Thanks for the reply I want to explain a little how we do this to help understand better. So over the years we have built a workflow that is a little different. You might be able to tell from the photo but we split our buildings into smaller obj chunks that are a slightly larger than the area that each projector covers.
Each building chunk gets its own output then that gets published internally and looped to a surface that then goes out the projector. This allows us to do our blending and any minor finally adjustments or warping on the surface.
Issues
1. we have a lot of trouble being able to see the actually points on the building.
This is situationally dependent and we would love some options to select different colors for the selection point, increase and decrease the center point possibly, having a X&Y cross hair might be a good option. different tools for different parts of the building.
Often we use a drone to fly hover close to the building and get the point exactly on the portion but even then it can be difficult to see at times.
2. Often we will get the points to snap but on flatter buildings Z axis often struggles and it seems to snap correctly but flipped. This will cause us to just see black which I assume is the back of the faces. This happens a lot and often it involves us usually having to arbitrarily selecting a z point we may not have to force it to snap close then add some more points and delete that later or move it around a little till it looks right. This is something we would like to understand more.
Questions
We would also like to know if using our loop thru surface method as I described at the beginning could become a issue. Sometimes we end up with 12-16 outputs this results in a lot of internal loops. We haven't ran into many issues but in the background is there a limit to this or quality loss we may need to worry about as we move into the future with higher resolutions?
This may be a system dependent thing, we always useable silicon Mac Studio Ultra or Mac Mini Pro with the highest chips for most of our installs and will continue to use the most recent as they release. Our source files are very high resolution for example the one you see in this photo is 15600x2600 which gets split between 12x 20k epson on the building, output to 3 FX4 HDR with custom EDID names FX4A, FX4B, FX4C. This allows mad mapper to hold the output order every boot.
Any thoughts or conversations surrounding these things we would love to discuss, these are permanent outdoor installs and we are always looking to improve and update our methods. Feel free to ask any questions and we would love to have a conversation anytime.
We run Epson's entire booth at Infocom off of madmapper so if you ever make it to the conferences let us know. We would love to show you more how we are using your product.
