1.连接节点的方法
connectAttr
例如 连接UV和贴图

def connectUVNodeToTextureNode(UVnode,textureNode):
    mc.connectAttr(UVnode +'.outUV',textureNode + '.uvCoord',force = 1)
    mc.connectAttr(UVnode +'.outUvFilterSize',textureNode + '.uvFilterSize',force = 1)
    mc.connectAttr(UVnode +'.coverage',textureNode + '.coverage',force = 1)
    mc.connectAttr(UVnode +'.translateFrame',textureNode + '.translateFrame',force = 1)
    mc.connectAttr(UVnode +'.rotateFrame',textureNode + '.rotateFrame',force = 1)
    mc.connectAttr(UVnode +'.mirrorU',textureNode + '.mirrorU',force = 1)
    mc.connectAttr(UVnode +'.mirrorV',textureNode + '.mirrorV',force = 1)
    mc.connectAttr(UVnode +'.wrapU',textureNode + '.wrapU',force = 1)
    mc.connectAttr(UVnode +'.wrapV',textureNode + '.wrapV',force = 1)
    mc.connectAttr(UVnode +'.repeatUV',textureNode + '.repeatUV',force = 1)
    mc.connectAttr(UVnode +'.vertexUvOne',textureNode + '.vertexUvOne',force = 1)
    mc.connectAttr(UVnode +'.vertexUvTwo',textureNode + '.vertexUvTwo',force = 1)
    mc.connectAttr(UVnode +'.vertexUvThree',textureNode + '.vertexUvThree',force = 1)
    mc.connectAttr(UVnode +'.vertexCameraOne',textureNode + '.vertexCameraOne',force = 1)
    mc.connectAttr(UVnode +'.noiseUV',textureNode + '.noiseUV',force = 1)
    mc.connectAttr(UVnode +'.offset',textureNode + '.offset',force = 1)
    mc.connectAttr(UVnode +'.rotateUV',textureNode + '.rotateUV',force = 1)

2.新建材质节点
shadingNode
例如建立arnold标准材质节点，redshift标准材质节点，UV节点

aiStandard = mc.shadingNode('aiStandard',asShader = 1,n = materialName)
rsMtl = mc.shadingNode('RedshiftMaterial',asShader = 1,n = materialName)
UVnode = mc.shadingNode('place2dTexture',au =1)

3.设置节点属性
setAttr

maya.cmds.setAttr(texturesUsing[textureUsing] + '.colorSpace','Raw',type = 'string')
