FAQs & Issues

Nothing Rendering

• If using URP, make sure XI_URP preprocessor define has been added
• Try adding “XI Render Feature” to URP asset
• Make sure the XIDocument has the Manager field set to a Manager in scene
• If using Shapes adding “Shapes Render Feature” to URP asset

Background Rect is not rendering

• If the background color / border is not rendering but text and icons are, check the XI Standard Renderer component to see if the “Rect Material” is applied

Overflow is not being clipped

• Check if the “Use Clip” flag in the standard renderer config is enabled and if a functioning clip material is assigned

Incorrect height / layout sizes

• Try adding UnityDefaultRuntimeTheme to panel settings

Text is not visible

• Check if the text meshes are being rendered by viewing the scene in wireframe mode or looking at the “Frame Debugger” for the draw calls
• If the proper draw calls are being made: Try making sure TMP font asset being used is rendering properly. If the asset has been accidently modified it might not display properly. Reimport the TMP essentials if necessary.
• If this issue is happening only with the Shapes renderer, try following setup for Shapes Renderer involving modifying Shapes source (IMDrawer.cs)

    }
    

Invalid Image Specified Warning

• This warning message can be seen with Vector Images in UI Builder even if they have the proper references. Not sure if this is a Unity bug but after some combination of reassigning images in UI builder, saving, closing, and reopening again, this error went away.
