Is there a way to load an alpha mask into World Machine and run that like a mask, similar to the Layout Generator? Say I want an island in the shape of an "S", make a mask in PS and then bring it into WM, use that set the limits on an effect.
You know what, I figured out it. Hate when that happens, you break down and ask for help and find the solution 5 minutes later. I Googled like crazy too but there are so many hits on world machine + mask. The last generator on the right is a file input generator.
