wire deformation , for mapping
a deformation grid with bezier curve ...
That's THE feature for mapping ! A customizable grid in the advanced output setup would be a big step for adjusting proj on building !
Yes ! Wire deformation on the main output.
Why not be on the advanced output menu with abilty to create, as needed, the grid we need from few to plenty of Horz/Vert lines ?
Anyway you can use WarpMap to do that with prepared clips or send M8 video to another computer with this soft and adjust your projection (but you'll need 2 computers, gasp)
