Mornin' Kaom, Get some sleep man! Here's whats going on in the above image. (Correct me if I'm wrong) It's how I reproduced your anomaly though. 1. You've inserted a cube primitive and then made it thinner by scaling it in one direction. The scaling also compresses the shader components including the Groove shader. It bunches up and looks horrible. or 2. You've created a spline object cube and then shortened the extrusion path. It compresses the mapping pattern just like scaling the cube. Don't do that. ;-) The very top image in this thread (the original one) uses a simple cube primitive that has been scaled a little but not as drastically as yours. The brick pattern and Groove pattern was tiled 4 times on my cube to get the results you see there. Another way to handle it is to use two planes with AG and MBG applied and build your own corner out of them. Unless I need to show the texture wrapping around a shape, I don't and use simple planes instead of cubes or primitives. Mark
