Hi all,

For an OpenGL based export I need to sometimes repeat only the u or v dimension
of a texture.

I've been searching but it seems you can only disable repeat for both u and v
combined using the "once" keyword in the concerning image_map block.

Is there any way / work around to toggle the repeat for u or v separately?

I'm using this macro as a place holder

--------
#macro getPngMapType(idx)
  //POV-Ray does not support u or v only repeat.
  // for the time being use repeat for both in all cases.
 #if (getPngNeedsURepeat(idx) | getPngNeedsVRepeat(idx))
  map_type 0
 #else
  map_type 0 once
 #end
#end
