I have a grid in a composite which is actually a PNG. I set up a grade layer to highlight squares on the grid and then realised that the grid is too large. When I make resize the grid, the positions of the highlights (determined by masked on the grade layer) do not stay in their appropriate relative positions. Can I fix this (without making another composite; that's not practical because then I'd need to set up synchronised animations in to separate composites).
Thanks for help.
