Thanks for your reply.
I tried the Shader Effector but from what I can work out, all I can effect is the Positions, Scale and Rotation. The effect I am after wouldn’t use these parameters I don’t think.
I’m also just using the Cell Renderer (outline & edges) rather than Sketch and Toon as the tower block is pat of a much larger scene and the Cell Renderer renders much faster than S&T.
Below is a very crude mock up of the effect I’m hoping to achieve.
Thank you again for your help.
