[NEW PATCH] uNature - GPU, Interactable Grass. Interactable Trees, MultiThreading and more!

Hi Elroy,
Has there been a fix released for this first detail showing problem?

 

Hey sorry out of town till tuesday but got it 95% done. When I am back I will finish it up

 

No problem. Look forward to it.

 

Hi, just bought your Asset. And weird things happen.

1) When use copy foliage from selected terrain, density of grass changed if compare with original terrain grass contribution
2) Grass is spawned on houses
3) Grass don't showen in play mode

Video:

Any help or suggestions please.

 

Hey out of town so can't give a fully detailed response but will try my best.

1) Ok so resolution changes doesnt work yet in that version so what you can do is in the prototypes adjust max generation density to max (in the foliage manager window) if doesn't look good enough wait for the Remastered version on which you can control resolutions

2) on the foliage manager there should be "Maps Generation Mask" remove default (click no on the dialog) then put your terrain layer and click Yes on the dialog.

3) Add UNSeeker to your camera

 

Thanks for the answer. I needed to read the manual before writing to the forum

Another strange problem, which seems to be not in the manual.

If check grass to receive shadows, strange artifacts appear throughout the whole scene. Examples in the image:





I tried to rebake light, but it did not affect anything
My light setup:

 

Interesting will have a look when I am back!

 

Are the shadows losing resolution due to so many new items being added?

 

Could be! I am making my own light weight shadow simulation for Remastered hopefully will share results this month

 

Switching shadow projection from "close fit" to "stable fit" in "quality settings" fixes shadow problems.

 

Oh ok good to hear!

 

Is UNature broken in 2017.3 ? Im unable to paint anything since upgrading.
(even in fresh projects with newly downloaded and imported unature)

 

Hope not... was about to upgrade.

 

Was already reported, on it!

 

Good to know! Thanks

 

Hey!
Just tested seems to work well... Are you using the store version?
Also, did you make sure that the heights are correct? (Terrain included in the generation mask in the foliage manager window)


Elroy

 

I just bought it and started playing around with it in my project. Looking at FoliageGrassMap.GetChannel, it looks like you can only have a maximum of two different types of grass on the same tile, is that correct? Are there any plans to change that?

 

Yes and yes, thats a temporary solution to conserve memory, remastered version already fixes it. Once all done I will fix it on the asset store version too

 

What's the time frame on the new version?

 

Currently its functional but not production ready. I have a few features I want to finish and then push the beta out.

I don't have an ETA at the moment but I will get a fix for the 2 prototypes per cell really soon!

 

Right thanks

 

Yeah, using the store version. 2.3 i believe it is. Im currently re-installing and updating unity to the latest patch. will see if that fixes it

 

Ok awesome! Keep me updated! if still doesn't work send me the project privately (a small project with the problem, not your whole project ) and I will see what's the problem

 

Okey, managed to get it working again i think, by turning of "Use Instancing" this has always been on before. I will test some and see if everything works okey

Edit: Okey, things doesnt seem right. The grass flickers on and off as i move the camera, and i get Array index out of range errors when painting. il look around some more and then send you a project

 

K cool, using the latest version?

 

Latest store version and latest Unity

 

hi
the description says "touch bending coming soon"... when would that be added?

 

K, send me the project privately and I will fix it

It has been included since the initial version. Maybe a typo on my end. I will check

 

do you have a demo windows executable using 2.3? the performance on the current package is pretty bad and it seems you have improved it a lot since that version (no clue what version was that .exe built on)

 

The demo I think was built on the initial version. Don't have a new one yet but will create a new one with the upcoming bug fixes update (Which is really close, decided to wait for @Fabbs so his bug will also be in the patch.)

 

ok, can you also post here the fps gain from that version to the newer one? i'm sure most will be curious to compare

 

Regarding memory changes, which is the biggest change point, it is described here:

Regarding performance, I do not actually recall. I will have to make some tests when I submit the new update. Will keep you updated.

 

@ElroyUnity

Edit: The issue with the SpeedTree shadow flickering when using uNature was due to the Shadow Projection setting having been set to "Close Fit". "Stable Fit" is the default. Reverting back to the default fixed it. Absolute wildcard issue considering it never appeared until using uNature, but now you know.

Just ran into the exact same issue. No grass unless instancing is turned off, which (with Vsync disabled) dropped FPS from 1600-1700 down to 400-500, no doubt from grass no longer being instanced. Is a fix for this issue in 2017.3 coming soon?

 

Thats a big bug. Thanks for letting me know! Will work on a fix and submit!

 

Working on the fix! Fixing it asap

 

So guys not really sure why its not working with GPU instancing. Been trying to fix it but seems like there's nothing wrong. I will try to message Unity about that. Meanwhile all I can really say is to disable the GPU instancing on the foliage prototype settings

 

That's a shame. Will be sticking with 2017.2 then, as instancing is mandatory for performance. How close are you to a fix for only being able to use 2 prototypes per chunk?

 

That one will take a bit longer but its coming

 

Any update?

 

Hey - almost done with the update but on vacation now till Monday, didnt make it. Will hopefully push the update on Monday or Tuesday

 

Hi Elroy,

Might I ask you how to fix this visibility issue? P.S. this is test project, where I reworked your asset to work on my project as I use 1024 resolution and wanted one HM... it all works. Just I am lost as all grass seems to be attached to any grid. I am in a Base.Cginc and nothing helps (like changing anything around noise)... Any idea what should work?

P.S. it looks well when you have 1-2m size grass but i use around 0.35m grass in my project and when using smaller size, grid becomes such visible...

Thanks

 

I don't think I understand :/ can you re explain the problem?

 

I mean that you can see grass in the lines, without any randomness. If i play with noise, it does not affect it any such way to reduce this effect. I would like to make to grass spawn +-(5-10)cm in x and z axis from positions which are precalculated. to make it more natural.

This should be affected by Noise but strangely it is not...

 

That might be because the cells are too small. Increase the width of the grass

 

Unfortunately cannot increase the width as normal grass does not have 2 meters and we have to make it fit to the scale. Any idea what to pass to shader to better displace it? I will try to override density, this could help. But still I will be thinking how to make it more spread randomly...

 

Will be back home on monday and help you solve it on screen share

 

Did you hear back from them? I ended up doing a heavily customised rewrite using your basic concept, but less generic and more suited to my project. I had it all working in 2017.1, it was great. Now I've just tried to upgrade to 2017.3 and it's not working. I think it's because the calls to tex2Dlod in the vertex shader aren't working. (I'm also using instancing). Is this the same problem you were having?

 

I am not sure really, seems like the drawmeshinstanced is just bugged, I have a patch coming up on Monday - Wednesday. After that one I will open a bug report and get an actual repro project for unity.

 

Ah I see everyone does heavy customizations I also had to make it work on my 1024px terrain just with one texture, which is sent by my code and is same for terrain shader. I am working on billboarding. And better grass mapa (currently using 4 prototypes densities per 1 map - but I will separate it to 8 prototypes per map as it uses just 4 bits) still thinking more about atlasing prototypes per density map and so reducing amount of chunks (4x or 8x)... Btw, do you anyone have some improved grass shader? I do not like much surface shaders, I am more into fragment ones...


@Elroy great, when circa we can make shared screen call?

 

Well I can confirm mine works when I don't use DrawMeshInstanced. Let us know how the bug report goes

I am doing something quite similar actually, 1024 square terrain with 8 grass prototype densities in one texture. I'm using a standard surface shader but with some extras for snow and dryness.
