Applying Material

Using Rhino v8, Complete novice here attempting to add material to solid wall face (think Shingles and siding) and rotate/scale as needed. Do not understand Older posts with Menus from older Rhino versions, they look different than V8. I need a good starting point with follow through. Bird house example see floating roof with Shingles in correct orientation and the other roof 90deg out. I have no idea why or how to fix? Any help would be great.

Hi Fred,

Hi Brian
Thank you for the video and explanation, I zoomed in and rotated my model just a you had done and was able to reproduce your example quite well. Very very helpful, I finally get it!

However, when I zoomed out I found the shingles on the floating roof had rotated to 0 deg. when they were originally at 90. If I try to rotate that one back to 90deg then the roof you used in your example reverts back to 0 deg, Apparently they are connected somehow? Is there a way to disassociated them from each other? This may be important when I try to apply siding and attempt other materials on other parts?

I also notice the lines representing the solid used to create roof sheeting bleeds through the shingles. Is that normal?

Yes, that’s because they use the same material but one surface’s U direction may be the V direction on another and as such the material’s texture uses that axis as the starting point for any rotation set in the material. There are two solutions, you could make a duplicate of the material via the right click menu over that material thumbnail and set the rotation back to 0 for that one. Then apply whichever material works best on each object. The other solution is to perform the rotation in the UV space of the object versus the texture in the material assigned. To do it that way, select an object and open the UVeditor like this from the Properties panel…


Then select and rotate the island to change how the texture is mapped…
