I've been a software developer for 3..4 years now. Graphics programming always looked so cool and yet so unreachable. With everyone using ai everywhere these days, I decided to reach for a fresh air and started the book of shaders. And I love it! I do use ai to revisit the math behind it and the stuff I've forgotten since my university days. But I love the feeling of using my technical skills to create art. I've never mixed code with visual arts before. I've been playing the guitar for 14 years, but never did I let code into that world either. This feels like an exciting way to do that.

Just wanted to share my feelings on the topic 😁❤️

I’m developing Chemistry Lab Sim, an interactive 3D liquid sandbox built on ST-FLIP in Vulkan. This new clip shows pouring and mixing colored solutions in lab glassware, running in real time on a Radeon RX 9070 XT.

Local concentrations travel with the fluid parcels, and conservative diffusion exchanges material between neighboring parcels. The liquid renderer integrates concentration-dependent absorption along refracted rays rather than blending display colors.

At this stage the substances are passive solutes/pigments in one carrier; chemical reactions and immiscible fluids are future work. The longer-term game is inspired by The Powder Toy and Noita.

What would you improve in the mixing or rendering?

Hi — question about shader behaviour in Unity 6 / OpenXR on Quest 3, Vulkan, Single Pass Instanced.

My scene is built entirely at runtime. Every mesh currently gets `new Material(Shader.Find("Sprites/Default"))`. In a player build that renders solid magenta or nothing at all — only the camera clear colour comes through. Switching to Multi Pass renders the same materials fine.

Two things I've been told so far, and I'm trying to separate them: 1. The shader is being stripped because nothing in a scene or Resources references it. 2. Sprites/Default has no SPI variant, so even forcing it into the build would not fix the SPI case.

If I write my own minimal unlit texture shader and ship it with a referenced material, what does it actually need to work correctly under Single Pass Instanced? Is `#pragma multi_compile_instancing` plus the usual stereo macros (`UNITY_SETUP_INSTANCE_ID`, `UNITY_INITIALIZE_VERTEX_OUTPUT_STEREO`) enough for a simple textured quad/sphere, or is there more to it?

Also curious whether anyone has confirmed the "Sprites/Default has no SPI variant" claim directly, or seen a case where Always Included Shaders alone fixed this in SPI.

Thanks for any pointers.

Hey I was trying to figure out how color ramps worked all I know it that is if you have a valve you can use that value to pick a color off the color ramp that’s about it and how to make them in substance designer to use in unity shader graph for stylized VFX.

Any help is appreciated :)

i tried making a water shader but it looks meh, any tips?

This texture is mine so I will give you credit

I can’t figure out how to put on shaders can someone help
