@skavan said: don't understand the benefit of converting it to a Catmull Spline - perhaps Dave R can explain...and when I did it, I noticed some funny loops, so I performed this procedure without that step. The Catmull spline created a smoother curve. In your example you have straight runs of tiles along the longer straight segments and then a more severe angle when the next segment comes along. With the smoother curve I created, more tiles get tapered but that'll likely be more realistic. As long as you are satisfied with what you've got, that's fine. As for the "funny loops", I'm not sure what that's about. I didn't see any when I did it.

those don't sound like issues that were in the latest service release. The V-Ray material information is stored in the material's attribute dictionary in xml format. Multi-Materials have the child material xml included with them.

There are a few things that I had to deal with. I found it easier to put the dynamic attributes in a nested group as opposed to the outside group. This way you can rotate the entire door and jamb to fit it into the door opening and you don't have to keep changing the dynamic rotz. These doors can be copied, flipped and or rotated while preserving the desired angles of rotation. 4 doors.skp [image: COJv_4doors.PNG]

Awesome -- Zorro (now that I understand how to use it!) did the trick. TIG's method is a bit more elegant - but a lot more work!

just chucking in that this helped me with something I was stuck with too so Cheers

Well, I did indeed play around quite a lot to see what's happening when I am doing this. My approach was to reload the image and then go to top view and toggle undo/redo to see the difference between the B&W and the colour version. To be honest, I didn1t see any difference so I basically trust the method - true that when I go quite close in my area, the imagery is not the best as well as in those rare cases when I use this technique (to paint some small scale, artificial terrain for GE), any subtle difference would be rather unnoticeable.
