Instance Panel (tvpa 8.5 and higher)

[Peter Wassink]

The FXh button doesn't seem to work any idea what to do?
i want to apply a scale on an animation that is on doubles but i only want to do it on the head frames.

Recompute doesn't work either, above a certain project dimension size i found the Recompute button quite useless.

re-scale via Transform tool or the Keyframer_FX ?
indeed, the "tv_cmd heads tv_stackapply" command seems to be buggy in tvpa V.9,
meanwhile, you can try the old george command from the Instance Panel v1.2 (FXonHeads.grg).
it's rather slow, but it should still work fine.

what size ?
