python 在当前帧设置一个键并删除所选控件/对象上的所有其他键

Posted 2021-05-09

import pymel.core as pm

current_frame = pm.getCurrentTime()
curves = pm.findKeyframe(curve=True)

first_key = 0.0
last_key = 0.0

for curve in curves:
    key = pm.findKeyframe(curve, which='first')
    if key < first_key:
        first_key = key
    key = pm.findKeyframe(curve, which='last')
    if key > last_key:
        last_key = key

pm.setKeyframe(insert=True)
pm.cutKey(clear=True, time=(first_key, current_frame-1))
pm.cutKey(clear=True, time=(current_frame+1, last_key))
