Key technical topics include: color-based entity picking (rendering entities with unique colors to an offscreen buffer to detect mouse-over), a watering can item with a water meter UI, a well entity for refilling, and terrain tile wetness rendering. The developer switched soil tiles from a single mesh to instanced rendering to allow per-tile color changes, added a wetness value (0–1) per tile that blends between dry and wet colors, implemented gradual drying over time, and used a shader-based weighted average of neighboring tile wetness values to smooth color transitions between tiles. ## Full article daily.dev links to this article rather than hosting it.
