MtoA - Import arnold shader (ass/mtlx) from file

[itayassouline]

Hi!

I would like to build a script that takes a file from the computer (i dont care if its ass or mtlx)

and imports it to the hyper shade like this menu tool: .

i know about

cmds.arnoldExportToMaterialX(filename="/path/to/myfile.mtlx", mtl=True)

to export,

but i cannot find an import command.

Thanks!

arnoldImportAss

def arnoldImportShaders():
    global defaultOperatorsFolder
    if defaultOperatorsFolder == "":
        defaultOperatorsFolder = cmds.workspace(q=True,rd=True, fn=True)

    objFilter = "ASS File (*.ass);; AXF File (*.axf);; MaterialX File (*.mtlx);; USD File (*.usd *.usda *.usdc)"
    ret = cmds.fileDialog2(cap='Import Arnold Shaders',okc='Select',fm=1,ff=objFilter,dir=defaultOperatorsFolder) or []
    if len(ret):
        defaultOperatorsFolder = ret[0]
        cmds.arnoldImportAss(f=ret[0], mask=ai.AI_NODE_SHADER)
