[Released] Lux URP Essentials

yeah! they are use different features.
this below is the "stupid" decal's shader in frame debug:


And this below is decal lit:


the different feature is _NORMALMAP_

 

YEAH! the problem is mormal map. when i enable the normal map on other decal,they become black.
when I turn off the normal map on "stupid" decal ,it got colors.

 

Even I enable the mask, it still correct(or not correct but better). emm, without normal map.

 

there is already.

 

hmm, it looks as if i have forgotten to wrap the unpack-macro.

so you can try to edit the shader and find:
half3 normalTS = UnpackNormalScale( SAMPLE_TEXTURE2D(_BumpMap, sampler_BumpMap, texUV), _BumpScale);
and replace it with:
#if BUMP_SCALE_NOT_SUPPORTED
half3 normalTS = UnpackNormal( SAMPLE_TEXTURE2D(_BumpMap, sampler_BumpMap, texUV);
#else
half3 normalTS = UnpackNormalScale( SAMPLE_TEXTURE2D(_BumpMap, sampler_BumpMap, texUV), _BumpScale);
#endif

this should fix the normal issue. maybe it also solves the other issues...

 

yes, mobile not support normal scale. and you forgot.

 

Thank you.

 

and with this warning in shader:
Use of UNITY_MATRIX_MV is detected. To transform a vertex into view space, consider using UnityObjectToViewPos for better performance.

 

you may ignore the warning.

 

After modify the shader like this below:

Code (CSharp):

1.  
2.                 half3 normalTS = 0.0f;
3. #if BUMP_SCALE_NOT_SUPPORTED
4.                     normalTS = UnpackNormal(SAMPLE_TEXTURE2D(_BumpMap, sampler_BumpMap, texUV));
5. #else
6.                     normalTS = UnpackNormalScale(SAMPLE_TEXTURE2D(_BumpMap, sampler_BumpMap, texUV), _BumpScale);
7. #endif
8.  

I still get dark decall like before. even I comment the UnpackNormalScale code.

 

have you checked the texture import settings of the normal?
apart from this lwrp for 2019.2 has a lot of bugs. so it might be a good idea to downgrade to 2019.1 or upgrade to 2019.3.

 

I already checked. I will test in 2019.3

 

I tested on 2019.3 with ogles 3 and vulkan. same result.

 

damn. of course you would have to adjust the normal mapping here as well.
but if "sample normal" is unchecked you should get at least some basic lighting.

 

yes,uncheck the normal,will get some basic lighting , but I must move on to other work. I'm counting on you.

 

Hey. I'm trying to make a skin shader with transparency to hide body parts that are under clothing, using a texture stencil.But when I use alpha the object doesn't self shadow and it newer goes completely opaque.
Is there a way to do this using the shader graph?

 

transparents do not cast shadows.
you should use alpha testing instead of alpha blending.

 

@osss what was the problem?
"grass displacement doesn't work in 2019.3f3"

 

it works fine

 

fine

 

turned out to be a precision problem and actually mobile needs the normalize i commented.
so it should be (around line 345):
inputData.normalWS = normalize( cross( ddy(wpos), ddx(wpos) ) );

 

Yes! You made it!!! It's work on my devices.

 

simple volumetrics are coming:

 

it will work with vr?

 

yes

 

version 1.31 is available

### Fixed:
- Decal, Terrain shader: UnpackNormalScale wrapped properly (mobile).
- Decal Lit shader: Normals fixed for mobile (caused by half precision).

### Added:
- Decal Lit shader: Fade between scene geometry's normal and projected decal normal.
- Volumetric shaders added: Light beam, box and sphere volume.

### Changed:
- URP: Changed to version 7.1.6

 

Thank you for the new update and new feature.
I have question. Could you make tiling patterns shader ?
Something prevent the repeat patterns on terrain.

 

there is already a shader graph node which implements this: procedural stochastic sampling.

 

OK. I will try that.
Thank you.

Update:
After I tried it...Please make your own shader. I think you can make more better and simple than this one.
After I followed setup steps, the shaderGraph in my project crashed and I could not fix it. Thanks God that I back-up before. I don't know what you working at but put this in your list please.
Thank you.

 

When will there be support for the URP? I just downloaded the latest version and none of the shaders are working. They are all pink. Trying to covert them results in error messages.

 

you have to import the urp package.

 

Thanks!

 

## Version 1.32 is available:

### Changed:
- Lux LWRP Extended Lit Parallax shader: renamed to Uber

### Added:
- Lux LWRP Extended Lit Uber shader:
- - Support for bent normals added.
- - Horizon Occlusion added.
- - Geometric Specular Anti Aliasing added.
- - GI to AO added.

 

and here is an overview of the improvements regarding specular lighting such as geometric specular anti aliasing, simple bent normals, horizon occlusion and GI to specular ambient occlusion:

 

looking into a heavily zelda inspired scene setup i added some tweaks to the shaders like stabilizing the rim light effect and introducing a shadow bias to the toon effect.

 

Couple questions.
Has anyone using this you know of had success rendering decent size outdoor nature type scenes in oculus quest using unity 2019?
Also can the terrain or mesh terrain shader use a global colormap with the 4 texture splatmap to increase the look desired on the terrains?

Really wanting this to work for quest so I can create some decent size nature scenes. I know there's limitations but if this can do a great job the rest is all trickery like most things in large scale 3d environment worlds.

 

@larsbertram1 , is it possible to do real-time tinting for terrain textures with the terrain shader?

 

i think so. why not?
either use material properties or global colors and change them using script.

 

@larsbertram1

hello,
can you provide speedtree 7 URP shader with Environment Redlections and receive shadows option?
thanks.

 

Version 1.33 is available
### Added:
- Toon Lighting: Directional and additional shadow bias added which lets you control the shadow strength and create Zelda like lighting.
### Changed:
- Toon Lighting: Stabilized rim lighting.

 

i haven't used any speed tree for months. and 7 is a bit outdated. so maybe but no eta.

 

will u be renaming the pack to "lux URP essentials"
since what ive heard LWRP will not be supported in later releases(or am i wrong?) so only URP

 

some day, yes.

 

Hi. I have Lux LWRP Essentials that I'm using with Unity 2019.2.15f1. I am using the Tree Creator Leaves and Tree Creator Bark(std and optimized) shaders on my trees, which work perfectly, but I need to adjust the transparency in-game and due to my total lack of knowledge of shader development I cannot figure out how to achieve this with these shaders. I have fader code that works with standard shaders I used before switching to LWRP and now I want to modify that to work in LWRP with your shaders. Thanks.

 

i guess you are talking about something like fading out a tree if the camera gets close.
well, that is a bit tricky – especially on the bark because this shader regularly is an opaque shader. fading it out would need you to make it use alpha testing first.
but alpha tested shaders are more expensive than opaque shades because you will loose early depth testing on the gpu. so if your trees where single game objects you could swap prefabs if the camera was near.
if you placed your trees using the terrain engine... you will have to pay the price for all trees at all distances.

so first of all: how does your scene look?

 

Hi, thanks for the fast reply. Your assumption about fading the tree when it is between the camera(3rd person) and player is correct. All trees are dynamically generated from prefabs so they are individual game objects so swapping is an option...maybe. I tried just turning off the material when the player is blocked, which worked well, but then the player can run into the tree when it's invisible because there's nothing to see, which is not acceptable. Would drawing an outline around the bark and leaves be possible and be a performant way to solve this issue. This may be acceptable in game play though I'd have to try it. FYI, I also tried using the Lit shader on the bark but when varying transparency it is never fully opaque. It seems to stay at about 50% transparency even when alpha is 1.

 

it would needed 2 materials (stencil write + outline). but the provided outline shader does not support any vertex animation like the tree creator shaders do.

no idea regarding this. but you do not really want to use a transparent shader: this would give you some kind of x-ray style on the trunk as faces in the background would not be occluded properly.
the way to go i think is alpha testing and stippling out the trunk.

upcoming version 1.34 will add this feature to the Lux Uber shader. so you may look it up there and add it to a copy of the leaf and bark shader. then simply swap out the tree prefabs with a prefab which uses the camera fade enabled shaders when the player gets closed.
actually the leaf shader already uses alpha testing. so it will not suffer much from enabling camera fading (just some more math) while the bark shader originally is an opaque shader. you may do some performance tests only using the camera fade variant: if the trunks do not cover a lot of screen space it might not be worth swapping the prefabs.


Lux Uber – Camera fade
Geometry gets stippled out while the camera approaches. Shadows may stipple out as well although this looks pretty odd in case you do not use 4 cascades and a rather high res shadow map.
The fade value is calculated per pixel so details further away are still opaque.

 

Thanks for all the feedback. I will wait for the next update and try that out. You'll likely hear from me again as I try to implement it.

 

Howdy, two things, first that alpha tested outline shader doesn't seem to do anything with the texture input and it doesn't render anything if the alpha cutoff isn't zero. Dunno if I'm just using that wrong or what.

More importantly though, I copied the settings in the demo for the outlined spheres and applied them to my character but no matter how I fiddle with the settings, the texture is super bright and it's hard to make out the details on it:



I'm on unity 2019.2.16 and I've tried disabling all the lighting too.

Any ideas as to how to fix this would be much appreciated!

 

hmm, i can not reproduce this.
i checked it in 2019.1.3.f1 as 2019.2. was too buggy last time a had a look into it.

left sphere: bulit in lit, right sphere: lux lit extended.
i can not spot any difference... (color space: linear, built target: pc)

the shader works perfectly for me:
here it uses the texture "T DryGrass AA". maybe the alpha channel of your texture is incorrect?
