V2.73

-Fix small dumb bug preventing game from building. Sorry.

V2.72

-Hopefully fixed some bugs that sometimes caused the density from a parameter map to not be respected outside of paint/play mode and other weird density related behaviour

-Increased severity of the warning about duplicate grass renderers because it can cause bugs and bad performance

-Fixed some bugs with frustum culling and added some safeguards to prevent crashes when enabling it hopefully

-Fixed it so that the shaders no longer spit out dumb useless warnings

V2.7

-Add crossfade support when using grass LOD meshes

-Chunks with a baked density of 0 are no longer considered when culling

V2.67

-Fix some weird errors with the mesh highlighting when hovering over grass meshes in the list or when painting

-Finally fix it so that when you drag an object into the terrain transform slot it will appropriately switch to mesh render mode if it's a mesh and it was previous set to terrain, and vice versa

-Fix URP deferred light layering error in newer URP versions

V2.66.6

-Fix a small oopsie with the reversion of urp detection where the inspector thinks it's in urp mode when it really isn't and mucking things up

V2.66

-Fix some situations where some a compute buffer was not properly reset, probably causing a bunch of other issues

-Other fixes to multi terrain issues in the editor

-Fix bug where if one grass mesh appeared red because of missing assets, all the others under it would as well

-Revert urp detection to old method with manual prompt

-Should fix warnings about memory leak or GC disposing of compute buffers (this was only an issue in the editor)

V2.65

-Cpopy

-Fixed bug painting multiple grass meshes on same object transform, now will paint selected grass mesh if there are multiple on the same tranform

V2.64

-Add slope threshold fading to scale grass down near the slop threshold

-Fixed an error that could be thrown when using the optimized shader

-Fixed a shader compilation error in certain situations

V2.63

-Fixed some issues with URP causing grass not to show up in builds hopefully

-Fixed potential issues with colors causing bright glints with post processing bloom

-Added height offset parameter to the material

-Added texture alpha multiplier to material

-Added a terrain slope angle threshhold for spawning grass

-Added a check to the material pipeline checker to make sure it can't run outside of the intended example scenes

-No longer need to manually enable URP support on the GrassFlow Renderer component

V2.61

-Fixed inaccurate normals on grass causing weird patterns and bad surfact adhesion sometimes

-Fixed bug in normals when not baking additional data that could cause upside-down grass

V2.60

-Switching in and out of paint mode no longer has a desync with grass density when using bake density and dynamic paramter map is off

-Fix small bug of grass type painting not being accurate when baking grass data

-Fix bug when the scene does not have a main camera

-Implement _GlobalBias for mipmap bias in URP

-Fix issue of wind sometimes disappearing in the editor until reloading the scene

V2.58

-Reduced compute work group sizes to fit within 128 max invocation spec for vulkan.

Some devices would fail to compile certain compute kernels because of this. Oops.

V2.57

-Fixed errors when trying to add a GrassFlowRenderer component directly.

-Multiple renderer warning can be dismissed.

V2.56

-Improved ability to use URP SSAO render feature (no longer requires after opaque)

-Added a DepthNormals pass for things that require it instead of a depth only pass

-Changed default render queue on URP to transparent when not using a depth pass (to avoid no grass showing when using depth priming, if not using depth priming and not using a depth pass I'd still probably recommend using Alpha Test on the render queue.)

V2.55

-Greatly Improved loading times for terrains (a couple orders of magnitude probably 💦).

-Implemented a system to dynamically load only visble chunks which should allow large terrains to actually be usable in the new system without completely destroying memory usage.

-Added a setting to not bake map data into grass data, this should allow you to reduce vram usage by about 37% at the cost of some potential performance if you need to sample the maps in the shader.

V2.51

-Slight fix to URP deferred

V2.5

-Woo

Alright so this update brings some pretty big changes, most of which are really good, but it also removes some older stuff I felt like isn't really worth having around anymore.

So first the removals:

-Geometry shader no longer supported

-Tessellation shader no longer supported

I don't think many people used tessellation as it was kind of an experimental technique. And the geometry shader doesn't really have any advanteges other than dynamically scaling number of segments for bending grass in the distance. But the new system can functionally replicate this and more anyways.

So the cool new stuff:

-Individual meshes/material LODs at different distances

-Optional compute based frustum culling, may be faster in some cases

-Many optimizations to shader performance

-Many new material settings for optimizing performance even further (especially for mobile)

-All lighting functions including shadows and specular are now supported in vertex lit

-Added an option not to expand bounds horizontally

-Can now manually control number of LOD steps separately

-New material option to use vertical scaling for LOD fade-in

-I think vulkan was broken before but should be fine now

-Hovering over a grass mesh in the inspector now highlights the mesh

-Ctrl+A now selects all grass meshes

-Support for URP Forward+

-Support for URP screen space shadows

-Better normal mapping support, especially with specularity

-New experimental fake self shadowing feature

-New limited batching drastically reduces draw calls

-Added ability to control variation color tint

V2.24

-Fix deferred colors having permanent intense fog applied

-Fix other fog related issues

V2.23

-Fix variable accidentally removed in shader when using bending

V2.22

-Fix accidentally included assemblies

V2.21

-Fix openGL type map errors when painting is enabled

-Fix openGL terrain normal maps being broken

-Fix mobile platform fog not working

-Reduce computer buffer usage in custom mesh mode in order to be able to run on most mobile devices

-Moved to procedural rendering function, performance should be a bit better and easier to update transforms.

V2.19

-Fix regression caused by 2.17 causing vertices to do strange things when using the mesh shader

-Add global wind strength property to the material

V2.18

-Fix to handling material keywords to make sure there are no issues in builds when using material instances

V2.17

-Fix normals for "Seek Sun" feature on the material so it doesn't point all the wrong ways.

-Fix bug with ripples and forces where forces would not work unless ripples were also present. Also fixed potential jittering with ripples.

V2.15

-Fix issue with "Discard Empty Triangles" when using multiple grass meshes on same renderer

-Fix occasional error in terrain mode

V2.13

-Fixes to make using scaled transforms (non 1,1,1) behave a lot better

-Fix error in URP shader causing depth not to compile and maybe preventing builds sometimes

V2.12

-Changes to terrain mode to make it possible to discard individual triangles based on the density map, rather than only entire chunks. This should make terrain mode more efficient when using a density map to paint out areas of the map.

-Separated secondary wind noise settings from main wind so it can be more controllable and give nicer effects, it also more confusing now, sorry.

-Added warning for using multiple GrassFlow Renderers

-Reorganized some things to be more clear

V2.1 - This stuff is cool, trust me

-Now grass can be created using custom meshes!

-Specular highlights

-Normal mapping

-Some small lighting bugfixes

-Minor QoL changes

V2.02

-Hopefully white grass in builds using the deferred shader is fixed now. Oops.

V2.01

-Minor updates to make creating a renderer at runtime better.
