Thank you to everyone who responded. Its the first time I have posted and I did not expect a responce.
Attached is the object I have been working on. Its a frame with an artwork that may be useful to any exhibition designers out there. The frame, glass and matt board are all textured using the Apply Texture node. I had hoped to be able to use a Texture Map node of some sort to control the texture map of the artwork in the frame. Instead the way forward seems to be to wrap the network, ungroup the each frame the network produces and adjusted the artwork texture map.
I would love any comments on improvements on the network.
Also can anyone tell me where to find the node Ordered Points. I found it in a tutorial but can't find it in the list of nodes definitions.
