This release includes the following significant changes:

Mipmap support for local textures

The Source Textures component has a new Mip Mode option that controls how a Local Texture's mip levels are written into the layer's swapchain image:

• None (default): the swapchain is created with a single mip level.
• Copy From Source: every authored mip level is copied directly from the source texture. Use this when the source format is compatible with Graphics.CopyTexture.
• Auto Generate: mip level 0 is blitted into the swapchain and the lower mip levels are generated automatically. Use this for sources that cannot be copied directly, such as compressed or cross-format textures.

Note

Mip Mode requires Unity 6000.7.0a4 or newer and OpenXR Plugin 1.19.0-pre.2 or later.

Dynamic textures

The Source Textures component has a new Dynamic Texture option. When enabled, the layer's swapchain image is rewritten every frame, so textures whose contents are updated externally on the GPU (such as native plugin or AHardwareBuffer-backed Texture2D objects) no longer appear static.

Note

Dynamic Texture requires OpenXR Plugin 1.19.0-pre.2 or later.

Equirect vertical angles are now measured from the equator

The Equirect layer's Upper and Lower Vertical Angle are now measured from the equator (positive above the equator, negative below). A full sphere now uses an Upper angle of +90 and a Lower angle of -90, instead of the previous +90 and +90. Existing layers are upgraded automatically.

Other changes

• The minimum supported Unity Editor version is now 6000.0.
• The Default Scene Layer is now serialized into the scene (persisted in the scene file, still excluded from builds) instead of being recreated on load.
