Question Custom Particles-compatible shader?

Hey, so the default Particles > Standard Unlit shader has the limitation of not being able to determine Render Queue properties.

I'm following this tutorial for a portal shader system, but at the particles stage it uses a basic unlit shader, which is not compatible with the color properties in the Particle System settings. So even when I have this set:

It still shows as white:


I may be barking up the wrong tree, because maybe there's a simple setting I can enable this functionality with in the shader, but I can't seem to find it. The system default Particles Unlit shader has a lot of settings for colors and I have no hope of pinpointing what about it enables it to take on Particle System color influences.

Can anyone please point me in the right direction to make this work?

 

Hm, that doesn't seem to work. Adding it to a copy of the shader, it throws the error:

Parse error: syntax error, unexpected TOK_MATERIAL, expecting TVAL_ID or TVAL_VARREF

 

So for clarity, what I did is I made a copy of Unity's default ParticlesUnlit.shader file, hoping to capture the particle system compatibility and to add the capacity to modify the Render Queue order beyond 50 (The ParticlesUnlit shader has a default range of -50 to 50).

I tried adding the line of code you suggested to both the Properties and Subshader subheadings in turn:

Properties:

Code (CSharp):

1. Shader "Universal Render Pipeline/Particles/UnlitNew"
2. {
3.     Properties
4.     {
5.         [MainTexture] _BaseMap("Base Map", 2D) = "white" {}
6.         [MainColor] _BaseColor("Base Color", Color) = (1,1,1,1)
7.         _Cutoff("Alpha Cutoff", Range(0.0, 1.0)) = 0.5
8.         _BumpMap("Normal Map", 2D) = "bump" {}
9.         [HDR] _EmissionColor("Color", Color) = (0,0,0)
10.         _EmissionMap("Emission", 2D) = "white" {}
11.         material.renderQueue = yourNumber;

This is the one that threw the error I described:


Subshader (where queue order seems to be assigned):

Code (CSharp):

1.     SubShader
2.     {
3.         Tags{"RenderType" = "Opaque" "IgnoreProjector" = "True" "PreviewType" = "Plane" "PerformanceChecks" = "False" "RenderPipeline" = "UniversalPipeline"}
4.         material.renderQueue = "Geometry-2";
5.  

This actually changes/unlocks the render queue options for the shader, but they're broken and the material changes to the broken default Pink:


Also it seems changing the Render Queue order doesn't actually affect the render order, but the whole shader is broken in this scenario so I can't speak to what might be causing that.

 

Like as an addable component to the material itself?

Where in a new C# script would I put that?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ColorParticles : MonoBehaviour
6. {
7.     // Start is called before the first frame update
8.     void Start()
9.     {
10.        
11.     }
12.  
13.     // Update is called once per frame
14.     void Update()
15.     {
16.        
17.     }
18. }
19.
