World Machine - custom masks?

Leech

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.

Ya file generator, often I will kinda make the layout of my terrian in unreal, and export out a map to use in wm, with the file generator input.
