Export USD asset using Python

export_config = {
                "defaultExportPreset": "export-preset-generator://doc-channel-normal-no-alpha",
                "exportList": [{ "rootPath": "cymourai" } ],
                "exportMeshTessellation": False,
                "exportParameters": [{
                    "filter": {},
                    "parameters": { "dilationDistance": 16, "paddingAlgorithm": "infinite" }
                }],
                "exportPath": "",
                "exportPresets": [],
                "exportShaderParams": False,
                "exportUSD": False
            }

There is a flag in the export configuration dictionary , "exportUSD". Make that True :).

You can find more python test examples in C:\Program Files\Adobe\Adobe Substance 3D Painter\resources\python\modules\automated_tests (for substance painter version 10 at least).

Hope this helps

I'd like this option as well. The local docs for 10.1.2 do not mention this possibility, but you can substance_painter.export.export_mesh() as USD. Looks like it saves as USDC. No textures, but I'll bet you could convert it to USDA and use the OpenUSD spec to build in your project textures. Non-trivial, no doubt.

I am also interested in a solution  for this  it seems like it hasn't been exposed in  the  json_config dict . or the documentation not updated
