I'm using custom source build of 5.1.1
I installed the plugin, clicked on "Add To Viewport" on the WorldUI thing inside of the plugin content.

There is nothing visible at all, no errors.
It does create the View widget, it's ticking (checked by print a string inside the "Tick" function)

I have added
`PrivateDependencyModuleNames.AddRange(new string[] { "Noesis", "NoesisRuntime" });` into ProjectName.build.cs
and #include "NoesisRuntime.h" into ProjectName.h

Also I was following https://www.noesisengine.com/docs/Gui.C ... orial.html

After I added NuGet for NoesisExtensions and then tried to use the style, I got this:

Hi,

The WorldUI Xaml you are trying to use has no content. It's an empty panel that we use to add other content to it dynamically. You can download a zip file with an Unreal project containing multiple samples from the Downloads section here https://www.noesisengine.com/developers/downloads.php

I also create a blend project with a single button, imported the xaml of it and nothing was showing too

Do the examples that come with the plugin work correctly?

Example project works, but I can't see anything in my own project

Weird, but it works with the xaml files from the sample project. idk what's up with my custom one

Are there any errors in the Output Log window?

Nope, nothing

Could you paste your test Xaml here, please, so I can take a look?
