Hi All -
We run a relatively complex edge blending setup with 4 projectors arranged horizontally, each aligned and blended. Because we're using ultra-short-throw projectors, precise alignment is an ongoing battle for us.
We're having an ongoing issue with madmapper where the positioning of quads is occasionally shifting. From time to time, the corners of a quad will shift left or right, leading to significant alignment issues with our overlapping outputs. I've tried hard to find any reasoning to this; sometimes it seems to happen upon reboot, other times randomly in the middle of a show when transitioning cues in madmapper.
I'm looking for tips and suggestions on how to prevent this, or how to help troubleshoot this further. It's becoming a major problem; I will spend hours tweaking and testing alignment, only to have it break and behave completely different when I fire up the system the next day.
