Heya
Aaa right ! Thats explains a lot !
So I can reformat them and put back together any way I want. Now that sort
of works but I hit a wall if some of the names has xx_xx_xx_xx and some are
xx_xx_xx. Then I get error....
Here is basic script
list = cmds.ls('*_set*')
for objects in list:
t = objects.split('_')
new_fn = "{0}_{1}_{2}_{3}".format(t[-0],t[-2],t[-3],t[-4])
print new_fn
and here is error
# Error: list index out of range
# Traceback (most recent call last):
# File "<maya console>", line 5, in <module>
# IndexError: list index out of range #
I guess its because names have different length...
I try using Try/except:pass but then it just loop again and add 1st part to
the end so that wont work whh...
Any hints how to just subtract/delete the last part of name?
