⚡ Last month before the price increase! ⚡
➜ NEW: WATER! We’ve added a stylized water shader to Flat Kit!
The water shader (available only in URP) has more than 30 parameters, making it super versatile. Yet it’s simple to tune and includes 3 full example scenes, multiple meshes and lots of ready-to-use presets.
The custom shading model is versatile enough to work great for classic cel/toon shading and for unique styles of experimental projects.
