TerraPaint is an extensive asset library containing over 500 stylized terrain models and 60 rock assets designed specifically for background and mid-ground scene composition. The collection covers multiple biomes, including snowy mountains, grasslands, deserts, and lava fields. Alongside the 3D meshes, the package includes an EEVEE-exclusive geometry node setup for generating distant stylized forests, atmospheric fog shaders, and hand-painted cloud textures. Designed for building vast environments quickly, these assets are intended for distant shots and are not optimized for close-up renders or real-time game engines. Six complete example projects with associated PSD files are provided to demonstrate assembly techniques.
