I am considering getting mega fiers, but I have to know if it is possible to deform multiple objets within one ffd2x2? like putting several objets into a room, and then using a deformer on the whole room with its content.
in all the videos it looks like the scripts just work on a single mesh.
Most of the modifiers come with space warp versions where you can set up an area of space and any objects that gets near or enters that object is deformed accordingly, so they work for any number of objects, I dont think though that there is FFD warp at this time, could maybe contact the author and see if it is possible to add a warp ffd.
