Here’s the basics of my custom rendering. I need to have the Frustum and Entitys Transform3D in my custom RenderNode.

The setup is like this:

```auto
<App Theme="Basic" Background="#eeeeeeff">

  <RenderNode>

        <!-- some ui elements on top it -->

      <Scene Camera="CameraEntity">

          <Entity ux:Name="CameraEntity">
              <Frustum FovDegrees="120" ZNear="10" ZFar="10000" ux:Name="CameraFrustum" />
              <Transform3D Position="0, 0, 0" RotationDegrees="0, 0, 0" Scaling="1, 1, 1" ux:Name="CameraTransform" />
          </Entity>

          <MyRenderNode ux:Name="MyRenderNode" CameraFrustum="CameraFrustum" CameraTransform="CameraTransform" />

      </Scene>

</RenderNode>

```

And MyRenderNode is:

```auto
<RenderNode ux:Class="MyRenderNode" ux:AutoCtor="false">

</RenderNode>

```

And its class contains

```auto
public Frustum CameraFrustum {get;set;}
public Transform3D CameraTransform {get;set;}

```

But compiler gives when trying to use the preview:

```auto
'MyRenderNode' does not have a property called 'CameraFrustum' - MainView.ux(12:1):E

'MyRenderNode' does not have a property called 'CameraTransform' - MainView.ux(12:1):E

Errors were encountered while building the project - (0:0):E

```

It works just fine when building to DotNetExe with

```auto
fuse build --target=DotNetExe --run

```

What’s wrong here?

Hey, please see this [post](https://www.fusetools.com/community/forums/permalink/14c3a249-98bd-41da-9c27-ddc281f4b35a)

It explains how you can use custom controls in preview, and limitations. Feel free to ask questions if any.

I also fixed your posted project so that it works in preview using my above guide 🙂

[RenderNode](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/iAwkTbgT4Tkr-legacy-files-2IwJIifn7Wyel8yH-oiVFR6l9uSXGoKMp5c3o16w7.zip)

Run `fuse preview RenderNode/Startup` to test. You can use that as an example on how to setup a project that can preview custom controls.
