Hi all,
I'm trying to create a edge detection/outline shader based on [this guide][1]. While working on it I ran into issues getting the normal data through the method specified in the guide (rendering to a second camera) because our project is using the high definition render pipeline and is deferred. To get around this, I learned I could sample the _NormalBufferTexture instead to get a packed version of the normal buffer, which I've been able to output to the screen.
![alt text][2]
The issue is, in order to access the function I need to unpack the normal buffer (DecodeFromNormalBuffer I believe) I need to include
"com.unity.render-pipelines.high-definition/Runtime/Material/NormalBuffer.hlsl"
in the shader. When I do this though, it spits out this error:
"unrecognized identifier 'real3' at com.unity.render-pipelines.core@4.6.0-preview/ShaderLibrary/Packing.hlsl"
This is most likely due to me not having the
"Common.hlsl"
include, but whenever I do include that file it seems to conflict with the "StdLib.hlsl"
include from the post processing package because it spits out a bunch of 'redefinition' errors and warnings for functions and macros that I assume are shared by both files.
I've tried a lot of things like reordering my include calls, renaming and deleting things in the Package files, and directly creating the functions in the shader but these attempts have either created more errors or just not worked at all.
I was wondering if anyone else may know how to solve this issue, or if there are any ways I can do the unpacking without any additional includes.
Thanks!

How to create outlined particles or sprites?
Hi everyone,
I'm trying to make some blob like think for 2D.
My plan is to place sprites(or particles using sprites if possible) like below and use some shader to only show non-overlapping edges.
Example: from this ![alt text][1] to this ![alt text][2]
I believe using shaders can achieve what I want to do but I am no expert in shader stuff and completely lost :( I would really appreciate if one can enlighten me where I can begin with. [1]: /storage/temp/136460-스크린샷-2019-04-15-오후-71046.png [2]: /storage/temp/136459-스크린샷-2019-04-15-오후-71029.png

What is the best way I could recolor all the pixels of a certain country on a texture of a political map(for achieving a map mode system such as in a grand strategy game)?
I'm using a texture of a political map where all the countries are painted with a unique color. I can assign data and know what the pointer is clicking/hovering over.
So an example of an overlay would be:
Germany is color coded gray and has a high GDP. The shader draws dark blue where all the gray colored pixels are in the texture to show a high average GDP in the area of Germany.
Moldova is color coded green and has a low GDP. The shader draws light blue where all the green colored pixels are in the texture to show a low average GDP in the area of Moldova.
The darkness of the blue is determined by a dynamic GDP value from the data of a country.
It would be very preferable if the texture of the map remains in 1 piece due to the normal map(hills and depressions)
An answer to this would be to have a conditional in the shader per color of the color coded countries, but it would be extremely slow.
Another answer would be to somehow flood fill all the countries and recolor them in order to create a new texture, but it would also be slow.
Looking to achieve such an effect as demonstrated in this video about Crusader Kings 2 map modes https://www.youtube.com/watch?v=hllUdi73h70

What basic shader is needed for change the color on particle system with particles based on a spritesheet?
Hi
I have a particle system loaded with a material what have loaded a spritesheet. As far as i know that is the only way for having a spritesheet working on a particle system.
My problem is that if i try to activate color parameters,nothing happens with Unlit/Transparent shader.
Changing shader for Legacy/Particles/Additive make it's works, but particles are semi-transparent and i want them on full opacity.
Do you know what shader i need? I think this is something very simple and doesn't requiere complex custom shaders...

MK Glow only works in Scene View
Hi, I just imported MK Glow and opened the example scene and ran.
![alt text][1]
in this picture, left side is the Scene view, and the right side is the Game view.
However, I don't see any of the glowing effect like I would see in the Scene view.
Just in case I did something wrong, I followed this tutorial https://www.youtube.com/watch?v=9Ztd1XXmUGI, and made my own shape to glow, but it has exactly the same problem with the example scene.
![alt text][2]
As you can see, left side (Scene view) has the glow on the circle, but the right side (Game view) has zero glow. If I adjust the minimum value of the Threshhold from MK Glow script to below zero, everything in the camera starts to glow, which I don't want.
What am I doing wrong?

How do I adapt this vertex manipulation shader so that my object (point cloud) keeps its original colouring?
Hello!
(Photos attached below might help to better explain)
I am currently attempting to use *this* vertex manipulation shader on a point cloud object:
Shader "Tutorial/015_vertex_manipulation" {
//show values to edit in inspector
Properties {
_Color ("Tint", Color) = (0, 0, 0, 1)
_MainTex ("Texture", 2D) = "white" {}
_Smoothness ("Smoothness", Range(0, 1)) = 0
_Metallic ("Metalness", Range(0, 1)) = 0
[HDR] _Emission ("Emission", color) = (0,0,0)
_Amplitude ("Wave Size", Range(0,1)) = 0.4
_Frequency ("Wave Freqency", Range(1, 8)) = 2
_AnimationSpeed ("Animation Speed", Range(0,5)) = 1
}
SubShader {
//the material is completely non-transparent and is rendered at the same time as the other opaque geometry
Tags{ "RenderType"="Opaque" "Queue"="Geometry"}
CGPROGRAM
//the shader is a surface shader, meaning that it will be extended by unity in the background
//to have fancy lighting and other features
//our surface shader function is called surf and we use our custom lighting model
//fullforwardshadows makes sure unity adds the shadow passes the shader might need
//vertex:vert makes the shader use vert as a vertex shader function
//addshadows tells the surface shader to generate a new shadow pass based on out vertex shader
#pragma surface surf Standard fullforwardshadows vertex:vert addshadow
#pragma target 3.0
sampler2D _MainTex;
fixed4 _Color;
half _Smoothness;
half _Metallic;
half3 _Emission;
float _Amplitude;
float _Frequency;
float _AnimationSpeed;
//input struct which is automatically filled by unity
struct Input {
float2 uv_MainTex;
};
void vert(inout appdata_full data){
float4 modifiedPos = data.vertex;
modifiedPos.y += sin(data.vertex.x * _Frequency + _Time.y * _AnimationSpeed) * _Amplitude;
float3 posPlusTangent = data.vertex + data.tangent * 0.01;
posPlusTangent.y += sin(posPlusTangent.x * _Frequency + _Time.y * _AnimationSpeed) * _Amplitude;
float3 bitangent = cross(data.normal, data.tangent);
float3 posPlusBitangent = data.vertex + bitangent * 0.01;
posPlusBitangent.y += sin(posPlusBitangent.x * _Frequency + _Time.y * _AnimationSpeed) * _Amplitude;
float3 modifiedTangent = posPlusTangent - modifiedPos;
float3 modifiedBitangent = posPlusBitangent - modifiedPos;
float3 modifiedNormal = cross(modifiedTangent, modifiedBitangent);
data.normal = normalize(modifiedNormal);
data.vertex = modifiedPos;
}
//the surface shader function which sets parameters the lighting function then uses
void surf (Input i, inout SurfaceOutputStandard o) {
//sample and tint albedo texture
fixed4 col = tex2D(_MainTex, i.uv_MainTex);
col *= _Color;
o.Albedo = col.rgb;
//just apply the values for metalness, smoothness and emission
o.Metallic = _Metallic;
o.Smoothness = _Smoothness;
o.Emission = _Emission;
}
ENDCG
}
FallBack "Standard"
}
This successfully creates the wave-like effect on the object i wanted. However, the problem is that when I do this it replaces the vertexcolor shader on the point cloud and so the point cloud goes black and no longer retains its original colouring.
This is the code for the vertexcolor shader:
Shader "Custom/VertexColor" {
SubShader {
Pass {
LOD 200
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
struct VertexInput {
float4 v : POSITION;
float4 color: COLOR;
};
struct VertexOutput {
float4 pos : SV_POSITION;
float4 col : COLOR;
};
VertexOutput vert(VertexInput v) {
VertexOutput o;
o.pos = UnityObjectToClipPos(v.v);
o.col = v.color;
return o;
}
float4 frag(VertexOutput o) : COLOR {
return o.col;
}
ENDCG
}
}
}
Is there any way I can adapt the vertexmanipulation shader so that the point cloud retains its original colouring (like it does with the vertexcolour shader) whilst still creating the wave-like effect I wanted?
I hope this makes sense - I’m sorry I’m relatively new to shader coding in unity. Below I have attached a couple of screenshots which might make it clearer.
Any help would be massively appreciated!
Many thanks in advance,
Tom

This is the point cloud with the vertexcolor shader - when you can see its colouring.

And this is the point cloud with the vertex manipulation shader - it creates the wave-effect I want but makes the point cloud completely black.

How to choose FFT Window type
Hi. I noticed there are this types on the FFTwindow function from Unity
**Rectangular** W[n] = 1.0.
**Triangle** W[n] = TRI(2n/N).
**Hamming** W[n] = 0.54 - (0.46 * COS(n/N) ).
**Hanning** W[n] = 0.5 * (1.0 - COS(n/N) ).
**Blackman** W[n] = 0.42 - (0.5 * COS(n/N) ) + (0.08 * COS(2.0 * n/N) ).
**BlackmanHarris** W[n] = 0.35875 - (0.48829 * COS(1.0 * n/N)) + (0.14128 * COS(2.0 * n/N)) - (0.01168 * COS(3.0 * n/N)).
How do I know which one is the best to use in my case and why? I did some research but it still not very clear to me, they all seem to be ok to use in different situations. If anyone know a good article or something about this topic would be very useful too!

creating shader to highlight overlap of objects in screen spcae
How can I make a shader that highlights the intersection of objects in SCREEN space (NOT world space)? Basically I want to be able to find the areas that overlap and then alter the appearance of those areas. Below is a very crude example of what I want. Ideally the solution would be able to account for an arbitrary number of overlaps. From what I've read it seems I would need to use stencil shaders but I have a hard time understanding how those work and how I would apply them.
Any help would be appreciated. If there is an already existing solution then that would be great too.
EDIT: I think I've figured out the general idea for the stencil shader, but I'm wondering if there is a way to get the output data from the first pass of the materials to for additional computation in the second pass. I.e. is there a way that I can see that the color of two overlapping boxes were red and blue, and add those colors together in the second box.

How to create color balance shader?
Hi guys. I have been trying to implement my own color balance that i will apply on camera, For that i used this formula:
**R** = 255 / ***Rw*** * R1
**G** = 255 / ***Gw*** * G1
**B** = 255 / ***Bw*** * B1
Where ***Rw Gw*** and ***Bw*** represents the value of a colour component believed to represent White and *R1 G1* and *B1* representing the original value of a colour component before implementing the colour balance formula.
I tried to implement it like this:
public class ColorBalance : MonoBehaviour
{
[Range(0,255)]
public int R = 0;
[Range(0, 255)]
public int G = 0;
[Range(0, 255)]
public int B = 0;
[Range(0, 255)]
public int Alpha = 255;
public Material material;
private void OnRenderImage(RenderTexture source, RenderTexture destination)
{
material.SetVector("_RGB", new Vector4(255f/R, 255f/G ,255f/ B, 255f/Alpha));
Graphics.Blit(source, destination, material);
}
}
Where material had shader like this:
Shader "PostProcessing/ColorBalance"
{

{
_MainTex ("Texture", 2D) = "white" {}
_RGB("_RGB", Float) = (0.01,0.01,0.01, 1)

For a clearer explanation, take a look at this image ![alt text][1]
those black parts are actually transparent from photoshop saved as PNG.
Is it the shader's fault, or is there anything I should tweak on unity to make it accept alpha as transparency?

Oculus rendeing bug
Good day!
In there is a problem when rendering the Oculus.
1 screen - render camera in normal game.
2 screen - render camera with Oculus.
The problem is trees sprite. In Oculus has no sprites of foliage. I think the Shader's broken.
How can this be fixed?
Trees from SpeedTree. It was once that they had drawn, but was green (again, I think that something with the Shader)

Migrating from 2018.3.x to 2019.1
After upgrading from 2018.3.x to 2019.1 nearly all of my shaders broke, prefabs were removed from my scenes, I was spammed with nearly 200 errors from the Shader Graph (which I didn't have installed) and Text Mesh Pro v2.0.0 (which I did have installed, but says it's 2019.1 verified in the package manager) I tried several different things but none worked. I eventually created a new project and moved my Assets over which solved the Shader Graph issue, but is still causing the same problems with Text Mesh Pro. Additionally, the [2019.1 upgrade guide](https://docs.unity3d.com/Manual/UpgradeGuide20191.html) provides essentially no information. Did I do something wrong? Are these bugs in the release?
