Is there a way to connect a slice to a single mask?
Thank you.

As you can see, the flags invade all the masks, for example I want the Italian flags not to invade the Mexican flagEl Rayo wrote:Mask are a part of a slice, not the other way around.
What would you like to achieve exactly?
Thank you so much, I solved the problemJoris wrote:The idea of projection mapping in Resolume is not that you throw random content at a random shape. Resolume is designed to run professional level shows, so you require a bit more preparation.
In your example, you probably want to fit each flag to a particular part of the surface, right?
So what you do, is using *input masks* on the Input Selection tab, you mask out your rectangular flag of Mexico to look roughly like the shape of the surface you want to map it on. You do this for every flag. It doesn't have to be precise, just the rough shape is fine.
Then on the Output Transformation, you do the fine tweaking to fit your now masked flag to align exactly with the surface.
If you do it right, you don't even need output masks at all.
If this all sounds like a lot of work, maybe take a look at Heavy-M or Madmapper. They tend to be a bit more forgiving for these type of 'let's-throw-something-at-a-wall-and-see-what-sticks' type of setups.
