trying to use a material with a shader as an hider material. The object should cover the object behind it and the camera image should be visible.
Often used on portals or on your smartphone.
Unfortunately it doesn’t work for me. Android and IOS simply show the object in white.
It looks correct in the Unity Scene. It is black in the game window and white in AR mode on the smartphone.
My material has a DepthMask and the material has the Export Lable

Hi, are you using the URP stencil renderer for this?
Hello Sabrina,
It sounds like the issue you’re encountering is with the shader and material setup for rendering AR content where a virtual object should serve as a mask to display the camera feed, commonly known as an “hider” material.
To troubleshoot the problem, consider the following steps:
Export Label for your material is properly set so that Needle Engine recognizes it and includes it correctly in the exported project.Since you mentioned the issue does not occur in the Unity scene or game window but manifests on the smartphone in AR mode, it’s very likely the problem is tied to platform-specific shader compatibility or incorrect material settings for web/AR environments.
Normally, checking the log output on your smartphone when running the AR session might provide more insights and error messages that can guide further investigation.
If there is a more specific question or if you have a code snippet or error message you’d like assistance with, please provide further details so I can offer more targeted help.

“It look black in the game window” refers to the browser or the Unity game window?
the Unity game window

like on the screen shot, on the left the case i want on the right the game window

If the unity game window looks wrong already it will most likely not magically work in the exported scene.
I think what you’re trying to do here is creating a occluder and not a stencil effect. What you could use for the web is add a shadow catcher component and set it to occluder for this
Note that this won’t work on iOS AR tho (only android)
OK, I’ll take a look, thank you

Is there any more information about this? Or how exactly do I have to use it? If I just drag the script onto the object nothing happens.

This effect is currently not displayed in Unity - but you’ll see it in the browser
mh doesn´t work for me:
