BiteTheBytes has released version 2026.4 of World Creator, its GPU-based terrain generator. The update includes support for mathematical expressions in numeric fields, normal blending, and full decals. Additionally, there is a new free community edition so anyone can play with mountains and rivers without spending a euro.
Mathematical expressions and vectors to tame geological chaos 🏔️
The standout new feature is the integration of mathematical expressions in numeric fields, allowing artists to define terrains with equations instead of simple sliders. This is combined with normal blending to seamlessly mix terrain layers. Decal support is now complete, and the generation of linear shapes like roads or rivers follows vector paths with precision. Everything works with procedural and manual workflows, using layers and basic 3D sculpting.
Now you can justify your mountain with a blackboard equation 🧮
If before you created a valley by moving a slider and hoping for the best, now you can write a mathematical function so the terrain behaves as you command. Or as the function decides, which is sometimes the same thing. The best part is, if someone asks why your mountain range is shaped like a spiral, you can respond with a straight face that it's an analytical solution. And if it fails, you can always blame the GPU.
