I encounter a problem while using the Zebra analysis in Shaded mode. It is very pixelated, even with flatsurface option on. If i switch to rendered mode and put the zebra analysis it appears perfectly smooth. I tryed to tweak the mesh setting without any result…
can you post a screen shot of what you are seeing? I suspect you need to increase your render mesh, (which you indicated failed) but want to make sure there is not something weird going on 1st-
