Hi @mark
Thank you for the response, I wasn't aware of the Alignment Grid feature, it will be useful for the future.
As an example I have set up a stage - with the alignment grid feature. I am using one stage and multiple grid mappers within it. Please see attached screen shot.
I would find it useful for each grid map to temporarily display it's edge via a perimeter colour just for reference - when I am a long way from the physical stage at the video control position it can be difficult to see if the physical surface is fully covered by the content, or if indeed the content has spilled off the edge of a physical surface.
Perhaps I'm using Isadora incorrectly? As I said I'll adjust my workflow accordingly.
Thanks to Mark and the Forum its guidance and advice is much appreciated.
