is it possible? Perhaps with nodes?
Best Regards



There are two ways to get textures onto surfaces in Blender. One way is through the Material Nodes. The other way is through Texture Channels (click here).
Each channel can be mapped to a set of UV coordinates, and Blender supports multiple sets of UV coordinates for the same mesh. Each texture is applied to the material and textures lower in the list by the mix method specified in the MapTo panel.
