When using tagtool for projection mapping on buildings (or other objects), it would be a very usefull feature to be able to have a blueprint drawing as a locked background image.
For now I can import an image and use it as a layer. But certainly when having workshops with multiplayer, people tend to move this layer accidentially. And re-alligning it perfectly isn’t always easy.
So being able to lock layers or setting an imported image as background would be a great feature. Or is this already possible?
