To Makinmagic- hear hear to the compatibility. i myself am sort of mad at the 2.03c version becuase of that. conversely, why can't we pull UF images into apo and play with them that way? i find working with transforms to be much easier than working with numbers and functions. wouldn't that be great? also: when you import a flame into UF, why can't you add mappings and "inside/outside coloring" formulas like with any UF-only images? that's my question. i'd love to play around with some of my flames by using the "inversion" mapping, but i am restricted to making a new transform with spherical as a variation, and then turning the weight up to like, 50.
