Since Houdini 18.5 (and Python 3) is not officially supported by Quixel, I have modified the official MSLiveLink v4.4 to be able to run inside Houdini 18.5 Python 3.

Currently, I only tested it to load Megascans 3d assets for Mantra successfully, but nothing else. There might be other Python 3 modifications that I missed. Please report if any issues.

The Python 3 modifications are the following:

1. Updated all implicit modules import to explicit

from Utilities.SettingsManager import SettingsManager

--->

from .Utilities.SettingsManager import SettingsManager

2. Updated all metaclass declaration
class SettingsManager:
      __metaclass__ = Singleton
--->

class SettingsManager(metaclass = Singleton):

3. Updated SocketListener.py to emit string instead of bytes
self.Bridge_Call.emit(self.TotalData)
--->

self.Bridge_Call.emit(self.TotalData.decode('UTF-8'))

  Hi Kelvin Cai

  Thanks for the report.

  Please note that the plugin support for houdini 18.5 is being worked on. However, we don't have a timeline for it, at the moment. Thank you for sharing this workaround. I'll test this at my end and see how it goes. :)

  Best, 
  Urooj

  Nice that you support quixel on your own. Looks like quixel is giving up on Houdini.
  
  I tried the Python 3 MSLiveLink. The UI Option is working now and no more Port problems from Quixel Bridge. But I got an error here when exporting in Houdini Console..

  File "G:/Quixels/Bridge_Library/support/plugins/houdini/4.4/MSLiveLink/scripts/python\MSPlugin\Utilities\AssetData.py", line 57, in getImportParams
  basePath = importOptions["UI"]["ImportOptions"]["ObjPath"]
  KeyError: 'ObjPath'

  Hello,

  You can download Megascans Plugins within the Bridge application. 

  In the top bar click Edit>Manage Plugins & click on the download icon next to the relevant tool.
