Hi, open up the “CitySample.uproject” (or whatever project name you have) in a text editor, search for “Mass” and change the values to “true”. If the Mass ones below aren’t there, add them.

			"Name": "MassAI",
			"Enabled": true
		},
		{
			"Name": "MassCrowd",
			"Enabled": true
		},
		{
			"Name": "MassEntity",
			"Enabled": true
		},
		{
			"Name": "MassGameplay",
			"Enabled": true
		},```

Is it possible you disabled other plugins as well? Try enabling all plugins contained in the uproject file.

Wohoo…Thank you so much @RecourseDesign it worked for me. enabling the the plugins by changing from false to true in text editor, of uproject file. Thanks a ton. :heart:

It would be also helpful if you can help me to understand how to disable the simulated characters and vehicles in renders which comes along with the pack default. i dont want to see the default simulated characters which comes along with the city sample pack which i have downloaded from Epic games market Library.

Thank you :slight_smile:

No problem!

That may be good as a separate question - someone with more experience working with them may be able to answer that.
