i am working on the procedural cities tutorial in H9 and have run into a snag. the issue is in regards to assigning shaders randomly by modifying the "vm_surface" parameter in the geometry spreadsheet. in H8 there was a "vm_surface" parameter that listed out all the details of the shader. in H9 this field is called "shop_vm_surface" and only lists the path to the assigned shader. i am assuming that i need to do something different to see the shader definition string so i can modify it. any assistance would be greatly appreciated !
