All materials from the Rhino material library will default to WCS texture mapping for any textures in the material (world coordinate system, like box mapping but based on model units). If you change the texture settings in the material to Mapping Channel 1 it’ll use whatever the object’s texture mapping settings are set to. Or you can click the text link in the object’s texture mapping settings to automatically change to mapping channel 1 for all textures when you see that message about using WCS. You’ll still need to adjust the repeat after that in the material’s textures most likely as well after that. Once the texture is using surface mapping, you can use the UVeditor command to rotate one surface’s “UV” mesh which is what controls the direction the texture flows.
Here are some other more recent videos I’ve made on texture mapping that may help…
