Ahoy,
Are these guys represented in VOPs in some non-obvious way or missing for now?

There are many, many missing VOPs right now sadly… I suspect these are among the missing.

Ah shucks… that's about what I figured. Thanks.

Not sure if you are aware, but you could easily create your own VOPS for those functions. I learned how to do that here:

I also threw together a quick example for the phonglobe function. I hope it helps!

Hay, thank you so much Dan for that example and for reminding me about the old school blog.

Hey Dan ,
I am no expert at making my own vops . Would building a fit01 vop be a relatively simple learning type exercise .

fit01 is not a VEX function, it's expression. You use expressions in nodes slots (like in transform or scale slot) not in Vex.

I can see fit listed as a vex function. I automatically presumed you could take fit01 and turn it into a VOP. If this is not the case what's the equivalent in vops ?

fit is indeed a VEX function, however fit01 is not. The VOP equivalent of course is the Fit Range VOP. You can have it fit any range you'd like. Between 0 and 1, 1 and 0, -1 and 1 or any other range you'd need.
