There is the live show, we need many mapping method for different size video and image. How can i switch the mapping method quickly?
For example,as the image shows.There are only four screens in reality. The left side is throwers mapping, the right side is direct mapping. how can i switch those at four screen?
If you are talking about switching content sources on virtual objects (video screens) at runtime, there is currently no mechanism implemented in LA3.
However you can always change source itself for thrower (canvas content thrower is pulling content from). You can use ortho layout for thrower and align it so that it covers all four screens. The end result will be the same as direct mapping. This way you wont need to change sources for each video individually.
