3DMAX换贴图插件

每当材质需要替换贴图时都要一个个打开材质，比较麻烦，这里直接选择模型进行一个贴图的替换，主要针对mtlstandard和VRAY材质的diffuse和normal贴图的替换

废话不多说直接上代码

/*先定义一个函数用来收集VRay材质和MTLstandard材质*/

fn ti_huan=
(
--bitmap_path=getopenfilename  caption:"" filename:"" types:"JPEG (*.jpg)|*.jpg|TIFF(*.tif)|*.tif|BMP (*.bmp)|*.bmp|Targa (*.tga)|*.tga|PNG (*.png)|*.png"--gets
global m_mat=#()
global v_mat=#()
d=for b in selection where classof b.material==standardmaterial collect b--vraymtl材质
v=for b in selection where classof b.material==vraymtl collect b
)
