Quote - As I wrote the script being discussed, I can assure you that it doesn't need to change geometry or invalidate morph deltas or anything like that.

If you open a saved file which has been subjected to Python geometry-level manipulations, you should find that the original geometry references have been replaced with geomCustom blocks, effectively making the procedure another type of geometry-switching.  Using Python to do it may offer more flexibility for the process, but it should still be an all-or-nothing approach, unless the code is calulating blended UVs from the UVS data file, for each frame.  To get an animated blending effect this way, each frame would have to be recalculated while the animation is rendering.  Whatever UV data has been plugged into the modified geomCustom geometry will still be present globally for that geometry, with no variation by frame.  Or such is my armchair reasoning-based understanding of the matter.  :lol:  This was one of the "complicated tricks" I was referring to.  :unsure:

But if you've made a script, bravo!  Excellent news.  :woot:

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
