Can anyone point me in the right direction for info on defining a material that I can call up using the 'ind' thingy, but is actually a parametric material selection? Or is that tail chasing?
I need to define material MYCOLOUR which would be called from the parameters selection OR be able to remove the ind(material.. from groups and replace it without causing it to nuke the last 3 lines of coordinates.
I do not fully understand what you are trying to do but from what I understand I believe this cannot be done with GDL.
If you explain it further (maybe with illustrations) then I might say with some more conviction that it is not possible.

I had made a collection of bits that were created and given an indexed material value that I wanted to control parametrically, basically as per the post from Wrathchild the entire ind(material...) chains could be replaced by the parameter name - the point I missed when first trying this was the need to get all of them for each element.
