[Released] Advanced Terrain Grass

windows x86_64 // multiple unity versions 2019 & currently 2020.1.15
IL2CPP (but mono the same)
The built in render pipeline

 

hmm, i just gave it another try:
unity 2019.4.23f, windows x86_64, mono and legacy deferred - i used the full demo 02 and everything just works fine.
do you get any errors?

 

Maybe its not even ATG maybe its something else, the problem with the segfault it gives no error what caused it.
I suspect ATG cause it was giving errors > a year ago,
note I have changed the shaders a little to add bending to the normal pipeline

I'll download the new version of ATG and see if that fixes it.

EDIT: Still no go, I built the demo2 from 1.33 and that works so relax mate, its prolly something else, I'll have to dig into it some more

 

looks cool!

 

help me, i made an android mobile game and installed ATG on my terrain, but on some cellphones the grass looks big even though the grass is small

 

doesn't look as if works at all: se ethat there is no randomness in the grass. it looks like just one grass instance per cell – which most likely indicates that the shader does not work.
the graphcs api must support instanced indirect.so vulkan or lastest opelgles should be fine. older version may not be supported.

 

i am using this, should it be replaced with vulkan ?

 

try vulkan, yes.

 

An HDRP preview package is added and available now.

 

Hi I recently got your ATG asset and setup some terrain with grass. I can't see anywhere in the documentation to make the stylized/BOTW type grass like you've got in one of your videos. Does your package come with the shaders (etc) for this (ideally in URP)? Thanks

 

hi!
the URP 10 + packages only contain updated shaders. but the both "urp support" packages:

• ATG_URP_7.1.7_Support.unitypackage
• ATG_URP_7.2_Support.unitypackage

should contain the stylized demo you mentioned. the shader used here is just the "regular" atg grass shader.

 

Hi, I'm trying to combine your asset with World Streamer 2, at the beginning everything loads correctly and no problem, but after switching to another piece of terrain the options reset and the grass is rendered at a very short distance again, maybe some suggestions what is the problem here or maybe how to untie it?


But funny thing, only grass is missing, rocks and all the time.

 

i am sorry, but i do not have any experience when it comes to world streamer.

hmm, i am not sure if i get this properly: options are reset? which options?

 

First peace of terrain leaded with grass manager and we can see grass everywhere cull distance set on every terrain is 1000
Orange line tells where first peace of terrain ends

after leaving the first part of the terrain, the render distance of the grass changes

Also i see how debug.log changes from

to


and maybe you know why asset cant remove terrain?

 

looks like the settings on your terrains do not match?

 

because the grass manager depends on it. you will have to disable/destroy the entore game object. not only the terrain component.

 

On every terrain setting are same

 

Maybe i will try contact someone from streaming asset, becouse on the other hand on scene where i got only world with grass manager everything works perfectly fine.

 

a grass culling distance of 1000m might a bit over the top... depending on your grass density this will need a lot of vram.

 

Hey, its again me. Do you have any idea why im getting this error almost every second?

But while in playmode, when i switch to scene view and click on terrain that is cousing this error, it stops and works perfectly fine.

Im looking for some suggestions what is happening, and maybe sobie idea how i can fix it.

 

that line number does not lead to anything meaningful when i look into latest.
anyway: do you use saved terraindata and are you sure it is up to date?

 

Okey! saving terraindata fix it, thx!

 

Hi, Currently having this error for some reason

 

looks as if one of the materials is not set ptoperly.
the grass manager inspector should inform you about this.
if not change to debug mode and hae a look at the v_mat array. its length has to match the number of assigned prototypes and all entries have to be filled.

 

Thanks, Fixed it!

 

Will this be updated for URP 12 and it's deferred mode?

 

i will have to look into this.

 

Thanks. I did get URP 12 work in forward after changing this line from META pass:

Code (CSharp):

1. #pragma fragment UniversalFragmentMeta

into

Code (CSharp):

1. #pragma fragment UniversalFragmentMetaLit

from all three URP shaders. (URP 12's own Lit had the same change: https://github.com/Unity-Technologi...r-pipelines.universal/Shaders/Lit.shader#L335). Haven't looked into deferred passes myself.

As extra note: URP's new depth priming option seems to break the rendering as well.

 

thanks for the heads up. i will have to look into urp12...

 

version 1.35 is available!

# added URP 12.1 package.
# fixed punctual lights not being rendered properly in forward if compute is disabled.

 

version 1.3.5 nw officially supports URP 12.1.

 

Awesome! Thanks for the quick fix, will give it a go

 

@larsbertram1 actually, the store update misses the ATG_URP_12.1_Shaders.unitypackage (12.1 README is there though), I also verified it's also not listed on the store packages package contents list either (so not an issue on my end not importing it).

 

ups! should be fixed now.

 

Now it works, thanks Anything one could do for that urp depth priming with forward mode or is it out of reach for this type of asset?

 

depth prepass (who the fxxk called it "depth priming"?) works perfectly on dx11.

 

Yeah it's a weird name alright I found that depth prepass set to Forced does work if I have SSAO or Decal renderer feature enabled, otherwise it completely breaks the rendering when I hit play in "Full Demo URP" -scene. I guess there's something not initialized in such combination (not necessarily related to ATG in any way).

 

ah, i focused on the new rendering features which rely on the depth normal pass. turned out the the depth pass was missing a tiny bit of code...
the fixed version is online. so just grab it and let me know if it works for you as well

 

Has anyone ever come across an issue with the standard unity grass rendering alongside the atg grass?

 

atg will set the detail distance to 0. so no standard unity grass in play mode at all.

 

Hey im trying to build controller that changes render distance in runtime. Im using RefreshGrassRenderSetting at this poit, and it works fine. But when i load new chunk of terrain all setting reset, do anyone have idea how can i onload change the rendering distance? and why it is not working?



with this i get error


null reference in culling group in GrassManager


any suggestions how to fix it?

 

are you sure that the cullinggroup is already created for the new loaded terrains?

 

Okey i figure it out, thx do oyu have any idea how i can change shadow casting mode in runtime? for each prototype and changing it with refreshing some kind to instatnly saw the resoult?

 

this might aleady do the trick, yes.

 

just had a quick look into the code:
the grassmanager script contains a bunch of arrays which hold the definitions for all prototypes like v_mesh, v_material, ... and also: public ShadowCastingMode[] ShadowCastingMode;
you can simply change it for the 2nd prototype like: ShadowCastingMode[1] = ShadowCastingMode.Off;
no refresh needed as these properties will be looked up each frame.

 

Im getting severe flickering of the grass if I have the following

Application.targetFrameRate = 60;

using compute or not doesnt make a difference

 

which version of unity? which render pipeline?

 

Standard pipeline, 2021.2.3 but IIRC also the previous version I used 2021.1.15

Now I think about it, it also happens when I press ingame menu (but Ive been ignoring it for the last few months), give me an hour I'll look into it more

edit: OK mate it looks like its the same issue, when I display the ingame menu, I also was setting Application.targetFrameRate = 60; in that function

 

ok no idea what might be going on there.

 

Hi! What could the error be related to? And how can it be fixed?

GrassManager thread crashed: System.IndexOutOfRangeException: Index was outside the bounds of the array.

The grass rendering stops after the error appears.




HDRP 10.8.1
The component is attached to a 3x3 km terrain, with 4 types of grass.
