shaders

[vocal wadi]

The shaders I want to make at the moment are geometry shaders though, which seems hard

[lucid cedar]

Oh, that's difficult but not impossible. For kicks, start out with a geometry shader that duplicates every tri.

Once you have the shader basics down that is

[vocal wadi]

All example I can find just edit geometry. I want to generate it from nothing. That's doable right?

[past pewter]

https://jayjingyuliu.wordpress.com/2018/01/24/unity3d-intro-to-geometry-shader/

also you can't start from 'nothing' a geometry shader needs a trianglestream to work with

[last token]

can u use those for heightmaps

[vocal wadi]

Aww, alright, guess I will modify cubes then. Thanks for the link

[last token]

u would essentially make new separate triangles above it

in direction of normal

[near flax]

yeah you can use that for heightmapping

[last token]

wait can u set max verts without constants

[near flax]

although i think it'd be more efficient to just displace verts for that instead of generating new geometry

[last token]

so u mean like a fragment shader?

[near flax]

iirc just constants

no like move vertices in your vertex shader

[last token]

o

but thats vertices

not like

full displacement

[near flax]

what do you mean

[last token]

if u have a single plane

and u put a heightmap on it

it should emboss or engrave ur plane

not just verts

like it does in blender

[near flax]

there are other techniques you can use for heightmapping, but they can also be less performant

kind of depends on the situation

here's one that just does vertex displacement on unity terrain

[last token]

ye but thats bc it has a lot of verts

[near flax]

yes

[last token]

purpse of heightmap is usually 2 increase detail with less physical polygons

[near flax]

the geometry shader would have the same issue, but you're adding more vertices

for that purpose, i think tessellation would probably more appropriate tbh, but i don't know how the performance would compare

[last token]

oh nvm thats not how it works in blender

in blender it is the same thing as normal map except it can displace verts also

https://i.gyazo.com/4dcb767b3ff91173254428d27893bb40

i didnt use a lot of verts so it looks ugly

[lucid cedar]

If you wanna generate geometry from "nothing", you can technically do that with just a single triangle mesh. @vocal wadi

That will make the shader run once

You can even choose to completely ignore the original triangle's vertex positions

[last token]

ye

u put multiple into stream

[vocal wadi]

Can't get the online example to work. Adding "#pragma geometry geom" breaks it (gives unexpected '}' just before the fallback declaration, makes the declaration unsupported, and complains about a missing vertex or fragment program)
If I keep theo hter pragma, it complains that it has both #pragma surface as well as another kind

[past pewter]

you can't use a surface shader template

[last token]

exactly

[vocal wadi]

Thanks, I found another template on shaderslab

[last token]

u can only use surface in its own pass

otherwise u gotta use fragment

so u can use geometry and stuff

[vocal wadi]

Ah, I see! I haven't really learned the basics yet. I'm not patient enough

[last token]

just make it simple shading like diffuse * (dot(normal,surf)*-0.5+0.5) * atten

[past pewter]

you could have used an unlit template in unity

you're skipping a lot of learning

[last token]

^^^^^

y would u learn about geometric shaders and etc

w/o first learning about surface and fragment shaders, shadow casting etc

[vocal wadi]

I want to make a spinning tesseract

[last token]

https://docs.unity3d.com/Manual/SL-VertexFragmentShaderExamples.html

[past pewter]

how do you plan on doing that?

[last token]

u cant make those without knowing any of this first

cuz u are morphing the shape of the object

a surface shader wouldnt work in this case

unless u had like a vertex thing on the forward pass

[vocal wadi]

I've read a few pages about making shaders, but none said what surface actually meant
I was hoping I could just create everything mathematically (making points and doing some linear algebra with them shouldn't be too hard)

[last token]

surface shaders are a part of the forward pass (ftmp)

and ur not rlly making points unless ur creating new geometry with the geometry shader

otherwise u would be morphing original geometry

[past pewter]

@vocal wadi but if you have a set of points, what do you plan on doing with that?

[last token]

i mean u could have a bunch of if statements and be like

'if coordinate > this move it here'

but thats like def not how u should do it

[vocal wadi]

Can't EmitVertex(); connect them?

[last token]

what

easiest way 2 do this would actually b 2 use a geometry shader and generate the shape manually

also means u have 2 do manual shadows and lighting

cuz if u generate it using shader instead of using existing points it easier 2 actually move the shape

[past pewter]

@vocal wadi you would have to figure out where all the tri corners of a tri strip should go for every box

[vocal wadi]

I don't need fancy colors or anything. And maybe it's just difficult to do 4D stuff. It's not like I can make it in Blender

[last token]

its not really that hard

[past pewter]

4D with meshes? not gonna work

[last token]

yea u cant make a 4D mesh but

the animation of that 4D box thing would be pretty simple using trigonometry

and for best results u can use a single triangle mesh

otherwise ye good luck trying 2 find each individual side and offset from existing verts

[past pewter]

you both are going way too fast and confusing things

please try easier examples first

[last token]

ye

[past pewter]

try making a shader that draws a tesseract using line primitives first

before you start turning it into tris

[last token]

i need 2 figure out the shadow stuff firs tho

i understood most parts of making a shader however

idk what its doing for shadows

[past pewter]

it's impossible to use surface shaders and geometry at the same time so shadows and lighting are not something to consider at all at this point

the forward rendering pipeline ignores the geometry stage (!!!)

[vocal wadi]

Don't you need triangles though? Lines are infinitely thin, I don't think I'd be able to see if it works

[past pewter]

I'm not sure what you mean, you said you wanted to generate tesseract points and draw them

having simple lines show and connect those points is a good start

you'll learn about projection and transforms needed

[vocal wadi]

You can't draw a line, there's nothing to render since it's 2D (in my mind, anyways)

[past pewter]

you can either draw points, lines or tris, you'll see all of them

a line is not 2D

[last token]

yea but if draw line will be reaaally thin

[past pewter]

did you ever try?

[last token]

me?

[past pewter]

how can you say all these things and never tried any of them?

[last token]

?

[vocal wadi]

Nevermind, a line is 1D. If it's visible then I'll admit I don't know how it's rendered

[last token]

no

a line is a connection between 2 points

a polygon is a connection of 3 or more points

[steep swift]

Can't you just build all the geometry in advance into vertex.xyz color.r for example

And then you only need a vertex shader

[last token]

u can perfectly fine have a 1D, 2D, 3D, 4D+ line

well yea but ur gonna have 2 figure out where everything is and where it goes

[vocal wadi]

In that sense you're right

[last token]

probably easier 2 just generate the geometry on the fly

[vocal wadi]

Man shadertoy is bricked

[last token]

idrk

[steep swift]

Unity supports rendering lines. Don't know how to control the thickness

[last token]

wym shadertoy

[past pewter]

you can specify a width, how is it not wide enough?

yes you can

[last token]

yea u can draw lines

[vocal wadi]

A program to convert shadertoy shaders into Unity ones. It's generating shit like "blackbi.uvragColordy(i.uvli.uvragColorat Temp);"

[last token]

but they will not be like drawign a box

ew thats bad

write it in unity or use amplify or something

[past pewter]

@last token please stop telling people what to do without ever having done it yourself

it's wrong

[last token]

no im saying

if u draw a line

[steep swift]

I'm confused. If You want a tesseract why do you need to raymarch it? Isn't it easy to rasterize a projected tesseract

[last token]

it wouldnt look like drawing a rectangular prism

[past pewter]

this conversation is making my head spin

[last token]

it would look like wireframe

[steep swift]

That's what drawing lines does yes

[past pewter]

please learn the basics before helping people

[last token]

i know basics shut up

[past pewter]

be civil with me please

[last token]

i am but u wont stop complaining

[past pewter]

you keep explaining things that are not true

[last token]

like what

[past pewter]

it's not helping anyone

[last token]

like what

[past pewter]

like lines being invisble and doing shadows in geometry shaders

[last token]

i didnt say theyre invisible

[past pewter]

yea but if draw line will be reaaally thin

you can specify the thickness

[last token]

ye

[past pewter]

stop just blurting out random things

[last token]

but it will be thin line and not a box

u can make the whole thing wireframe / only use lines sure

but it not look the same as a shaded one that uses actual geometry

[past pewter]

forget about doing that for now

[steep swift]

I think this is just a simple misunderstanding-> everyone has a different idea of what the question author wants

[past pewter]

I was trying to take it step by step

[last token]

also is this wat they mean https://media2.giphy.com/media/AK986lrhNHiZq/giphy.gif

[past pewter]

dude, I know what a tesseract is

and how to render exactly that in vrchat

[last token]

i dont care i didnt say 'this is what they mean'

[steep swift]

I shouldn't have butted in but I wanted to point out that it is possible to pre-generate geometry and then you only need a vertex shader to render a 3d projection of the tesseract

[last token]

wouldnt u also need a color to specify the 4th dimensional coordinate or something

[steep swift]

Yes

[last token]

wait unity has vertex colors right

[steep swift]

Yes or you can use uv

[last token]

kool

wait

how many points would u need

[steep swift]

However it gets a bit complicated when you want nice thick (prism or cylinder) lines because you might distort those if you build them in 4d geometry. Using a lines might be an easy way to start out like 1001 was suggesting (though he was going after the raymarch approach which could work too nevermind)

[last token]

yea but wont raymarch one be less performant

[steep swift]

If it's simple lines I think it's just 16 vertices

[past pewter]

I didn't even mention raymarching, and I won't because caffeine was trying to learn geometry shaders

[last token]

also they probably nt make their own raymarcher..?

[steep swift]

Oh good sorry I was trying to figure out amidst all the noise

[past pewter]

yeah I was trying to reduce the noise

but it's no use trying to take it slow

going back to lurking and not helping anyone, peace

[vocal wadi]

I appreciate the comments by the way! I figured out that I could modify another vertex shader and then modify the vertex points and such. It's not a tesseract, but it still looks cool

[last token]

u definitely learned ..

[past pewter]

np, I hope it helps a little @vocal wadi

[vocal wadi]

It did, thanks! And at the very least I learned that shaders are difficult. I can make fun objects for now, but nothing actually useful (like a fur shader)

[past pewter]

you can look how xiexe's fur shader works, it's very cool https://xiexe.booth.pm/items/1084711

[last token]

it a lot more complex tho isnt it than the typical shader

cuz it was optimized quite a bit according to xiexe

[steep swift]

No it's quite simple and well written

[stiff berry]

http://hhoppe.com/fur.pdf

if you are curious about the technique

[steep swift]

I mean it also has a geometry shader so the lighting model is simplified into a vertex fragment approach compared to the feature support in XSToon

Optimized doesn't mean complex

[last token]

o ok then

yea but sometimes people can optimize stuff to the point where a lot of information is lost

i.e. sum of range of numbers from using a for loop to using a formula

[steep swift]

I'm sure compromises were taken to keep it simple while being as fast as possible

[silk gorge]

gotta have that perf

[stiff berry]

@past pewter by "forward rendering pipeline ignores the geometry stage " do you mean shadows won't follow the newly generated geometry?

Can't you just copy the geometry pass to the shadowcaster pass and it will actually show the correct shadows?

or is something else in the pipeline the problem?

[faint fulcrum]

Nope, can render shadows fine by doing so, working on one geom shader myself atm to replicate the "living particles" of extruded geometry floor

Geometry shaders can be used to both generate and discard vertices (cant discard in vertex stage), but theres an upper limit of how much you can generate. Tesselation was designed for doing the finer geometry control and subdivision (so you dont have to pump high resolution meshes for heightmapping)

[stiff berry]

in my limited experience(just a grass shader) generating using high vertex counts with tessellation was slower than using a high vertex count mesh without a tessellation stage

[last token]

the limit is set by the shader but theres also like a memory based limit right

[stiff berry]

may or may not apply to other things

[last token]

well yea isnt it supposed to be

ur generating them on the fly as opposed to using existing ones

[faint fulcrum]

Most likely yeah, it is quite heavy

[last token]

honestly tessellation shader only good for like super up close detail

cuz otherwise using LOD would be better bet

[steep swift]

@stiff berry i read that comment as referring to surface shaders being incompatible with geometry shaders, but that's due to a technical unity complier limitation not a general issue with forward rendering afaik

As long as you implements the correct geometry in a shadowcaster pass as well I don't see the issue

[past pewter]

try it 😉

[halcyon kestrel]

Tessellation is slow because it requires two extra stages in the shader. Surface shaders with geometry stages dont work because unitys macros are finnicky and not scalable. You have to do some stupid things to get them to work with geometry stages for lighting and shadows.

So it's a unity compiler issue. Not a forward rendering issue.

[past pewter]

kejiro's take on this https://github.com/keijiro/StandardGeometryShader

[steep swift]

// This shader only implements the deferred rendering pass (GBuffer
// construction) and the shadow caster pass, so that it doesn't
// support forward rendering.

[halcyon kestrel]

Kejiro does everything in deferred.

[steep swift]

Never seen how deferred works but it outputs SV_Target0-3 for each type of lighting

Does that work in VR

[halcyon kestrel]

I mean....

It works...

It's not pretty

But it works.

No AA good enough for deferred VR

TAA is kind of close but things get jittery

You can actually try out TAA in vrchat using post v2, you'll see how bad it is.

[steep swift]

But the whole game has to be set to deferred? Or can you run this in vrchat

[halcyon kestrel]

You can't run it in VRC unless unity has a similar fallback system for deferred to forward

If you have a forward rendered shader it'll be render using forward while the deferred stuff is rendered using deferred.

[faint fulcrum]

Yup, added forward compatibility to this one today and using as base

[halcyon kestrel]

For instance, XSToon just renders with forward shading even if you swap to deferred.

Vrchat forces forward rendering if you set it to deferred on your reference camera for your world.

[steep swift]

Oh interesting. Do you have an example of how you would add forward to keijiro's geometry shader without redoing all of what standard shader does

[halcyon kestrel]

Let me take a look at it

Macros

Lots of macros

[steep swift]

Haha

[halcyon kestrel]

No but really

If you look at cat-like codings tutorials

He goes over standard lighting and you could implement that here

You'll have to fuss with a few macros, namely stuff to do with shadow coordinates, but it's fairly straightforward.

[faint fulcrum]

This one specifically https://catlikecoding.com/unity/tutorials/rendering/part-13/

[halcyon kestrel]

Also, XST2.0 will have support for all of the standard lighting features, and it has a geometry stage in a variant for outlines. So you can take that from me if you want, once I release it.

[steep swift]

😃 I really need yo go through catlike's tutorials. This explains exactly what deferred does vs forward

[halcyon kestrel]

I can tell you from experience though, the UNITY_TRANSFER_SHADOW macro requires very specific naming.

o.pos is required for clip pos, otherwise you'll get an error. That one was annoying to figure out.

Unity: "Default shaders have o.vertex, but let's make our macros need o.pos!"

[faint fulcrum]

Mad props to that guy, explains stuff so well including the little to none documented built-in functions/macros

[steep swift]

Yeah I'm familiar with the shadow macro because I've had to abuse that in geom shaders. Usually filling in a struct named v with a vertex and maybe normal member

Well I always look at the source in UnityCG or HLSLSupport or UnityShaderVariables etc . Pretty much a must as unity's docs are gone or misleading

[strange crown]

Does anyone here know how to use SSR in VRChat? Iv'e seen it done in game, but whenever I try to do it myself through the post processing stack it doesn't show up in game.

[past pewter]

Can someone help me out with Model crap cuz I can't use a DAE File in Blender and its making me mad

[strange crown]

You gotta ask that in #3d-modeling

[past pewter]

already did

[stiff berry]

you need to write or acquire your own SSR shader designed to work in forward rendering

it's only going to work on objects with that shader though

no one is going to write a forward SSR shader outside of VRC though

[strange crown]

@stiff berry Do you know someone who has made one already? Or do you also have commission for this sort of thing?

I'm not sure how hard it would be to create, I never dabbled in code.

[stiff berry]

@pine ibex

[strange crown]

I already asked him, but i was under the assumption that it wasn't public use.

If it is i will be fine with paying though.

[stiff berry]

it probably isn't idk

[rancid stirrup]

I use plasma shaders for my Ash-Greninja avatars

[faint fulcrum]

@high osprey @steep swift And whoever else uses camera depth for their shaders - method that works in mirrors.
https://github.com/lukis101/VRCUnityStuffs/blob/master/Shaders/DJL/Overlays/WorldPosOblique.shader

[last token]

are texture colors stored as integers or are they floating point values

[lucid cedar]

In shaders, it's floats @last token

0-255 gets turned into 0-1

I think textures are float4's

[last token]

ooo thats nice

means i can store stuff like coordinates in them

[lucid cedar]

Yes, you can store arbitrary data in textures beforehand and read it out in the shader

It's pretty cool

[steep swift]

Using rgba half textures you can store half precision floats (hdr)

[faint fulcrum]

Yes, but beware of resolution. Also couldnt get multi-channel packing to work...

[steep swift]

Or just encode numbers as 4 fixed 8bit values

It's a good way to index extra data either by SV_VertexID or SV_PrimitiveID

[faint fulcrum]

Tired wave propagation on 8bits - na-uhh, couldnt get packing to work so resorted rto RGHalf

[steep swift]

I'm super skeptical of your 0.21582022 like what

[faint fulcrum]

Exactly, even can link ya a world with this working

[steep swift]

I mean it works for you but is it driver dependent? Unity dependent? Hardware specific?

[faint fulcrum]

Barely tested but i dont like it either

[steep swift]

Sure I can try on my win7 machine with old nvidia drivers and 9 series gtx

[faint fulcrum]

With depth unavailable, in 5.6 unity getting 0s, and in 2018.1.6f1 (Beat saber version) getting ~0.5019606
I suspect a current unity nuance 😂

[past pewter]

@faint fulcrum you know how to force a depth texture right?

_CameraDepthTexture is enabled only if world has at least one light with shadows enabled (or a unity script sets Camera.main.depthTextureMode = DepthTextureMode.Depth)

so adding a directional light with minimal shadow settings to your avatar forces any vrchat world to enable the depth buffer\

[lucid cedar]

Setting the culling mask to an unused layer also helps a lot with performance

[faint fulcrum]

Yes, I'm aware and doing so already. But it could be useful in worlds having the shadows toggleable. Some effects break without depth information (water distortion in my case) so a full material swap is also needed

[past pewter]

ideally you set up the directional light on your avatar like this https://camo.githubusercontent.com/080d4e37120125f67441f1194152099fbe1d7a85/68747470733a2f2f696d6167652e70726e747363722e636f6d2f696d6167652f666859506c59345154614767613168326c7058364f672e706e67

[faint fulcrum]

Culling layers reduces the depth prepass complexity, but in case of mirrors in my tests i still needed MirrorReflection layer active

[past pewter]

also I was reading about the unity version differences, remember that reading from a depth buffer gets less precise the further you are from origin

[lucid cedar]

Doesn't the depth buffer also rely on the camera's near and far clip planes?

For some small camera effect I remember having to set the near clip very far away to get good results, which in turn turned the camera into an "outdated 5.6 avatar" detector

Because 5.6 avatars don't respect the near clip plane and instead invert themselves

[faint fulcrum]

It does, thats why it needs to be linearized and clip rnage is used for that

[past pewter]

that's how linear depth .. oh, lukis got it 😉

that step is also the one that introduces the float precision thing

[faint fulcrum]

The common method however does not work in mirrors because they have clip planes modifed (Thats why im informing of a different method, the depth detection is just a small bonus thing ive tried to achieve)

[past pewter]

yeah it's neat, thanks for sharing

mirror clip and projection is weird but detectable

[faint fulcrum]

I guess calculating clip ranges and comparing to ones reported in _ProjectionParams can be also used to detect if rendering on a mirror, but that can false-trigger at perfect alignemt

[past pewter]

you probably saw this before too bool IsInMirror() { return unity_CameraProjection[2][0] != 0.f || unity_CameraProjection[2][1] != 0.f; }

robust way to check if you're in a mirror

[faint fulcrum]

Yeah, simpler than actually trying to extract clip values😅

[past pewter]

cool 😄

[lucid cedar]

That snippet can be used for some neat effects too

And apparently it's necessary if your shader uses VFACE

I think that's what it was called?

I think I had to use it once when i wanted a different inside texture but it was flipped in mirrors

[past pewter]

I had my mirror image bleed from the eyes during halloween 😇

oh yeah the VFACE is the flipped projection bugging out

[lucid cedar]

Oh that's cool actually

I simply had an avatar whose skin didn't render in the mirror, clothes still did

[tired token]

@faint fulcrum Quick gripe, but why redefine UNITY_MATRIX_P?

[faint fulcrum]

Completely optional, did so only to make the name shorter

[stiff berry]

const static float hz = 0.21582022;// what the fuck? 
const static float zeps = 0.000001;
bool depthgray = abs(z-hz) < zeps; // evil floating point bit level hacking
bool depthconstant = fwidth(z) == 0; // 1st iteration
if (depthgray && depthconstant) return float4(0.25,0,0,0.25); // 2nd iteration, this can be removed

sorry had to meme that

(https://en.wikipedia.org/wiki/Fast_inverse_square_root)

[faint fulcrum]

Alright, alright, I'm removing that nonsense :D
Ask unity about that 0.21582022 😛

[stiff berry]

i tried to figure out where that came from, GammaToLinearSpaceExact(0.5) is almost that number

0.21404114048

it's probably something to do with that

hmm i bet if you change the color space from linear to gamma it will actually be 0.5

[faint fulcrum]

I tried to figure too and was suspecting the same, but did not hit that function

Yup, getting ~0.50196 in gamma space (Why did I go lazy and not actually try before..)

[fiery field]

Is there a shader that make the model like it play at a lower frame rate?

[stiff berry]

i think you can use dynamic bone update rate to achieve that

like a dynamic bone on the root that doesn't actually stretch or lag behind at all

then change update rate to be really low

[little moon]

how can i fix this?

Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)

[past pewter]

@little moon what is your shadermodel target? #pragma target x try a newer shadermodel

[little moon]

sry i have no clue what that means

its not my shader

@past pewter

[past pewter]

that's how you can fix that, whatever the shader is doing is not supported by the shadermodel you are targetting

there will be a line in the shader saying `#pragma target x.x', you can edit that line to a different version that supports whatever the shader is trying to do

https://docs.unity3d.com/Manual/SL-ShaderCompileTargets.html

[little moon]

there is no line that says #pragma target

[lucid cedar]

I think if not given, it's implied.

This error generally means you have an error in one of your passes/subshaders

Not that your target is set wrongly

Any other errors when you click on the shader itself?

[past pewter]

if you have an error in your passes it shows that error

[faint fulcrum]

Also can be caused by unity disabling some stuff https://discordapp.com/channels/189511567539306508/534472629013315606/548079230253269002

[little moon]

Parse error: syntax error, unexpected TVAL_ID, expecting TOK_SETTEXTURE or '}'

[stiff berry]

post the line from the source code it's telling you the error is on

[lucid cedar]

Usually just a missing bracket, parenthesis or whatever

[little moon]

i dont know anything about coding

how do i fix that

[past pewter]

learn to code

I mean, eh, it would help when debugging stuff

[lucid cedar]

Coding basics is pretty much a prerequisite for hand-writing shaders

[stiff berry]

ya i mean it's probably not the best idea to try to fix someone else's code without any knowledge

i hope that's not just some shaderman error 😞

[past pewter]

don't get me started on people sending me those.....

http://www.alanzucconi.com/2015/06/10/a-gentle-introduction-to-shaders-in-unity3d/

you can try adding a cheeky '#pragma target 4.0` but other than that ... oof

[little moon]

in what line do i add it

[past pewter]

under CGPROGRAM

[little moon]

there is no cgprogram

[past pewter]

then its not a shader

[stiff berry]

i mean i guess there could be GLSLPROGRAM

or could be HLSLPROGRAM

[past pewter]

it could be shaderman or maybelline

[lucid cedar]

Well some shaders lack a CG block

I don't understand the syntax for those, usually some surface shader magic

The ones with a Category { block

And then SetTexture { in a pass

[stiff berry]

expecting TOK_SETTEXTURE 🤔

sounds like what it is

well maybe not cause it's expecting that

🤷

[past pewter]

it could be anything, there's unparseable code in the shader, it's not 'his shader', everybody is just wildly guessing

sounds like a botched copy paste job

[crystal wadi]

so any one ever work with HAOSR textures from unreal engine shaders , they are a combined height , occlusion, detail and roughness texture data map but readable from a single pass in a single texture

[lucid cedar]

Reminds me of Alloy's Packed Maps

They have metallic, roughness, specularity and AO in a single texture

Probably a bit more performant than Standard's approach which essentially wastes color channels on modern desktop platforms

[crystal wadi]

the key idea for this is to have the HAOSR texture animated similar to a water or hair shader so its breathing

do you have a custom shader for this ? something i can use for translating this data

i try importing on grey scale normal helps but standard shaders just cant control the settings ah

[lucid cedar]

I think Amplify is the way to go for this one

[velvet sorrel]

Yeah. If you want to use custom packed maps and can't write it yourself, Amplify makes it very easy!

[past pewter]

anyone got docme shaders?

[lyric sinew]

does anybody know of a way to implement a reflection probe or something along those lines for use with materials/shaders on an avatar? I was about to upload, but saw vrc will remove the default system's reflection probe.

[grave hatch]

@lyric sinew you would need to have/make a shader that takes in a cubemap in place of environment reflections

[lyric sinew]

@grave hatch yeah, thank you for the response, i just came to that conclusion too while asking the lighting channel. thanks!

[past pewter]

What shader let's you have emissions with pulsing effects?

[steep swift]

Poiyomi's toon shader should support scrolling emission.

[lucid cedar]

And also pulse

But I think you can make any kind of emission pulsing with an animator

[past pewter]

okay thanks

[ancient chasm]

is it possible to change shader properties in-game using emotes?

[last token]

yea

[ancient chasm]

what's the keyword to search for?

[steep swift]

Yes it's listed under (Skinned) Mesh Renderer and all the _ properties in Material

[last token]

if other shaders share the same property or use the same property behind the scenes, however, it will change it for any others that are on the same object

[steep swift]

In Body

[last token]

for example if it is the diffuse property and u wish 2 change the color of a single material

u would end up changing all material colors

[ancient chasm]

that's fine

[last token]

kk just saying

[ancient chasm]

how do I tie it to an emote/gesture?

[last token]

u use animation overrides

same way u would make any other emote or gesture keyframe

[ancient chasm]

hmm i see

ok i will give it a try

thanks!

[last token]

if u want a toggle/cycle ur gonna have 2 use something different

yw

[ancient chasm]

also another question

is it possible to select from a range of values in-game? for example, let's say I want to choose the RGB values for my shader in-game. sounds complicated, but I just wanted to check

[last token]

wym

with animations u would only be able to do that if the shader itself had separate components

or u had animations for every combination

or again a cycler

but cycler sync sucks

[ancient chasm]

right, so you mean it needs to be tied to animations or be cycled

which makes sense

[last token]

ye again unless ur shader has r, g, and b in separate properties

and again if u want 2 toggle it or cycle it thats a different process

[ancient chasm]

i was giving an example

more generally, i was wondering if there was a way to pick and set a value of the property of a shader in-game. for example, the property has a range of 0-100, i would be able to set it to any value in that range in-game

[last token]

yes

but only for while that animation is active

unless using the processes for the other things

[ancient chasm]

right. i think I get what you mean

thanks for the help =)

[steep swift]

Worlds or avatars @ancient chasm are you able to use a camera?

There are a few ways to have analog values/pickers so that's why I'm asking. Also local or synced?

[last token]

im sure they mean avatars, they said emotes/gestures

[steep swift]

For avatars there are some easy ways depending on what you are using it for: put a gesture on fist: this is an analog control and lets you choose pretty precisely between 25 values at least on vive through holding the grip precisely. use your avatar (actually hips) orientation - nice for FBT users. Time based animators for each of r,g,b that are attached to a gesture and otherwise freeze in time at what you selected - roughly what wulfe suggested. More advanced: Rigid body bone disabled by default, activated by a gesture and attached to your hand, using a skinned mesh to access the position/rotation of that bone relative to the rest; grabpass and a ui to store information on the screen (poor performance)

[last token]

i think those are a bit more convoluted 0.o also yes but that would mean the shader would need to interpolate things based on the value (for the first two)

[paper parcel]

Guys hello there! Can any1 help me? What kind of shader i need for apply to my mesh (mesh particle) to see texture (alpha\transparent) on another mesh where i place my shadered mesh? I try to use like bullet that collision on object and explode and want to place on another objects (avatars too) my own textures like smoke and blast marks on them but not see this textures in air or empty space (only on meshes). Did anyone know how to do this? See several times shaders like this... But dunno it name or dunno how to actually do this kind of effects.

[last token]

u would have to do something called projected decals/images

using the shader

[paper parcel]

@last token https://stokesmagee.net/store/product/16-lit-projective-dissolve-shader-lit-particle-decal-shader/

Like this?

Can it work in vrchat?

yes something like that

and depends

oh kk thx try search for it now ))

[somber widget]

what could cause my avatar to render with fallback shaders in my own camera and my own first person view, but render correctly in the menu avatar preview and in mirrors?

[steep swift]

You may have a bug when SINGLE_PASS_STEREO is enabled

Oh in avatar preview too. That's weird

Also your own handheld camera has the same layer as mirror and also not stereo.

You sure it's a fallback? If you comment out the Fallback line of your shader it should be pink in that case

[somber widget]

well.. it becomes the standard shader instead of using arctoon for whatever reason

and only in one specific world it seems

[steep swift]

Oh it could be lighting related. Possibly the world has fog or vertex lighting, and your shader declares support for those using #pragma multi_compile_fog or so on but doesn't compile in that case

I don't know anything about vertex lighting or whether a world can be set up to use that instead of normal forward lighting. Do you know which world it is?

(I'd still be curious what happens if you edit arctoon and remove a fallback line from the bottom. Also what makes you think it's falling back and not just applying something like a funny looking screenspace AO

[somber widget]

hmm. it could just be a really weird looking interaction. the world is https://en.vrcw.net/world/detail/wrld_e828edb9-39b8-49c5-b834-2d870128ff1a

I'll ask the world author next time I see him I guess

[thorny cedar]

Anyone know how I could make one of those shaders that makes an image show on another person's screen, I basically want a little tf2 trade request to show up in the left side of the screen.

[silk gorge]

It's not cool to put stuff on other people's screens. Please don't.

In VR it can be painful to look at.

[thorny cedar]

good point

nevermind then

[silk gorge]

making it appear as a particle floating in the world might work just as well for the joke

[thorny cedar]

true, that might be the best way to do it then

[silk gorge]

And it can be billboarded so it faces all viewers looking at it

[thorny cedar]

k, ill look into that, thanks for the advice

[ancient chasm]

Thanks for the help @steep swift

i tried looking at the skinned mesh renderer for the material shader properties, but it didn't show up... I think it's because the material and shader are ones that I created in Unity and not imported from Blender. Any Unity tips on how to add them to the skinned mesh renderer?

[last token]

is the only way to make a flashbang-like or drunk effect to draw a grabpass onto a temporary texture?

[faint fulcrum]

Almost done with near-full-featured standard shader with geometry pass and just figured one quirk about emission used for lightmapping.
https://docs.unity3d.com/ScriptReference/MaterialGlobalIlluminationFlags.html
EmissiveIsBlack must not be set in the material and need to clear it either by script or via debug inspector.

@lucid cedar This could be why your screen emissions were not being picked up

[lucid cedar]

Ohh, I see. Thanks! I'm currently rewriting the shader so I'll keep this in mind.

[lucid cedar]

I'm trying to scale an object in the vertex shader like this:

v.vertex *= _ObjScale;
o.pos = UnityObjectToClipPos(v.vertex);

However, this seems to scale the object by its center, meaning that the object will be half in the floor. Is there a way to scale it by its origin point instead?

[last token]

yea

find the direction of the vertex from the origin

v.vertex += outDir*_ObjScale;

[lucid cedar]

Alright, and how do I do that? I tried looking up how to get the origin point but pretty much zero useful results

[last token]

isnt the origin point <0,-size/2,0>

[lucid cedar]

¯_(ツ)_/¯

[last token]

also i dont think that would work very well

considering it would clip out a lot bc of the AABB

unless u set the AABB to not cull

[lucid cedar]

Bounding box size is not an issue right now, it's only for small adjustments

[last token]

o

[lucid cedar]

Not sure how to get outDir

[last token]

i mean just make ur own value

where u can specify the center

cuz its in object space

and outdir is like

normalized(v.vertex - originpoint)

or whatever u do 2 normalize in unity shaders

[lucid cedar]

I'll try that, thanks

[last token]

yea just add a property where u can put the x,y,z

[past pewter]

that will not work and warp the object

your scaling is correct @lucid cedar, just raise the object ]

[last token]

y would it warp

and does that just mean

v.vertex += v.vertex * _ObjScale + offset

[lucid cedar]

Is there a way to know the right value to raise/lower it by? It floats when I scale it down. Ideally I'd want a solution where it just behaves like the game object scale @past pewter

[last token]

here if u have the offset calculated

v.vertex += (v.vertex + offset) * _ObjScale

it like the other one except the offset scaled also

so if u know what offset from center

it should scale from that point

[past pewter]

you want uniform scaling though, not warping

[last token]

doesnt that do uniform

it just scale from an offset instead of scaling from <0,0,0>

o wait u would need to change it so that

vertex*_ObjScale + offset*(_ObjScale - 1) or sumting

instead

cuz at scale of 1

should have no offset

[past pewter]

learn about world space, object space and local space

[last token]

which is same as vertex + (offset - vertex)*_ObjScale

[past pewter]

you are not respecting those and just moving the verts with an offset

screwing up localspace

[last token]

i mean if u wanted 2 transform all the verts in object space

wouldnt u just use vertex += offset

[past pewter]

learn about matrix transforms and going from one space to another

[last token]

i mean arent the .vertex already in object space

[steep swift]

@lucid cedar I believe the origin is defined by the mesh independently of the value put in the bounding box field. Based on your question I'm going to assume you are talking about skinned meshes. For Skinned Mesh Renderers oddly it appears that the center is not the position in the unity hierarchy (this is ignored) but rather the transform of the Root Bone. If you want to adjust it you might be able to set the Root Bone to be your Armature instead of Hips

If you're talking about an ordinary mesh, you are probably best of adjusting the origin point in blender and moving them appropriately in unity (you can assign an Anchor Override to an object at the old center point like Hips if you want to keep lighting the same)

Forgive me if I'm wrong but I've been confused about this before and I'd not be surprised if my understanding about this is still wrong despite making a shader that heavily depends on the object space origin

[lucid cedar]

Ahh, I see. That might explain a lot. Currently it's a skinned mesh and the root bone is indeed the hips

That would explain why it's doing this

[steep swift]

I don't know if you can change it safely but they have a UI for it so maybe give it a try

[lucid cedar]

Yeah, I'll try changing it to Armature and see what happens

[steep swift]

Most properties of skinned meshes aren't exposed in the editor

[past pewter]

@steep swift nah, you're right, if you want to scale an object, you keep the center/local origin in the center or any transformations later on will mess up/end up in the wrong position

offsetting the verts is a disaster and bad advice

[lucid cedar]

Do you need a "Meta" pass, especially for regular toon shaders?

There is 0% chance of me or anyone else actually using this for lightmapping

[paper parcel]

Hello there! Try yesterday to find decal shaders.... Only found reprojectors (they don't work in vrchat) and not worked as well shaders.... Did anyone know - where i can find working in vrchat decal shaders (to apply in particle meshes and mesh objects to interact with avatars)

[ancient chasm]

my shader isn't being reflected in most mirrors, is there an option that I have to enable?

[lucid cedar]

Does it use VFACE in the fragment shader?

It's inverted in mirrors @ancient chasm

[ancient chasm]

I don't have it in the fragment shader - I have Cull Off ZWrite On ZTest Less

[lucid cedar]

Shouldn't ZTest generally be ZTest LessEqual?

[ancient chasm]

Honestly I am noob so it's from a sample shader that I copied

[tired token]

@lucid cedar You mentioned reflection probe checking in #development-advanced , I can't remember if you do shader stuff but the alpha channel of the probe sample (not the decodehdr) is 0 if it can't find a probe (skybox is a probe)

[lucid cedar]

Ah I see, good to know

Thanks

Actually speaking of shaders, I'm doing a toon shader but it currently doesn't react to the light color. It only takes the light intensity and color intensity in account. What's the "correct" way for a toon shader to handle light color, does anyone know?

Multiply the color by the light color?

[tired token]

Quick note, I have no idea what the alpha channel is actually for but I did notice that 'feature'.

[lucid cedar]

I probably won't be using reflection probes on any of my own shaders soon, but it's good to know. Maybe I can use it for debug purposes

[faint fulcrum]

Cubemaps are RGBM encoded - alpha is magnitude and DecodeHDR takes care of colors.
Not sure whats in alpha with non-HDR cubemaps/probes.

[tired token]

I guess checking for 0 still works then.

It's seams to be 1 visually.

[faint fulcrum]

Non hdr probe cubemap shows up as DXT1 so might be implementation specific? 🤔

[past pewter]

@lucid cedar if you make worlds, if you add any reflection probe it will only work inside the zone for it, that's why in a lot of maps it can turn black (you left the zone of the 1 ref probe that was specified) ... the fix is to make one of the reflection probes cover the whole map so there's always something to read

[grave hatch]

@lucid cedar yeah you'd wanna multiply the light color by the surface color

you can use the default shader as reference
taking say a red object and a cyan light would turn the object black

[steep swift]

Ref probes are black and don't default to the skybox?

[past pewter]

@steep swift when you don't add refprobes to your world it's the skybox, when you add a refprobe but go outside their zone, it will be black since there's no fallback global refprobe

just the area of the one you added will read as a refprobe in your shader, outside it will read pure black

[last token]

dont some shaders let u specify a custom fallback

[steep swift]

What's your question exactly? Are you asking about unity subshader fallbacks (unsupported hardware or error) or vrchat safety system fallbacks?

[last token]

some shaders such as xiexes

let u specify 'PBR fallback cubemap'

[somber widget]

is there a way to tell in a shader the relative vector to the viewpoint position that takes into account mirror reflections?

[steep swift]

The camera (view position) is the position of your reflected position in a mirror (going "through" the mirror). However for effects that want to use this you may want the average of left and right eye #if USING_STEREO_MATRICES ... in mirrors you do not use single pass stereo so cannot access each eye

[somber widget]

hmm. I've been trying to react to when the relative angle between the viewpoint position and the vertex normal is smaller than a threshold using dot(normalize(ObjSpaceViewDir(v.vertex)), normalize(v.normal)) > cos(radians(angle)) but it never seems to be triggered in a mirror at all...

will look into USING_STEREO_MATRICES though

[steep swift]

float3 leftEye = unity_StereoWorldSpaceCameraPos[0];
float3 rightEye = unity_StereoWorldSpaceCameraPos[1];

float3 centerEye = lerp(leftEye, rightEye, 0.5);
#else
float3 centerEye = _WorldSpaceCameraPos;
#endif```

I can't tell you why mirrors would behave differently there... except maybe normals being inverted (due to being reflected and with flipped culling)

[somber widget]

hmm

[steep swift]

Oh so if it's flipped that dot will always be negative, while normally you can't see polygons behind you

So you could throw in an abs()

[somber widget]

I'll try just using a Y vector translated to world coordinates instead of normals

[steep swift]

I saw v.normal

[somber widget]

I was using v.normal 😃

[grave hatch]

Is it possible to write the Zbuffer value from the frag function?
Since from my understanding it's per pixel
I'm messing with raymarching and I want it to act like normal geometry

[steep swift]

Yes you can add a parameter in your frag function , out float depth : SV_Depth

[grave hatch]

any specific parameter I need for ZTest and ZWrite?

[steep swift]

https://stackoverflow.com/a/34535613 implies to use ZTest Always ZWrite On and use an early render queue. I imagine you could try to do the discarding yourself if you know something about the scene

[grave hatch]

alright I'll look into it, thanks

[steep swift]

There's also SV_DepthLessEqual(depth) to test against the depth buffer

[grave hatch]

ah I got it working, thanks
link also had something about getting the depth from clipspace with the raymarch which was something I had in mind but wasn't sure how to do

[waxen pagoda]

would anyone happen to know what the virtual boy racoon uses for its shader?

its like the xray thing in the Avatar Testing world but red and black and is more solid

[somber widget]

@steep swift I figured out why my shader wasn't working in the end, somehow in mirrors it was getting backface culled (probably because it's using a billboard vertex shader but not recalculating normals accordingly), so turning culling off seems to have fixed things. Thanks for the stereo viewpoint averaging tip btw

[faint fulcrum]

@grave hatch preferably use alphatest render queue with that shader - before transparents so depth is actually written and after opaques to keep early-z optimisations

[restive vessel]

hey does anyone know how to make the name tag in vrc invisible?

[ancient chasm]

@somber widget was your shader not showing up in mirrors?

[somber widget]

@ancient chasm　yes, turning off backface culling did the trick. I'm manually culling it using camera view angle anyway so no point in the normal based culling

[lucid cedar]

VFACE is reversed in mirrors @somber widget

Maybe I already told you that

So if you use the view angle that could have been causing it

[somber widget]

Ah yeah, that'd do it for sure

[lucid cedar]

There's a way to check if you're rendering in a mirror in the shader

[somber widget]

I don't think I need that. It seems to be working properly now :)

[ancient chasm]

ok.. my shader isn't showing in mirrors. still gotta fix it

[steep swift]

Materials with Cull Back set will be switched to Cull Front in the mirror. Needed since polygons render clockwise and in the mirror they become counter clockwise

[ancient chasm]

Cull Off turns Backface Culling off, right?

[last token]

no

Cull chooses which sides of a polygon to cull

Cull Front culls front faces

Cull Back culls back faces

Cull Off doesnt cull either

[lucid cedar]

Cull Off would then turn off culling altogether which is generally what people want when they say "I want backface culling off"

[ancient chasm]

ok. i have Cull Off but my shader still isn't showing in mirrors

[steep swift]

What does your shader do? Are you in vr or desktop? If in VR, Does it show in your handheld camera?

If you are doing certain things related to particles or material changes, those will not show in your own mirror reflection

The camera "mirrors" on the volt dancefloor are set to also show PlayerLocal layer so that would be another interesting place to test it

[ancient chasm]

it's a pixel shader, in VR

it shows in "camera" mirrors, but not mirrors like the Nier World mirror

[steep swift]

Does it show in your handheld camera

[ancient chasm]

it's actually a shader that I attach to a particle

so maybe that's why

[steep swift]

"Photo Camera" or "Stream Camera"

[ancient chasm]

handheld camera as in those handheld cameras in custom world?

[steep swift]

No in the menu Cameras

If you are in vr

[ancient chasm]

oh hmm

let me check

[steep swift]

Those use the same MirrorReflection layer that vrchat mirrors use, as opposed to world cameras that often leave all layers checked

[ancient chasm]

it doesn't show

in the photo camera/ stream camera

do I need to write something in my shader particularly to get it to show up in mirrors?

actually I guess I can test it by putting the shader on another part of my avatar instead of a particle '

[steep swift]

No it's due to it being turned on from an animation

MirrorReflection shows your head but because of that a lot of animations don't affect it properly and some things don't show for you

Everyone else will see you fine. It's just the usual evil twin mirror shenanigans

[ancient chasm]

🤔

So it's because of the animation?

[steep swift]

https://vrchat.canny.io/bug-reports/p/mirrors-do-not-reproduce-mesh-togglesanimationsparticles-properly

[ancient chasm]

oo ok

[steep swift]

It's a long time bug- not much you can do about it unless it's enabled by default

[ancient chasm]

haha it's not a big deal

[steep swift]

I think mesh toggles do work

[wild oxide]

i believe mesh toggles dont work but togglign the entire object does

oddly enough it used to be the other way around

if u wanna check 100% it should work on world cameras (actual cameras like in avatar testing) and would also work if using holoport motion and moving into third person

[astral plover]

Anybody know where I can get ahold of a screen whiteout shader for my world?

something that I can animate to fade your vision to white

[last token]

should take like a couple of seconds to make one

just make it render on top of everything and output pure whote

probably a bad idea for vr users tho

[acoustic oak]

maybe black instead of white... white would just be annoying and hard on the eyes

[astral plover]

Unfortunately I don't know the first thing about making Shaders

[steep swift]

You can play around with shader forge or amplify if you want to get started with a graphical approach. Also about bad idea for VR users, tell that to vive which flashes blue light into my eyes every 5 seconds for no reason in laggy worlds. I hate that so much

[last token]

[lime widget]

I saw a water surface shader that reacted to objects (and particles) to collide with it today, I would be curious into knowing how something similar can be archived without using custom scripting.

Don't worry, I'm not asking about a tutorial or anything here, just hoping for a few technical keywords that can lead me into the correct direction ^^

[past pewter]

@lime widget it works with a camera overhead or under the water filming the surface of the water onto a texture

the water has a shader that reads that camera texture and does ripples etc

[lime widget]

Oh, so just a camera with near and far clipping to match the distance of the water surface?

[past pewter]

yess you got it

then match the UVs on the water material to the camera feed

[lime widget]

Awesome! Thanks, I would not have come to that conclusion, I'll definitely write this neat little trick down for the future ^^

[past pewter]

you also want a feedback system so you can interpolate the last frame of the water ripples

and you can do that with another camera or double buffered custom render textures

[lime widget]

About a year ago I tried myself at shader programming, became horrible headaches from all the math involved and decided to leave it be...

Looks like it's time for headaches again, lol

[past pewter]

so when you select culling layers for the water camera, you're essentially picking layers that will interact with the effect

[lime widget]

Yep, I got that

Which is pretty awesome

[past pewter]

(players, pickups, particles etc)

there is a couple of examples of this around to examine

[lime widget]

I just joined the builders club today, and am only on VRChat for 2.5 days, I'll need some time to get into it, but I can definitely see myself making quite some awesome content in the future

it's the one used in the hot springs world

[lime widget]

(Wait, on another note, did that guy record himself through an ingame camera? o.o Can you store the output of a rendered texture to a file? :D)

And yeah, I've been at that place, that's where I saw it ^^

[past pewter]

dunno about streaming a rendertexture to a file in the editor

i guess you could script something like that (in the editor ofc)

[lime widget]

Oh, I'm certain that it works in Unity, I'm just curious how that person made the video 😛

[steep swift]

@lime widget the link in that video might point to an older version. you're going to want SilVR 2.0 (download link is on [redacted] or in the prefabs database in pins of #world-development ). Also you can use the ingame stream camera to capture stuff on the desktop window without interrupting VR, and capture that using OBS. It could be that's how it was recorded.

[lime widget]

Hey, sorry for the weird question but where is [redacted]? :D

[fading schooner]

Does anyone have some advice on shaders for robotic characters? I'm having a bit of trouble finding a nice one that's sort of inbetween shiny realism and cartoony. I've seen people with some good ones in game though.

[steep swift]

I'd highly recommend a standard setup, various matcap or specular setups could work for metallic surfaces. If you really want Toony, you should take a serious look at XSToon by Xiexe. It is a toon shader but also designed to have the same lighting and most capabilities from Standard, including PBR and Matcap or metallicsetups. So if you get something that looks good in standard it should be possible to make the same thing work in XSToon @fading schooner

[fading schooner]

@@steep swift Thanks for the help I'll try that 😀

[halcyon kestrel]

I'd like to add to what Lyuma said and say that the rewrite, which is coming out soon, will 100% fully support the way standard looks, as well as toony.

I.E. you can set up a material in standard shader, switch to mine, and everything will transfer, or should transfer, pretty seamlessly.

You can then adjust your ramp etc to make it toony or just use the extra features such as rim lights, shadow rims, etc.

[crystal wadi]

@halcyon kestrel have you had time yet to look at the new bakery shader non linear light probe SH

[halcyon kestrel]

I've been expirementing with it a bit, yes. I've also been expirementing with directional lightmaps specularity using bakery, and that seems to work just about as well, assuming the shader supports it.

[crystal wadi]

nice

[past pewter]

anyone know here how to convert glsl to hlsl

[steep swift]

unity ShaderLab has some custom #pragma lines to declare which function is your fragment and which is your vertex function, instead of using void main()

just did a simple google search and got this page https://anteru.net/blog/2016/mapping-between-HLSL-and-GLSL/ for a list of which functions are different.

Variables are float3, float4x4 instead of vec3 and mat4, for example. and instead of using global variables for varying , you use struct elements with a semantic like :TEXCOORD0 and instead of writing to gl_FragColor you return the color and declare your frag function "float4 frag(v2f input) : SV_Target {"

look at some examples and you should be able to pick up most of the differences. that blog post should cover most of the stuff that isn't obvious (like function names)

[lucid cedar]

Automatic translators will not always do the job well

Your best bet is reading and understanding what the GLSL does, then rewrite it in HLSL.

This goes for those shadertoy shaders, too.

[lucid cedar]

You're assuming I already have something like that premade

[past pewter]

Why not

Rokks allin1 toon shader

Gib

[lucid cedar]

I tried making a simple toon shader but I realized the lighting is too difficult for me to grasp so I went with PBR

[past pewter]

Ah

[lime widget]

What ways are there to make my shader "win" the clipping battle against another?
Example:

The best solution so far was setting the ZWrite of the shader to "Always", however that resulted in it to also be drawn over objects in front of it, which was not ideal. I'm quite new to shaders and will need some time to get into it, especially because I'm not the best at math which seems to be a skill that is quite useful for shader programming

I would assume that changing the Render Queue value in the Shader (Or Material properties) would be a simple way to resolve issues like this, however it seems to not have any effect on the situation.

[grave hatch]

put the one you want to "win" have a higher queue value

so it'll render after

you can do that in code by something like

"Queue" = "Geometry+1"

In the shader tags

[faint fulcrum]

Wouldnt it still fail ZTests?

[grave hatch]

or just raise the mesh slightly above it

[lime widget]

Yeah, I could raise the mesh, but I think it has more educational purpouses for me if I try to make it work with the shader ^^

[grave hatch]

ah yeah nvm the queue thing doesn't work for that
you can use offset though
https://docs.unity3d.com/Manual/SL-CullAndDepth.html

[lime widget]

That's actually what I just found as my solution 😄

Works like a charm. Offset -1,-1 solves all clipping problems for me.

[lime widget]

Thanks for your help, it was definitely valuable today ^^

[past pewter]

please don't share crap that gets you reported

nobody likes those being used

I don't mind people finding out how, but this makes it too easy for people to use them 😉

[fluid hamlet]

someone knows how to use the Vilar’s eye tracking shader ?

and can tell me step by step (or point me a detailed tutorial vid for it)

[lucid cedar]

I think his Github repo or the vrcat thread has a dedicated tutorial

You need to turn the eyes into non-skinned meshes that are parented to the head bone

And run the eye tracking setup in tools

[frail abyss]

Hey everyone! I have an interesting result that I'm chasing after and I think at least for VRChat the process to get their lays in the use of a shader. It's a "surface" placed in an environment that acts as a real-time camera into another space. It would function like this: https://www.youtube.com/watch?v=90DRrYZp37c&feature=youtu.be&t=17

If this truly is a shader-related issue, is there anyone that has some tips or full-out solutions for achieving this effect? I've seen it before in VRChat so I'm confident that it's doable, just am not very skilled in writing code, let alone for shaders.

Passing through is not the primary goal, just the ability to see into separate free-standing space.

[lucid cedar]

Seems like something you could do with stencils.

You would essentially have both sets of geometry overlaid at once. One has a stencil with Reference value 1 and comparison NotEqual, the other set of geometry has a stencil with ref 1 and comparison Equal.

Then when you look through geometry that writes 1 to the stencil buffer, you can see the other set of geometry through this frame.

[frail abyss]

Will this involve the use of a camera?

I'll take what you said and try to find some unity tuts for it as well

[lucid cedar]

No cameras necessary

Which is what makes it a rather clean solution since the geometry will actually be there

I can foresee some issues with lightmapping though

Perhaps you'll need to put them on separate layers and adjust the culling masks

[frail abyss]

Right on, I'll work on it soon. Thanks!

[steep swift]

@frail abyss check out the world called spatialgate demo

[glacial siren]

I know barely anything about shaders but i wan't to try to solve this anyways...
I'm trying to make a weapon appear using a special shader that gives a reverse dissolve effect, the problem is that it isn't a double sided shader.
usually i'd double the normals but it's already a ton of polygons, on top of that, i can't reduce the polygons on the weapon at all due to how complicated of a mesh the weapon uses.
the only solution for me is to turn this dissolve shader into a double sided shader, i turned culling off, but now i need to fix the lighting, what do i do?
I get the feeling this is going to be much more complicated then I think it's going to be...

[near flax]

what's wrong with the lighting?

also keep in mind that you don't necessarily need to double all the normals, only the parts that need to be double-sided

[glacial siren]

sadly, that's all of them T_T

anyways, basicly the lighting on one side of the polygons is fine, but the other is really REALLY dark

so dark that it's almost pitch black

[tired token]

Invert the normals based on the vface direction.

Here's a thing I did to fix it.
ps ty Merlin for idea
https://github.com/Xiexe/Xiexes-Unity-Shaders/blob/master/Main/CGIncludes/XSVertFrag.cginc#L97-L108

@glacial siren Here's a mention for it^

[glacial siren]

Here's a thing I did to fix it. I would use that, but I HAVE to use the dissolve shader because it allows me to have a dissolve effect that i'll be using for the animation to summon the weapon

and as for inverting the normals...

[last token]

also yea lighting is based on vertex normals

if u show the normals in blender

it show blu line pointing away from vertex

[glacial siren]

heck https://i.imgur.com/VrXPdqK.png

[last token]

if u use smooth shading it gonna blend the lighting

[glacial siren]

https://i.imgur.com/qbQ5wlK.png no

[last token]

so if u hav a normal that point away from light

it blend a dark color

[glacial siren]

no, more like the lighting itself is inverted for the opposite side

[lucid cedar]

You'll have to edit the shader probably

[glacial siren]

which i have no idea how to do, not without a ton of help

this is the first time i've ever even touched shader coding

i don't even fully know which part of the coding i spammed "cull off" into did the trick to actually turn cull off, or if they all did

i can post the code of the shader if need be

the point of the shader is that there's a slider that when you move it will give the item a dissolving effect.

[last token]

o ur gonna have 2 do stuff against shadows and such

that or u can just double faces only where needed

[glacial siren]

to be honest, i don't know which option would be harder, and that fact scares me since i'll have to do this multiple times with multiple keyblades O-O

[tranquil belfry]

Would anyone know of like a sparkle shader? Can change the color n such?

[hasty patrol]

I just downloaded Xiexe's Toon Shader and am comparing it to his older versions. The new version is making shadows very dark and I believe this to be caused by using world lighting. I remember a dropdown in an older version (1.4) that allowed to to switch off of world lighting. I am not seeing this in the newer version. On VRCat, he describes this issue and recommends "resetting the material". I'm not too sure what is meant by this. I created a new material from scratch and applied to my avatar. Same issue.

[steep swift]

Can you see the problem in vrchat too? Which world?

The way to test is try Standard and see if it has similar lighting

If Standard looks very different, it could be a bug.... if standard also looks dark, it is an issue with the lighting of the world you are in

What ramp are you using?

@hasty patrol

[hasty patrol]

@steep swift That's the thing. I cant find that ramp dropdown that I remember seeing in older versions. It is the world's lighting that is affecting the avatar. I remember switching that setting in older versions to resolve the dark shadow issue.

[velvet sorrel]

Are you using his newest 2.0 version?

[wild robin]

@hasty patrol This is a result of world lighting. Right now, it isn't ignorable unless you tell your mesh to not cast shadows.

If you'd like to see a new "don't cast shadows from world lighting" feature built into the shader, you might want to try asking on the XSToon Discord.

[hasty patrol]

Thanks @wild robin! I was going to tests out not casting shadows. From what i saw from my tests yesterday, im liking xiexe’s shader. Still seeing if i can get a “fade” effect working on it for blush, tears, etc. going to mess around with it a little more today

[wild robin]

Fade works pretty well in XS2, I use it for my eye highlights and a bit of mesh that floats above my face to avoid stretching.

Make sure you set the shadow ramp on any Fade bits to a white texture/none if you don't want it to get shadow ramp'd.

[fluid hamlet]

so i was looking for the shader that is used on the totally normal hoppou , but it seems it is not Vilar’s eye tracking but more the same used on the name tags ... anyone an idea or what the code is for that

[near flax]

if you mean the one that stares at you all the time, you can definitely do that with an eye tracking shader

[fluid hamlet]

any explanation how as Vilar’s only seems to face forwards for me even with the backwards slider to max

[near flax]

i've never used vilar's tbh, i can dump mine in here tho, one sec

[steep swift]

Vilar has very specific requirements regarding eyes being separate non skinned meshes and orientations. You would have had to follow all of that

[near flax]

https://gist.github.com/AkaiMage/8238f2edd2ac5ce3ea2bb9c1964c6e7d

separate the hoppou's head as it's own non-skinned mesh with the origin of it being the center of the head

then stick this shader on it

@fluid hamlet

[past pewter]

is some one know how to add screen shaders in unity

please

[near flax]

not sure what you mean

[past pewter]

[near flax]

are you looking for a screenspace shader or are you trying to figure out how to use one?

[past pewter]

yeah

yeah

[near flax]

i'm asking which

[near flax]

i'll DM you one since people get pissy about posting them in public

[steep swift]

Also you spammed all the groups with that

[past pewter]

yo does anybody got that shader that zooms in on an avatar?

[lucid cedar]

@past pewter https://discordapp.com/channels/189511567539306508/390924344475254792/550065919364169743

Zoom shaders are obnoxious and very nauseating for VR users. You won't find anyone here willing to help you with that.

I get that "haha funni zoom xd" is fun on desktop but it isn't in VR.

[fluid hamlet]

So i came across a mmd shader that creates a wet skin look ... but its .fx can i still use this or do i need to convert it somehow and if so how?

[lucid cedar]

You can't really

[steep swift]

You can probably take inspiration from it... the lighting model is very different but some things are quite similar between shaderlab and mmd fx.

What's the name of the mmd effect you are looking at?

[fluid hamlet]

this

[vale hare]

im at my wits end here. its driving me crazy. how can i get an object with a fade material to show up behind an object with a transparent/fade material?

Ive got a glass display case, and a figurine box behind it. but the box for the figurine, for the "plastic" on the case to work, is set to fade.
But this causes problems, and no matter what I do, i get one of the following issues:
the box shows up full strength behind the glass, ignoring it,
the box disappears behind the glass
or the box shows but the figurine inside is overpowered and culled by the box itself.
and to top it off, sometimes it will look right in unity, but then ingame it gives me one of those issues.

why is this so difficult

[lucid cedar]

What kind of shader are you using?

@vale hare

[vale hare]

at this point ive tried mix and matching several. standard, cubed, poiyomi, noe's, hell, I even tried tossing arktoon in there.

this is the goal. and like I said, I often get it to look fine in unity, only to have vrchat disregard that.

Ive tried messing with render queues too, with again, vrchat often disregarding the changes

[lucid cedar]

Render queue changes don't work at all on anything other than Standard

Custom render queues set in the material don't work

It always uses the shader's "default" render queue, except for Standard and Standard Specular (roughness has the same issue)

[vale hare]

not to mention the issue with changing the render que, is that if I, say, change the render que so that the glass renders over it, across the hall there is more glass that then renders on top of the box from the other side

also you say render que changes work on standard?

[faint fulcrum]

Only render queue specified in the shader itself will be used Tags { "Queue"="Transparent"...

[lucid cedar]

Render queue changes don't necessarily work on standard

It's more likely that the "Transparent" dropdowns are accounted for, is all.

If you use other shaders they need to have a "dedicated" transparent version

But it sounds like that was the case if you were using Noenoe

[vale hare]

mm. to be fair I havent updated my noe's in a while, so ill try that too. see if that does anything

[last token]

are those shaders set up for lightmapping..?

because a lot of shaders dont actually work very well or at all with lightmapping (baking lighting) so it would be a poor choice for a world

[vale hare]

there isnt anything baked. (yet)

[past pewter]

anyone got the zoom shader lol?

[somber widget]

@faint fulcrum that explains so much, now I need to go make four copies of arctoon, sigh

[tired token]

Just an FYI, Arktoon has separate shaders for Opaque and Fade.

But if you do want stuff to sort properly you'll need to make duplicate shaders and change the queues

[steep swift]

Didn't see it mentioned but you can change the queue in a shader file by taking base queue and adding or subtracting like "Queue"="Transparent+1" or "Queue"="AlphaTest+1".
Also important-after duplicating make sure to edit the shader name at the very top of the shader file. @vale hare

[somber widget]

@tired token in my case I'm doing things with stencils and have been wondering for a while why it's been unreliable

[tired token]

Ah okay

[tiny linden]

Hello. I have published Arktoon-Shaders v1.0.2.2. This version have no shader keywords and variants.
I am sorry for inconvinience this keyword-limit issue. 😭
https://github.com/synqark/Arktoon-Shaders/releases

[lucid cedar]

Sweet!

Not sure what [ATSToggle] is, I'm assuming it's used in your shader's editor. Alternatively you can use [Toggle(_)] to have a toggle without generating a keyword

[tiny linden]

OMG I didn't know this

I will replace toggle(_) instead next version ><

thanks!

[faint fulcrum]

Well, when using custom editors you dont even need the [Toggle(*)]

[tiny linden]

btw, Unity adds [UIToggle] in 2018.2 that is similar to Toggle without controling keywords. is it same?

Adding checkbox by Custom editor takes more time to me 😭

[lucid cedar]

Either way the new version seems to generate no keywords, so that's good 👍

I can't find any documentation on UIToggle

[stiff basin]

im trying to ask a question but the bot keeps removing my message

[split girder]

because we don't allow mentions of the website you're trying to refer to

[stiff basin]

Oh my bad

[split girder]

no worries

[golden shadow]

Can i use any shader in a map? or is it locked like scripts?

[lucid cedar]

You can use whatever shaders you like

But sometimes, shaders may depend on scripts which won't work in that case

And obnoxious shaders or stuff that is broken in VR will not be accepted into the public

[wild oxide]

i read somewhere that shader keywords are stored on a material for past shaders applied to it. is there a way to quickly "clear" this backlog of keywords and regenerate the ones needed for the current shader?

[steep swift]

I think there are some tools floating around or at least discussion about making it easy

but I don't actually know of any....

But you can also switch your inspector to debug mode (Actually I recommend doing this and then opening another Inspector through Add Tab in the rightmost tiny button) and delete Shader Keywords

It works fine with multi-select too. Just shift-click all your materials (if you're really ambitious, search for t:material in your project directory), click the Shader Keywords line (will have a greyed out "—" in the box) and just hit backspace. That will clear it for all materials @wild oxide

now that will cause artifacts in some materials until you update them, so you need to click on each material inspector and have it render one by one. Rendering the inspector should fix any keywords that are required to be there

[wild oxide]

gotcha, thanks!

[tired token]

Fun fact Arktoon has a keyword clearer script in the toolbar.

[tender haven]

HI

[past pewter]

Hi, need help with something?

[drowsy field]

not sure how the [ATSToggle] works but as i brought Arktoon to its raw properties without the custom GUI, none of those toggles were setting auto keywords enabled which is surprising and good.

[lucid cedar]

ATSToggle is probably interpreted in the custom editor GUI as a toggle that just sets the value to 0 or 1

Which is more work but does prevent keyword use

Although [Toggle(_)] is easier

It's not documented anywhere

[drowsy field]

yeah but i commented GUI import off

the gui script shouldnt be loaded then yeah?

it was just the raw shader properties

im not sure whats going on with the [ATSToggle]

[tired token]

You're looking for line 865 ACIIL.
internal class MaterialATSToggleDrawer : MaterialPropertyDrawer

[drowsy field]

found those on search and they looked empty.

inherenting something

but then

no auto keyword naming?

which is good

[tired token]

Yup

[lucid cedar]

It's weird that Unity would auto generate a keyword like that

Considering enums don't unless explicitly specified

[tired token]

Just Unity things

[lucid cedar]

I guess it matters less in the context of a regular game

Where most people use built-in shaders, very simple shaders, and/or one very big keyword-heavy shader like Uber

Whenever I look in my logs for exceeded keywords, it's always those stupid meme zoom screenshake shaders taking up like 50% of the keywords lol

[tired token]

I made a Material to 'cache' all the Unity Standard and Post Processing Stack V1 & V2 keywords and threw it on my avatar. lol

[lucid cedar]

Lol

Is that so those particular keywords will never fail to work?

[tired token]

Pretty much

[lucid cedar]

That's cool

[tired token]

I'll never have a PP issue ever again.

[lucid cedar]

Wait, is that the reason PP sometimes fails?

[drowsy field]

its the shaders that need keywords defined and fail to work otherwise that pay

[tired token]

I believe so

[lucid cedar]

I have had cases where color grading was not applied and/or the bloom was like super bright

And flashy

After playing for a while

[tired token]

In most cases keywords are used for features, so I don't care if your shitty shader's features don't work. :))

[drowsy field]

makes me think if the pps v1 v2 shaders should be special written without keywords and solve that problem?

[lucid cedar]

Unfortunately an older Arktoon version could make a material fully metallic if keyword limit was reached

[tired token]

You can rewrite PPSv2's shaders.

[lucid cedar]

Oh wow

And that'll work ingame?

[tired token]

cough

[lucid cedar]

I can see that being very useful for certain screen effects in worlds

[drowsy field]

is it true that we are using a custom pps v2 for vrchat?

[tired token]

Yeah you can do custom things.

[drowsy field]

someone tell Reflex to clean keywords and toggles. I think its the last popular shader that needs it. More so with all the booth models using it.

i inspected the code and there are defines being used from toggles which means refactor work.

[steep swift]

I just don't see every random Joe Avatar Uploader updating their sjaders

[grave hatch]

Post processing is pretty much just shaders

[steep swift]

A public avatar world keyword check would be nice but they are going to get rid of those... or ranking system to encourage people to fix and update stuff en masse.

[halcyon kestrel]

You have to clean the materials still even after updating the shader so the keyword thing isn't going away anytime soon.

[steep swift]

The big thing for having shaders with no keywords is they won't break when something else uses up your keywords. So updating is still a worthwhile cause

[halcyon kestrel]

True facts

[drowsy field]

yeah

[past pewter]

I need help

I have cubed shader but this still appears pink

[lucid cedar]

Does anyone have a good matcap shader that supports .spa and .sph textures?

For metal.sph that you see on many MMD models, for example.

[tired token]

Don't you need Unity to import them correctly first?

[lucid cedar]

That's not really the issue, I usually convert them to PNG's by opening them in GIMP.

They're basically renamed bitmaps as far as I know. The problem is using the resulting texture in a shader

I need a good matcap shader which supports those textures

So far I've found one but it's slightly overkill and uses a bit too many keywords

I had the matcap part break on me resulting in a flat white color instead

[tired token]

Can you send me one, kinda curious what they look like.

Unless they're actually just matcaps.

[hard siren]

So guys I updated my nanachi and for some reason I have an outline (I didn't enabled it, but for some reason I can see it in vrc), how do i remove it?

[lucid cedar]

Don't use the non-lite version of Cubed's

Use the lite version or choose a different shader

[hard siren]

i use the normal toon shader

version 0.26

[last token]

wym 'the normal'

also not look too bad cuz makes ur hand actualy visible

[past pewter]

What shaders look good but don't crash people?

[crystal wadi]

standard

[steep swift]

shaders don't cause crashes, unless you have old drivers, tesselation type features or overdraw can cause heavy lag ("crashes") or running on Linux with certain types of geometry shaders like fur can crash

Standard for standardy stuff, XSToon if you want lighting of standard but a toony look with ability to set custom ramps

[past pewter]

Well I'm just scared cause someone crashed me before

Just put there hand in my head

[steep swift]

Those people are doing it intentionally. You can find their username in the output log and send #moderation-reports

Your shaders generally won't do something malicious unintentionally, don't worry about it.

[past pewter]

Got it

[waxen fjord]

Where can I get a sprite sheet overlay shader?

[past pewter]

A sprite sheet overlay shader? I'm assuming you want to use this for the sake of Particle systems, Unity has wonderful inbuilt particle shaders, which are compatible with sprite sheets, perhaps give them a go?

[fluid hamlet]

So i figured out that the totally normal hoppou avatar head is a billboard shader and not a eye tracking shader ... only thing i have is the albedo texture becomes invisible with the one i found through google

[lucid cedar]

Well it's pretty much the same thing

Orients the mesh towards the camera

You can do that with Vilar's eye tracking shader

[fluid hamlet]

Vilar’s never works for me even with follow at max the demo eyes stay in a single orientation and just do what the vrc realistic eyes plugin already does (except with iris dillation added)

[lucid cedar]

It works for me if I don't run the setup and fiddle with the settings some

So the follow ratio is 1 on the material

[safe heron]

https://booth.pm/ja/items/1084711

it's one of the few fur shaders that won't kill everyone's performance

[lucid cedar]

It still will, just not quite as much compared to others

Also depends on how high poly the mesh is

[sly coral]

anyone got the screenspace shader name. ive been googling for an hour and ive found nothing.

[sly coral]

or a different way to add a slight grey tinge to sorrundings

[ashen dagger]

accidently deleted my toon shaders, can someone link me to a good toon shader thats updated?

[lucid cedar]

Try Noenoe, XSToon, Silent's or poiyomi

[ashen dagger]

Alright ill take a look at xiexe thank youu~

[vocal wadi]

A bit late, but having multiple flat-lit-toon shaders in the same project can break it.
My avatars starded added outlines to themselves when I duplicated flat-lit-toon and made edits to it. In the end I had to remove the outline feature from both versions of the shader files

[past pewter]

copying and/or editing shaders to fit your preferences has no impact on anything and doesn't cause issues with people using the original one, thank god

[lucid cedar]

Flat Lit Toon just randomly bugs itself and creates those outlines

It's one reason why you should avoid using the non-Lite version

[lethal rock]

Bugs itself?
