Unity 6000.6 fixes panning skyboxes that only used the left eye in multi-pass. Understand why eye testing is essential in immersive media.

Direct answer

Unity 6000.6 fixes a bug where panoramic skyboxes in the Universal Render Pipeline could appear monoscopic in multi-pass mode, using only the left eye image even when 3D layout was configured. The defect reduces depth and may cause discomfort or editorial inconsistency. 360 video projects and immersive environments must separately validate each eye, projection, stitching, horizon and scale after updating the engine.

Two equal eyes remove disparity

If both receive the left image, the scene may appear flat and misaligned with 3D elements. The fault does not always appear on the editor's monitor.

Projection and sewing remain separate

Correcting eye selection does not resolve crooked horizon, seams, scale, or incorrect metadata. The capture and export pipeline needs its own control.

Multi-pass deserves regression case

Even projects that use single-pass can fall into another path by device, configuration or resource. Include supported modes in automated and visual testing.

Comfort is a quality criterion

Inverted, vertical or excessive disparity can generate fatigue. Review nearby points, movement, transitions, and duration with representative people.

Nexus Reading

Immersive media needs to be validated at the destination, tit for tat. A setting marked as 3D does not prove that the runtime delivered correct stereoscopy.

FAQ

Did the error affect any skybox?

The note mentions panoramic skyboxes in the URP, 3D layout and multi-pass mode.

How to notice the failure?

Capture or inspect each eye and confirm that the views match the correct stereo pair.

Is updating Unity enough?

Correction is necessary, but projection, stitching, scale and comfort still need validation.
