It's been quite a few months now with little to no updates. I'm sorry about that.
It's a combination of things, none of them individually overwhelming but all of them adding up to my inability to create new content.
I started this patreon as a way to help me fund and create my own game, with the idea being that I ...

A small and simple little tweak to custom lighting on a shader. It ignores the normals near to the light source to create a soft bleed-through effect, like a directionless subsurface scattering.
There's also a slightly hu...

Here's an easy way to make an interactive waterfall, by rendering particles to a render texture via an orthographic projection that's aligned with the waterfall surface. These particles define the negative space part of the waterfall - the gaps created by the objects blocking the water.
It uses very bas...

Here's a little script and some shader functions that let you write out an object's transformation matrix and then read it as a Signed Distance Field (SDF) in a shader.
I've included 3 SDFs, a basic sphere, a rounded box with adjustable roundness, and a capsule. They can be freely moved, rotated and scaled.

This is pretty much the same as the previous Environment Interaction asset, now cleaned up, a bit easier to use, and updated with a few extra things that I've added in since I made the original.
The main visible addition is the grass swaying on the ground trail. The trail now wobbles between and outward push an...

Repurposing the Environmental Interaction render texture camera to create a Fog of War effect.
The G channel is "full fog" (unexplored areas), and the R channel is "semi fog" (explored, but currently unobserved areas). You can mark areas as covered by the fog using the special Fog of War Quads that exist in the FogO...

The in-built Particle Ribbons are pretty limited to create this effect, and a few workarounds have to be done to get it functional, but it works well enough for a quick one-off. To take it further I'd want to generate my own mesh, to allow the ribbon to split into multiple ribbons when the points are too far apart, to interpo...

A simple way to make particles spawn on a weapon and leave a trail behind, plus a few fun particle shader variations for magic weapons - because sharp steel isn't deadly enough, it has to do elemental damage as well.
We want the weapon to leave a trail of particles behind when it's moved. But since you'd normally put th...

Here's a fun little bubble popping shader that works on particles. Good for mud, lava, or other bubble forming liquids.
The bubble popping part is all done with opacity clip and vertex offset - I've made a quick toon-lite version as an example, but you can create your own colour variations depending on the bubble materi...

Hello!
The type of content Iβll be producing for patreon will likely change over the next few months, from almost entirely (100%) shaders and effects, to other game assets, such as 3d models, textures and perhaps some animations too. Still with a focus on non-photorealistic and stylised aesthetics. Iβ...

I thought it would be a good idea to explore a few more simple variations of the mesh lights from the previous post. These ones don't use N.L light direction, so they're more like volume projection than a different way to do lighting. I've put them all on a rounded cube volume for these examples, but you can just swap that ou...

I've added some basic texture projection into the fake mesh light shader. It can now project a cubemap texture or 2d texture spherically around it. The 2d mapping will need tweaking if you need it to visually match the emitter sphere, depending on how you've uv mapped that.

I've been wanting to make this one for a while - instead of using point lights, this shader fakes it with a billboard quad and calculates all the lighting manually using the Normals and Depth information in the _CameraDepthNormalsTexture render texture. You'll need to make sure your camera is rendering this D...

I'm back after a short break in which I focused on health and family and all things that aren't shaders. So I'm easing back into it with a smudgy depth-based pixelization shader I've been wanting to make for a while.
It blends between 3 levels of pixelization so objects closer to you are more 'in focus' and objects furt...

Here's a way to fake the rendering of a lit sphere on a quad. Currently all the sphere calculations are done using Maths (generating world normals and spherical depth from the quad UVs), but I'd like to do some tests to see if it might be more performant to bake the normals and depth and use a texture sample instead.

Here are a few variations on the blobby polygon compositing shader I've been playing with. In the original version of this effect, I blurred the normals and then injected that back into the render stack, which only works in deferred rendering.
In these versions I'm instead writing out the blurred pass to a rend...

Here is a way to make blobby liquids and smoke from simple geometry (sphere in this case) by messing with the gbuffer (blurring the normals) and then compositing it back to the main camera with a depth comparison.

A very simple example of how you can adjust shader properties via UI events via script.

Here's a simple Toon Eye shader with some nifty eye related features. The pupil and iris centre is pushed back via parallax, and the specular reflection is a static matcap, so it always glints in the same place. This is not at all realistic, but gives a more controllable toony effect.
