MicroSplat 3.9.22

- Removal of direct substance support (due to substance API changes)

- Terrain Blending lighting matrix blend can be controlled indepently of texture blend

- Fix to per texture triplanar contrast

- Fix to distance resampling when stream override is used

- Fix duplicate syncing of terrains when many terrains are used

- Reduce memory usage when packing textures

- Better tab controls on FX painter when many modules are present

- Fix to various truncation warnings

MicroSplat 3.9.7

- Streams now tintable

- Fix to procedural texturing sample stripping on windows

- Fix to trax tessellation displacement when using only snow tracks

- Documentation buttons readded to every module

MicroSplat 3.9.0

- Massive refactoring of internal use of texture samplers. A total of 20 samplers were removed from the system, and I don't think it's possible to exceed the hardware sampler limit (16) anymore. Unfortunately this required bumping the major version, since it affects almost every module.

- (internal cleanup) Removed surface shader legacy cruft, mostly using modern declarations and sampling conventions now.

- Fixed a few places where textures were being wrapped instead of clamped, causing potential seems between terrains

- Texture Selection Displays now shows overriden layer name when layer is overridden in Texture Array Config

MicroSplat 3.8.13

- Fix to distant resampled triplanar normals

- Snow amount would get modified by the angle filter, causing the snow to fully appear much too early (around 0.2 in the demo scene). This now always spans the full range from 0-1.

- Better integration of snow with tessellation. Displacement starts a bit later to give time for snow to visually appear before build up. Displacement now fills in the low areas first, then eventually flattens the terrain when enough snow has built up.

- Fix to compressor to make sure compression is applied in build on newer unity versions

- Remove per-pixel normal setting on digger shaders

MicroSplat 3.8.12

- Fix to per-texture controls for second/third noise normal in anti-tiling module

- Fix to triplanar when using blend surface normals and tessellation

- Fix to microsplat compressor file format not being linear

MicroSplat 3.8.0

PLEASE DELETE THE CURRENT VERSION OF MICROSPLAT BEFORE INSTALLING

- MicroSplat now delivered as a Package instead of as an asset. This means that it can be found in your Packages folder.

- Examples are no longer imported as part of the module. Instead, you can install them by selecting the module in the Package Manager and unpacking the sample you want to try.

- MicroSplat now uses assembly definition files. If your code uses assembly definitions, you will have to create appropriate references to MicroSplat. Note that all modules use assembly references to inject themselves into the main MicroSplat assembly definitions, so you do not have to account for module usage.

- Note that due to the new assembly definition files, some 3rd party assets will need to be updated to work with MicroSplat again. If you are using lots of third party integrations, you may want to wait to update until they have been updated as well.

- The minimum Unity version for new MicroSplat development is now 2019.4, previous versions are still available for 2017+.

- The Ultimate Bundle can now be downloaded as a single download instead of as separate modules!

MicroSplat 3.794

- Render Baking now working in Standard and URP

- Unlit option for the shader in debug modes

MicroSplat 3.7

The entire system has been rewritten to run off the Better Shaders framework. This is a pretty massive change that fixes many slight differences and bugs between the various render pipelines, making it much easier to fix issues across all the pipelines at once.

Note that Unity's Package Manager is completely broken in most versions of Unity, will show that it has the latest version, but instead install older versions. To fix this, please delete the asset store cache before downloading any assets, otherwise you will most likely not get the latest version.

MicroSplat 3.6

**MANUAL UPDATE STEPS MAY BE REQUIRED**

If you are using terrain blending, dynamic streams/lava, Mesh Terrains, or per-pixel normal, you will need to update the terrain descriptor by clicking Update on the MicroSplatTerrain component next to the terrain descriptor.

- HDRP now supports tessellation

- HDRP now supports Vertex Mesh Workflows

- HDRP now supports Digger Integration

- Option to use Surface Gradient framework for normals instead of traditional normal blending

- The terrain descriptor is no more, all hail the terrain descriptor. The terrain descriptor is now a world space normal map, reducing its memory use in half from the previous format. It also now doubles as the per-pixel normal map, saving you more memory if you were using it as well. The height map is now read directly from the terrain, as it is available in both instanced and non-instanced modes.

- Per Pixel normal maps are now stored in the same format Unity uses, so that the code which samples them does not care if they come from Instancing or are manually generated. Unfortunately there is an issue in Unity in that grabbing the instanced normal map and trying to use it doesn't work until the second frame, if this becomes possible to fix, a terrain descriptor won't be necessary when instancing is enabled.

- Terrain Blending can now work over Mesh Workflow meshes which use the Combined or Splat modes

- Mesh Terrains now create a per-pixel normal map texture automatically when Draw Instanced is enabled on the terrain, to better match the original terrain.

- Mesh Terrains also serialize out a special height map texture when dynamic lava or streams is used on them.

- Vertex Painted meshes can use tessellation in URP and HDRP

- Biome and Tint masks are no longer autogenerated by the Terrain Painting system when they are not found on the component. This would create issues when a user assigned a tint map to the material (but not the component) and the terrain painting system would suddenly create a new tint map for them and assign it as an override. Now you have to press a button to create one.

- Custom texture importer for HDR texture types, can be used to serialize in/out native textures without going through Unity's broken EXR pipeline (which gamma corrects linear textures)

- Mesh Terrains now set proper shader types when using the generate separate shader option

- URP/HDRP properly detected again when converting terrains

- Fix to SRP batcher compatibility

- Fix to normals in HDRP when using triplanar texturing

- Fix to stereo VR rendering in URP when tessellation is enabled

- Fix to polaris module to make multi-terrain workflow better.

- Many small fixes, optimizations, and code cleanups

MicroSplat 3.53

- Terrain Blending now uses height/normal map from terrain instancing when Draw Instanced is enabled. This allows you to not have to have a terrain descriptor in these cases, saving memory and allowing for runtime terrain blending with things like Map Magic. Note that you will still need a terrain descriptor for dynamic streams/lava or mesh terrains.

- Fix to terrain blend override not showing when terrain can't be found

- Fix to procedural texturing biome mask not working when using only one biome mask

- Fix to Terrain FX Painter biome mask painting

- Fix to anti-tile array sampling first texture in array when in non-triplanar mode

- Fix warning about CTemplateMaterial

- Fix to Draw Instanced in URP when terrain blending is enabled

- Disable Tessellation and parallax on terrain blended objects (this got removed in a refactor by mistake)

MicroSplat 3.5

- Decal module support

- LUTs generated by per texture property data and procedural texturing are now exposed as sub assets of the scriptable objects. This paves the way for non-component backed MicroSplat shaders, such as simple object shaders.

- Fix to Biome Mask 2 in Procedural Texturing module not combining with the first biome mask as expected

- Fix to snow not rendering correctly on mesh terrains

- Wrap mode option for global texturing

- Optimizations to procedural texturing

- Refactor of compiler to better support additional shader outputs

- Warn when texture count > max texture count

MicroSplat 3.47

- Added ability to paint the procedural texturing's biome mask(s) in the terrain fx painter

- Biome mask overrides added to several backing components

- Height noise can now be procedural or texture based

- When layer scale is copied back to the terrain layers, it is correctly computed between global and per-texture UVs, which makes it match when removing MicroSplat from a terrain

- Small fix to normal strength on distance resampling

MicroSplat 3.402

- Global textures can now use Quadratic Blending for better sampling of textures - see docs for example

- Fix to origin shift so it only does position

- Fix to noise height when triplanar and tessellation are enabled

- Fix to null ref when working with substances
