[Released] Lux URP Essentials

Was there ever an official answer for this or anyone using these shaders on the Quest/Go? I would be interested to know as this looks perfect for a VR title I am working on.

 

I'm using the Tree creator shaders from LUX now, and I have one question:

When I apply the material with the lux shaders to a tree it works,
but when I change the Tree Seed, it goes back to the default Hidden/Nature/Tree Creator Bark Optimised shader.

Is there a way to overwrite the default unity hidden shader with the Lux shaders?

 

you have to apply the lux lwrp shaders (non optimized version) to the material used within the tree creator. then the tree creator will generate the optimized materials using the lux optimized shaders.

 

i ckecked them on the rift and dx11. gles 3.0 should be fine as well but i did not check.

 

Thanks that fixed it.
I did get 3 warnings in the console:
Don't know if they are safe to ignore?

Im testing on 2020.1a9

should be safe to ignore.

 

Hmm, I checked the demo scene, and I don't see the problem there by default, even with the clipping planes set to .3 and 30000. However if I parent everything in the scene to an empty game object, and move the gameobject to x 20000 y 20000 z 20000, then the issue shows up. Playing with the lighting didn't change it that I could see.
I realize that such a large world is an edge case, but is unfortunately necessary for the kind of game we're making.

 

sorry, this is nothing i can help with
hdrp introduced camera relative rendering which would probably fix the graphical part of this. but physix still will break afaik.
maybe dots physics or havok use double precision but standard float precision in unity does not cover such huge areas. some people say it gets unstable at 6000 m, others say you can go up to 9999. but 20000 is definitely out of scope i think.
a common way to work around this is to use a floating origin, but i am sure that you are aware of this.

 

It's cool, I think I can work around it.

I wonder if these kinds of features will eventually make their way from HDRP into URP?

Yeah that's very unfortunate, but I'm sure we'll find a way to make the phsyics work!

 

i would like to see a color overlay to the terrain mesh shaders

 

and a base normal map featuere

 

How would I go about editing the decal shaders to work with Orthographic cameras? It only seems to work with perspective cameras at the moment.

 

decals supporting orthographic projection are coming in version 1.2:

 

would be nice - but unfortunately out of the bounds of gles 2.0 as too many texture samplers would be needed.

 

@larsbertram1 Thanks! Also, is there a way to tile the texture used in the decals? I'm trying to hack my own solution into the unlit decal shader. Any thoughts?

 

version 1.2 is available!

 

the uvs are calculated in this line:

float2 texUV = opos.xz + float2(0.5, 0.5);​

which centers the uvs in objectspace. you can simply scale them afterwards like:

texUV *= 2.0f;​

or offset them:

texUV += float2(0.1f, 0.6f);​

if you need per material control over it you have to add a property to the properties block like:

_TilingOffset("Tiling (XY) Offset", Vector) = (1,1,0,0)​

and add _TilingOffset to the CBUFFER like

float4 _TilingOffset;
​

then you calculate the uvs like this:

float2 texUV = opos.xz + float2(0.5, 0.5);
textUV = texUV * _TilingOffset.xy + _TilingOffset.zw;​

 

Hi can you guys give an use case for this feature? Thanks a lot!

 

Decals:

• Use them to decorate your scene – like adding some damage, dirt or puddles here and there.
• Use them to dynamically add feature such as blood or damage.
• Use them to add some kind of a "ring of spell force"
  
• Use them to do an old style blob shadow.

Doom without and wit decals:

 

Cool example! I'm afraid I was not clear, sorry.
I was actually asking about the meaning that decals support "orthographic" projection. I had already seen decals in the samples and I was curious about this feature.
Thanks a lot!

 

orthographic decals were a customer request.

 

Perfect! Exactly what I needed. Thank you so much for all your help.

This is the result -- made some underwater caustics for my pet simulator game - Voxelotl Garden.

 

nice – but quite heavy i guess.
i wonder if it would be cheaper to add caustics right in the material shaders – where they cold even effect lighting.

 

Hello, I am interested in this package. But a bit confused about content. Does this asset also contains the assets " Lux Water" and "Lux Particle Effects" ? Or this one is LWRP compatible version alternative of those assets ?

 

it contains the LWRP version of Lux Lit particles and a simple LWRP water shader.
Lux Water does not work with LWRP.

 

First tests using vector displacement fields to dynamically bend grass.
no additional camera is used

 

I think I understand what you're saying. Add Caustics to the LWRP shaders used by the environment and characters instead of projecting a decal over the whole environment.

I'll see what I can do to make that happen. I'm trying my best to learn shaders, so it is a bit of a struggle.

 

Hello, I recently purchased your asset and I'm looking forward to implementing but I'm running into a small issue, well its more of my own ignorance than an issue; What is or how do I get a skin mask for "Skin Lighting", I don't see how to export that texture map in any program including marmoset which has every texture type. thanks for any help

 

take a look at the top down projection (rock) shader e.g. the most complicated part is about the projected normals – which you can simply skip as you do not need it.

 

oh, that is my own invention it is like a metalness mask: all parts of the mesh which shall receive standard pbr lighting instead of skin are simply black in this map.
think of a bare arm with some metal parts on it (like jewelry or armor): usually you would have to use 2 materials to get proper lighting on skin and armor. but using the skin mask you can simply use the skin shader on the entire arm.
got it?

 

@larsbertram1 Ha Thanks, that explains a lot! while I have you, are you using any assets that allow you to plug in the different maps on channels within unity or just using photoshop? I am familiar with photoshop just trying to see the best workflow

 

using photoshop.
and usually a bunch of adjustment layers.
using a unity editor extension would probably mean – 2 clicks?
1. doing the changes in photoshop.
2. finding your combined texture asset in unity and recreate it...

 

Thank you very much

 

Does Lux for LWRP support WebGl, I'm having a weird issue when viewing in webgl, doesn't seem to work correctly, shader turns off.

Thank you.

 

i never really checked this as i expected LWRP to just support all platforms. but i gave it a try and it looks fine.
i checked the "custom shader graph demo" scene which looks like this:



so my answer is: yes.

 

Ok, thank you! That narrows it down on my end.

 

Some parameters of the "Lux LWRP Lit Extended" are not refreshed when modified, and "Advanced Option" parameters did not work properly when modified at run time. But the “Lightweight Render Pipeline/Lit” is correct.

unity 2019.2.11

 

which are not refreshed?

sorry, but i doubt this.
advanced -> specular highlights and environment reflections bot are defines as shader features:
#pragma shader_feature _SPECULARHIGHLIGHTS_OFF
#pragma shader_feature _ENVIRONMENTREFLECTIONS_OFF
so they get evaluated only at compile time and can not be changed at run time.

 

Lux LWRP Essentials version 1.21 is available.

 

Hi, I recently tested the Shaders in VR in Unity 2019.3.b8 and URP 7.12. It seems the new URP post processing only works in (Single Pass Instanced) mode, in Single Pass mode it breaks. The main problem is that many features of the LWRP Essentials like decals, etc. seem only to work in (Single Pass).

 

i haven't checked urp and vr yet. but read some posts which claim that vr seems to have a lot of problems with urp in general when it comes to read the color or depth buffer...

 

just a suggestion,

maybe a skyshader that supports a tilling cloudtexture moving across the procedural sky? i made my own in shadergraph but its not looking very good

 

i checked single pass instancing in urp and tweaked the water and decal shaders accordingly.
i will send you a package via pm so you may give it a try. feedback is welcome

 

version 1.22 has been published.
### changed:
- Hair shader: Cull exposed
- URP: Experimental support for "single pass instanced" rendering added to the decal, water and glass shader.
- PLEASE NOTE: Shader graph shaders do not support VR using URP at all... they are broken.
### Added: - Hair shader: VFACE added which provides proper lighting on back faces.

 

latest update lets you turn on VFACE which allows to have proper back face lighting (including ambient reflections).

 

not all the shaders are working.

is there support for toon environments in this package ?

 

which version of unity do you use? 2019.3b?
it looks as if the materials lost the connection to the shaders...
fortunately the materials more or less contain the name of the shader which must be used – so it is pretty simple to reassign the shaders.
i will update the urp package.

it comes with a versatile toon lighting node for shader graph as well as flat shading.
are you looking for anything specific?

 

Im looking to synchronize the terrain with my characters (more than it is in this pic)
im on 2019.2.3

 

hmm, difficult to say wahr kind of lighting your characters use... any info about this?

 

they are using the "real toon" shader from the asset store
other wise I do not know enough to go into detail

unfortunately the toon shaders in the demo seen are some of the ones not rendering
