Full Changelog here

1.5.1 - 8/17/2026

Added an option to cache terrain detail data async, reducing spikes when loading new terrains
Fixed BRGIR rendering behavior while the Frame Debugger is enabled
Slightly optimized culling shader
Optimized Terrain Registerer startup (extra optimizations for Unity 6.5+)

1.5.0 - MAJOR UPDATE - 8/9/2026

Switched to a mix of Box/Sphere culling for the instance Culling kernel
Optimized prototype bounding sphere tightness to cull more instances
Added new levels to Occlusion Culling

Loose - The existing mode
Tight - Tightens culling a bit more at the cost of making culling more expensive
Aggressive - Culls even more instances, but might also falsely cull some instances

Added Lossy/Improper shadow culling modes, good for prototypes that cast short shadows:

Lossy/Improper Caster Distance Culling - Culls shadows when a caster is a certain distance from the camera.
Lossy/Improper Caster Frustum Culling - Culls shadows when a caster is outside the camera frustum + padding.

Fixed Lossless shadow caster culling to work with single-cascade directional lights
Improved runtime stats window

1.4.1 - 8/3/2026

Fixed RemoveInstance not actually removing an instance

1.4.0 - 8/1/2026

Optimized the WriteChunk path to be ~4× faster
Optimized more core methods with Burst
(BREAKING) Changed the Terrain Tree instance link API to provide a NativeArray instead of a List
Fixed incorrect legacy light probe calculations

1.3.5 - 7/25/2026

Added new Batched TRS + Color staging pipeline to BRG Registration Tracker
Updated Instance Link Demo scene to use new batched staging pipeline

1.3.4 - 7/23/2026

Optimized SpeedTree wind sampling
Stripped code from UNITY_SERVER builds

1.3.3 - 7/22/2026

Fixed compilation on WebGPU

1.3.2 - 7/21/2026

Terrain Registerer startup is now 3× faster (jobified + Burst data extraction)
Optimized terrain detail chunk streaming
Added profiler markers to ensure all BRGIR code is wrapped
Micro-optimized culling compute shader — removed redundant InterlockedMax
Optimized chunk shadow culling
Fixed incorrect distance density culling

1.3.1 - 7/17/2026

Added "Force Disable Shadows" to BRG Prototype Group (useful for a "Grass Shadows" graphics option)

1.3.0 - MAJOR UPDATE - 7/16/2026

Added Draw Command Filtering — draw commands are now only submitted for prototypes that exist within a chunk visible to the sub-view. Reduces draw calls and improves CPU performance on large scenes, especially with multiple shadow-casting lights.
Improved shadow culling tightness and efficiency for slightly better GPU performance
Added New editor-only debugging toggles
Fixed Terrain tree chunk bounds were way oversized
Fixed Occlusion culling in VR now properly uses a per-eye depth pyramid
Fixed Occlusion culling in HDRP when using hardware dynamic resolution
Fixed incorrect occlusion culling at low resolution

1.2.1 - 7/13/2026

Added option to skip BRGIR rendering for specific cameras
Added tree chopper and planter demo
Fixed PC VR rendering on Vulkan when the Mobile Patcher is applied

1.2.0 - 7/8/2026

Switched pool size to hold 16 instances instead of 64. This will result in less wasted memory for sparse instances. If you changed Max Pools Per Chunk or Initial Num Pools, you'll need to set them again after the update to be 4× as high as your previous values.
Optimized GPU uploads
Faster legacy light probe sampling

1.1.4 - 7/1/2026

Fixed occlusion culling + debug info on Unity 6.5+ (thanks @saini)
