Nope. Just tested that. Still typical numbers without percentage. If adding the name scale, internally or externally and in varying combinations, were enough to make a dial start using percentage indicators I'm sure a lot of morphs named scale throughout history would start showing percentages. Morphs and scales behave differently. Never seen it.

I think scale dials are something explicitly wired into and generated by Poser and aren't open to being created on the fly.

I'm also not seeing any On or Off in relation to those visibility dials stated anywhere in the cr2...

I think maybe there's some readscript or python thing going on with Sasha that's making this opaque.

Would be interesting to find out how Karina did it...
