在Blender中处理镜像角色时,有时会遇到动画不能正确运行的问题。一个可能的原因是在运行动画时,角色的骨架和动画并没有彼此镜像,因此需要调整镜像骨架和动画的关系。
下面是实现以上解决方法的Python代码示例:
import bpy
# 获取角色对象
char_obj = bpy.data.objects['Character']
# 对角色的各个部分进行镜像操作
for bone in char_obj.pose.bones:
mirror_bone = char_obj.pose.bones.get(bone.name + '.L')
if mirror_bone:
mirror_bone.matrix_basis = bone.matrix_basis.copy()
mirror_bone.matrix_basis[0][0] *= -1.0
# 将动画关键帧应用到被镜像的骨架上
for action in bpy.data.actions:
if action.users > 0:
for fcurve in action.fcurves:
if fcurve.data_path.startswith('pose.bones['):
if '.L' in fcurve.data_path:
new_data_path = fcurve.data_path.replace('.L', '.R')
mirror_fcurve = action.fcurves.get(new_data_path)
if not mirror_fcurve:
mirror_fcurve = action.fcurves.new(new_data_path)
mirror_fcurve.keyframe_points.add(len(fcurve.keyframe_points))
for keyframe in fcurve.keyframe_points:
mirror_keyframe = mirror_fcurve.keyframe_points[keyframe.co.x]
mirror_keyframe.co = keyframe.co
mirror_keyframe.handle_left = keyframe.handle_left
mirror_keyframe.handle_right = keyframe.handle_right
mirror_keyframe.interpolation = keyframe.interpolation
for keyframe in fcurve.keyframe_points:
mirror_keyframe = mirror_fcurve.keyframe_points[keyframe.co.x]
mirror_keyframe.co = (keyframe.co.x, keyframe.co.y)
mirror_keyframe.handle_left = (keyframe.handle_left[0] * -1.0, keyframe.handle_left[1])
mirror_keyframe.handle_right = (keyframe.handle_right[0] * -1.0, keyframe.handle_right[1])
mirror_keyframe.interpolation = keyframe.interpolation
