Considering a lot of the modules? The Terrain Collection is now available offering 11 modules at a discount.

The Ultimate Bundle is also available with 18 modules at an even greater discount.

MicroSplat has custom integrations for many popular assets, including MicroVerse, Vegetation Studio, Enviro, Weather Maker, Vista, and Map Magic. MicroSplat is also compatible with terrain generation systems like World Creator, Terrain Composer 2, and Gaia.

MicroSplat is unbelievably fast, often several times faster than competing shaders with the same feature set turned on, and is optimized for both high end and low end hardware. MicroSplat uses a unique shader generation system, so all features compile out and have no cost when not in use, and only the features you want need to be purchased. Note that MicroSplat is not a subset of MegaSplat, but rather a much more advance sequel

- Enforce that the propData object assigned to the terrain is the same as the one the material will find.

- Fix to texture cluster modules compile error in cluster3 mode

- Fix to terrains getting a max texture count of 24 when they should be 16 on conversion

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 3.8.14

- Added "TerrainCompatible" tag to shaders so Unity 2021 doesn't put warnings in the terrain editor

- When using the slope filter in terrain blending, the normal from the terrain is only taken into account on the blend area, not on the tops of objects which are just recieving terrain texturing

- Flip Mesh Workflow normals to match unity standard orientation

- Force array to have 1 texture in it if no textures are provided on conversion

- Cleanup to some trax code in HDRP

- HDRP GI emission flag added

- Fix to per texture rotation of UVs in tessellation stages

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 per texture noise normal strength for noise normals 2 and 3

- 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
