Thanks for the tip. Yes the directivity with spiral2 looks much better on the
vertical parts.

I hoped that I could avoid this because I want the pigment to look like it was
carved out of one big stone block. But maybe it looks even better if the base is
different. Will work on it and post a picture.

Thanks.

I did the column mainly for testing my open source modeler Y.A.P.R.M. I did
there a whole set of columns based on the basic element you can see in the
picture. I will provide them on the Y.A.P.R.M. webpage when I have finished the
texturing.
