Hello,
I am using Unity’s UI Toolkit to create my UI. Recently, I have been trying to render a game object in front of a UI Document, but after trying several approaches, I haven’t been able to achieve the desired result.
- I attempted to use a RenderTexture to render the game object with a camera, then set that texture as the background image of a Visual Element in the UI.
- I also tried modifying the UI camera’s depth value to ensure the game object renders in front of the UI.
However, I am encountering issues where either the UI Document or the game object doesn’t render correctly, or the game object is rendered behind the UI. How can I render the game object properly in front of the UI Document?

Question:
- What is the most suitable method to render a game object in front of a UI Document?
- Are there any specific settings or considerations for the RenderTexture or camera configuration for UI rendering that I should be aware of?
I would appreciate any help or guidance!
I have used a render texture multiple times for this with no problems, so not sure why it’s not working for you. It sounds like you may have had visual elements in front of the one you’re setting with the render texture background?
In how far? If that version draws it in front of the UI then it’s probably just related to Camera settings, eg Postprocessing or FOV.
When you render that object, you are using masks to filter out other content? Just asking in case you happen to render the object and also draw the UI into the render texture. This would mask the behaviour and look like the object is drawn behind the UI when the render texture in fact is drawn normally on the UI.
I can see the game object, as shown in the attached image, but it is being obscured by the UI image.
The sub-camera is set to Solid Color with RGBA (0, 0, 0, 0), and I’ve configured the layer settings to render only the game object.
However, the game object is still hidden behind the UI image.
How can I resolve this issue?
Both the mushroom and the character are drawn via VisualElement right?
What if your replace the render texture with an existing texture? Perhaps the sort order of these elements is simply incorrect and you just need to push the mushroom to the background. I’m not sure how UI Toolkit layers overlapping images though, may be affected solely by parent-child relationship.
I resolved the issue.
I had mistakenly enabled the UI Document twice, which caused the game object to be obstructed.
Thank you for your response.
