Happy Friday BKD Productions,
If you look at your Epic Games > 4.10 > Engine > Plugins folder, you’ll see that there are many plugins installed into the engine. If you click on Plugins > Marketplace, you’ll see that Substance is included. Plugins installed into the engine from Marketplace are going to show up under ‘Installed Plugins’ as well as the Marketplace folder.
Looking closer at what you’re talking about, Kinect 4 Unreal Introduction isn’t a plugin, but it needs the Kinect SDK 2.0 plugin from: http://www.microsoft.com/en-us/download/details.aspx?id=44561 to be installed. But all you should need to do is go to Marketplace and type in ‘Kinect 4 Unreal’ and then it’ll say ‘create project’. Once you’ve created a project, after the SDK is installed, it should work accordingly.
Now, if you have errors popping up from loading your project, I will need to see the full error log and/or any error prompt pictures to be able to assist you further.
Thanks!
