This meetup is a beginner-friendly, hands-on workshop focused on building shaders in Unity using Shader Graph. Instead of slides or theory-heavy lectures, we'll build real shaders together step-by-step. The format is structured but interactive. You'll watch a quick demo, then build each shader yourself with guidance. By the end, you'll have created multiple shaders you can immediately use in your own projects—and understand how to make more. **What to Expect:** * Build 4–5 complete shaders from scratch * Color tints, snow accumulation, scrolling water, dissolve effects, and more * No prior shader experience required * Checkpoint files provided if you fall behind * Resources for continued learning All experience levels are welcome. Whether you've never opened Shader Graph or just want to fill gaps in your knowledge, this is a supportive space to learn by doing. **Food and drinks provided. Join us to learn, build, and level up your shader skills.** I added the Unity project to the repo here - https://github.com/EricJRico/IntroToShaders.git This is what we'll be using for the session.
