Simon,
Thank you for the detailed instructions. Fantastic! I am heading out to the Catalyst to set that up now.
However;
The 44'6"wx6'6"h screen plays in two positions. One very near the top of the over all projected image and one near the bottom. I imagine that I will need to apply layer key-stoning to the content and a shutter layer when the screen is in the lower position.
Can I use use layer keystone with your recipe? or do I need to apply key-stoning to the mixes?
Thanks again.
Michael
