[Bf-committers] Attempt on duplicating modifier

[Edgard Damiani]

Hi Aaron,

Thanks a lot for the info, now I can see the modifier displayed in the
Modifiers list, but still when I add the SKIN2 function inside
properties_data_modifier.py, the UI breaks down.

I implemented the mydeform example to understand what I might be doing
wrong -- the code compiles without issue and the modifier is shown in the
list, but when I add the MY_DEFORM function the UI stops working as well.

Any thoughts on it?


Best regards,
Edgard
