UnitySplats 2.0.0

20261021-1049-46.4294861.mp4

Highlights

Gaussian splats can now be relit by Unity's directional, point, and spot lights with the new Gaussian Relighting component. No proxy mesh is needed.

Added

• Gaussian Relighting component with Volume (default) and Proxy Mesh modes; switching modes keeps both setups.
• Volume mode treats each Gaussian as a small oriented surface, automatically combines up to four affecting lights with Unity-style falloff, and adds soft self-shadowing from an opacity field.
• Opacity-field status and Rebuild Gaussian Opacity Field button in the inspector.

Fixed

• Volume relighting no longer rebuilds its opacity field every frame when the field cannot be built; lighting continues without self-shadows.
• Lower memory use: the opacity field is built in temporary native memory that is freed right away, and renderers using the same asset and settings share one 3D texture.
• Lower GPU cost: lights that don't reach a splat skip shadow tracing, tracing stops once a ray is fully blocked, and per-renderer values are computed on the CPU.

Compatibility

• Renderers in Volume mode are drawn separately, so cross-renderer merged sorting is disabled for them.
• Volume mode samples a 3D texture in the vertex shader (Metal, Vulkan, OpenGL ES 3, WebGL2). Devices without R8 3D-texture support get lighting without self-shadows.
• For large captures on mobile, use Shadow Steps 4–6 and Automatic Light Limit 1–2.

UnitySplats 1.2.0

• Corrected DirectX 11 splat compositing across large camera-depth ranges using full-precision CPU sorting.

UnitySplats v1.1.0

Added

• Added collider-free Scene-view selection using transformed splat bounds.
• Added GPU picking, Scene-control picking, and ray/bounds fallback paths.
• Added selection padding for thin captures and oblique camera angles.
• Added multi-object GsplatRenderer inspector editing.
• Added batch BoxCollider fitting.
• Added hover tooltips for renderer controls.

Changed

• Enabled cross-renderer per-splat sorting by default.
• Moved cross-renderer sorting configuration exclusively to Project Settings > Gsplat.
• Replaced the duplicate brightness controls with one Brightness slider.

Compatibility

• Cross-renderer merging requires compatible Spark assets and the GPU radix path.
• OpenGL, WebGL, Direct3D 11, and other CPU-fallback configurations continue using separate renderer draw calls.

UnitySplats v1.0.1

Fixed

• Fixed Unity 6.5 compilation errors caused by the deprecation of Object.GetInstanceID().
• Updated resource, sorter, renderer, camera and editor caches for Unity's 64-bit EntityId transition.
• Separated the package version from the internal settings migration version.

Documentation

• Added an OpenUPM installation option that automatically resolves Unity.WebP 0.3.22.
