URP Renderer Feature to force a CopyDepth pass (Unity 2022.2, URP)
View CopyDepthFeature.cs
/*
Afaik in Unity 2022.2,
If URP uses a Depth Prepass :
- The depth texture will only contain opaque objects, based on the Default Opaque Layer Mask
at the top of the Universal Renderer asset.
- So if you remove a layer from that and instead render it with RenderObjects features,
those objects no longer appear in the depth texture, even if their shader is writing depth :(
- Same goes for any Transparent objects with ZWrite On. The depth texture won't include those

PropertyAttribute/Drawer used to auto-filter ObjectPicker window (showing assets / scene references) by name - Unity, IMGUI
View ExampleUsage.cs
// Example usage in some other script
[FilterObjectPicker("Projectile")]
public GameObject projectilePrefab;
// When clicking object field in inspector, would only see gameobjects with "Projectile" in name.
// Can remove filter text at top of object picker to see all gameobjects again.
// To allow scene references, add second param as true. e.g. :
[FilterObjectPicker("Test", true)]

Setup _CameraOpaqueTexture (for Scene Color node) in Unity's Built-in Render Pipeline (BiRP)
View SceneColorSetup.cs
/*
Copies the camera buffer after rendering opaques, to _CameraOpaqueTexture property so the Scene Color node can work in the Built-in RP.
Attach this script to the Main Camera (and any other cameras you want an Opaque Texture for)
Will also work for Scene Views (Though if a new window is opened will need to enter & exit play mode)
Tested in 2022.2

Some custom commands for the YAGPDB discord bot.
View customCommands.md

Wrote these YAGPDB discord bot custom commands for Harry Alisavakis' discord (Technically Speaking), but maybe others will find it useful so sharing them here ~ Enjoy!

In the server we have a channel where users can suggest themes for upcoming tech art challenges, and others can react (first emoji only) to vote for it. These commands assist with keeping track of these themes and votes.

Users use a -suggestTheme <theme> command. Then when reactions are made (or if -updateThemes is used) a message, posted by the bot previously during setup, is updated with an embed listing the themes, sorted by no. of votes. That message is pinned for easy access.

URP Render Feature that manually renders DepthOnly pass to _CameraDepthTexture, filtered by LayerMask. Tested in URP v10, Unity 2020.3
View RenderToDepthTexture.cs
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Rendering.Universal;
/*
- Renders DepthOnly pass to _CameraDepthTexture, filtered by LayerMask
- If the depth texture is generated via a Depth Prepass, URP uses the Opaque Layer Mask at the top of the Forward/Universal Renderer asset
to determine which objects should be rendered to the depth texture. This feature can be used to render objects on *other layers* into the depth texture as well.
