Lava fields, crater rows and frozen lakes of Iceland - 30 real-world winter maps for Unity

Rough lava plains broken by pressure ridges, fissures and crater rows, the Hverfjall tuff ring above its lake shore, and lake basins between low volcanic hills. Elevation data (DEM) at 2.46 m per pixel keeps the fine forms of the lava: one height level is only 6.6 to 31.6 mm. Each map covers 20 x 20 km (400 km²) with 215 m to 1,034 m of relief.

✦ CONTENTS

• 30 heightmaps of lava country - 16-bit PNG, 8129 x 8129 px, size and height range in the file name
• Terrains at true scale - 2 x 2 Unity terrains of 4097 samples per map from the original pixels, lowest point at Y = 0
• Three demo levels - Hverfjall Tuff Ring, Frozen Lake and Ridges and Lava Lake Field in Built-in, URP and HDRP
• Frozen lakes - found in the terrain by the painter and painted as snow-swept lake ice - no water planes to manage

​

✦ LAVA UNDER THIN SNOW

• Eight 4K layers - packed snow, drift snow, wind crust, thin snow over lava, basalt, talus, tuff and ice
• Black tops through the snow - rough lava keeps only a thin cover; the hollows behind each ridge hold deep drifts
• Tuff rings and crater rims - ochre tuff where the slopes are too steep for snow
• Your own terrains too - Paint Selected Terrains lays the same winter ground on any terrain; Build and Paint does it from a PNG

​

✦ SPEED

• Native 3840 x 2160 on an RTX 3090 - HDRP 120-156 FPS · URP 150-170 FPS · Built-in 299-339 FPS, no upscaling

​

✦ COMPATIBILITY

Unity 2022.3 and above; Built-in, URP and HDRP. One click in Project Setup switches on the terrain holes the builder uses. In Built-in the demo levels run without post-processing and look plainer.

​

✦ WHERE IT FITS

Volcanic survival games, rally and off-road driving, exploration games, sci-fi planet surfaces and cold-climate simulation.
