'ply2vrmesh.exe' path - Exporting V-Ray proxies requires ply2vrmesh.exe. It is installed with every version of V-Ray. Transmutr automatically tries to locate it on the machine, but if it doesn't, you need to manually browse for it.
You can get ply2vrmesh even if you don't have a V-Ray license, you can simply install the demo of V-Ray.
