Renders Unlit Opaque objects into CameraNormalsTexture for SSAO Depth Normals mode
/*
Render Unlit Opaque objects into CameraNormalsTexture for SSAO Depth Normals mode.
If you need Alpha clipping or vertex displacement, you'll need to use Depth mode,
or edit the generated shader code to add in the DepthNormals pass instead.
This is meant as an alternative if you don't need those.
For depthNormalsMat, I'm using a blank PBR/Lit SG with passIndex set to 4 (corresponds to it's DepthNormals pass).

Cyanilux / SGTessellation.hlsl
Last active April 30, 2021 22:13
Allows you to inject tessellation into SG & URP, but hacky / can be difficult to work with. Unsure if the same method can work for HDRP. Also see : https://twitter.com/Cyanilux/status/1388158860574314498. Tested in v10. Could definitely break at some point, use at your own risk :)

While this works, it's maybe not as useful as you might think. I believe any vertex displacement would need to be
taken out of the graph and moved into the domain function below (since tessellation still runs after vertex shader).
I thought about using the VertexDescriptionFunction from the generated code, but sadly that's generated after the injection point
so can't be called as it's undeclared at that point.

Experiments with DrawMeshInstanced and DrawMeshInstancedIndirect for drawing grass (over terrain)
// https://twitter.com/Cyanilux/status/1396848736022802435
// Requires a specific shader to read the _PerInstanceData buffer at SV_InstanceID
// I use a shader made in Shader Graph, See : https://gist.github.com/Cyanilux/4046e7bf3725b8f64761bf6cf54a16eb
// Also note, there's no frustum culling involved in this example. Typically a compute shader is used for this.

Fog of war example using Graphics.Blit. But probably not very optimised.

public RenderTexture rt; // Render Texture asset, combines rt_units with rt from previous frame

Cyanilux / RenderToDepthTexture.cs
Last active March 14, 2024 16:07
URP Render Feature that manually renders DepthOnly pass to _CameraDepthTexture, filtered by LayerMask. Tested in URP v10, Unity 2020.3
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.

Some custom commands for the YAGPDB discord bot.

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.
