No impression on ad unit that has rotation

[pepperwood998]

Hi I think I found an issue that might affect the flexibility of the immersive ads experience.

I'm using the version 1.4.2 and Google Mobile Ads version 8.6.0

I have a scene setup like this with world space ad units

Each ad unit has an rotation around the Y-axis

• default_1: 0 (deg)
• default_2: 90 (deg)
• default_3: 36.68 (deg)

What I expect the result when testing on Android device is that all 3 ad unit will have ad impression, but only default_1 and default_3 have ad impression. It's also worth mention that when clicking on default_2, the ad still open but the visualizer didn't change to green.

I thought the whole immersive ads is that I can place the ad unit at any positions, with any rotation as long as the camera for the ad unit can view them properly. Please take a look at this issue, thank you very much.

Hello! Actually this is not an issue, this is an expected behaviour.

Impressions are triggered based on the orientation of the camera relative to the world axis, not the placement position or rotation of the ad unit. This occurs in specific world axes like +X and -Z.

In your test case scenario:

If you observe the default_2 ad unit in the Unity editor, when viewed towards the ad unit, it falls under the +X world axis. In this axis, impressions will not trigger. Attached photo for the reference and highlighted it
However, for the remaining ad units, the orientation is under +Z or -X, which is why impressions are triggering for them.

That’s why we suggest placing the ad unit such that, when viewed, it aligns with the +Z world axis to ensure confirmed impressions.

Thank you for replying. I think in the documentation the restriction on the X-axis is not mentioned. It would be crucial to include it.

Sure, we will include it.

So I test a little bit more on the rotation of default_2. I only change its rotation on the Y-axis from 90 to 30.9 and keep everything the same, now I get the impression on it.

I think your wording might be misleading here, since the rotation of the placement here does affect the impression

Impressions are triggered based on the orientation of the camera relative to the world axis, not the placement position or rotation of the ad unit. This occurs in specific world axes like +X and -Z.

The reason I mentioned this is not about placement or rotation alone. Let’s say you changed the ad unit's rotation while the camera is in a static position. If the camera becomes dynamic and you view the ad unit from a different orientation, it changes again, and impressions may not trigger for the ad units.

To conclude, ensure that when the camera is viewing the ad unit, it aligns with the +Z axis, as camera orientation is the key factor.
