您需要重新应用Input Color Space Rules。

import maya.cmds as cmds
import pymel.core as pm

shader = cmds.shadingNode( 'anisotropic', asShader=True )
file_node = cmds.shadingNode( 'file', asTexture=True, name="dispMap" )
# file = ( '/Users/me/Desktop/texture.jpg' )

shading_group = cmds.sets( renderable=True, noSurfaceShader=True, empty=True )
cmds.connectAttr( '%s.outColor' %shader , '%s.surfaceShader' %shading_group )
cmds.connectAttr( '%s.outColor' %file_node, '%s.color' %shader )

cmds.polySphere( n='mySphere', radius=5, sx=40, sy=30 )
cmds.select( 'mySphere', visible=True )
cmds.hyperShade( assign=shader )

colMgmtGlob = pm.PyNode( 'defaultColorMgtGlobals' )

for f in pm.ls( type='file' ):
    colMgmtGlob.cmEnabled >> f.colorManagementEnabled
    colMgmtGlob.configFileEnabled >> f.colorManagementConfigFileEnabled
    colMgmtGlob.configFilePath >> f.colorManagementConfigFilePath
    colMgmtGlob.workingSpaceName >> f.workingSpace

完美，它的工作，因为它应该设置后，文件格式为“原始”在我的情况下，感谢安迪。
