I'm attempting to render a very old scene I created in POV-Ray v3.1 with
  

POV-Ray 3.6 and am getting an error on a lathe object where I've used a 
 

vector instead of a UV_Vector.  Unfortunately the value for the vector i
s  

generated by vrotate() like so...

#declare brace1_1 = vrotate(<curve+ringThickness, 0, 0>, maxAngle*z) -
  

<curve-barrelRadius, 0, 0>

How do I convert brace1_1 to a uv_vector so x=u and y=v?

i'm an idiot.  Ignore this post.  I'll repost it in the povray.general  
newsroom.  Sorry.

My name is also Charles Worm. Very interesting to know that there is
