I solved this problem by below steps
- copy the scripts folder (“Quixel.ms” in this folder) from C:\Users\xxxx\AppData\Local\Autodesk\3dsMax\20xx-64bit\ENU\scripts and place it in my “Documents” folder for instance;
- open the “Quixel.ms” file (if you cannot file “Quixel.ms” file scripts folder you need create it)
- paste python.Execute “filePath = r’E:\Megascans Library\support\plugins\max\5.5\MSLiveLink\MS_API.py’; exec(open(filePath).read(), {‘file’: filePath})” and save it. (you need to change the position according to your “MS_API.py” location)
- In 3DS, Customize/Configure users and project paths, relink both “additional scripts” folder that is now under “Documents”
