RGB Explained: The MOST Important Concept Beginner Modders Skip

You’ve seen RGB values everywhere — in textures, materials, shaders… but do you really know what they mean?
If you want to understand how game materials actually work, this video is your perfect starting point!

In this tutorial, we break down RGB in a simple, visual way — and show how it affects diffuse textures, normal maps, specular maps, roughness maps, masks, vertex colors, and more. Once you understand the logic behind RGB, manipulating colors and building better materials becomes so much easier.

✨ What you’ll learn:
✅ What RGB really is — and why it works different from paint
✅ How 0–255 and 0–1 values relate (and how to convert them)
✅ What the alpha channel actually does
✅ Why specular, roughness and metallic maps store data, not color
✅ How normal maps use RGB to simulate tiny surface details
✅ What vertex colors are and where games secretly use RGB
✨ And at the end, you’ll explore a live demo of an RGB color picker to really understand how light mixing works!

Whether you're just starting with texturing or already creating your own assets, after this video you'll understand the foundation of every material in modern games — RGB. 🎮
