[Ice] Cracked Textures

Cracks in ice are internal, not surface features. A fracture inside a clear block is a thin sheet of air trapped between two ice faces, and it becomes visible only because light reflects off that interface — which is why cracks flash bright white from one angle and disappear entirely from another. Drawing them as dark lines on the surface produces the flat, etched look that gives most ice materials away. This collection covers internal fracture planes, surface crazing, shattered ice, and refrozen crack networks.

What's in this collection

• Internal fracture planes — flat reflective sheets suspended inside clear ice. Ice cubes, frozen lakes, hero props.
• Surface crazing — fine networks of shallow cracks across a frozen surface. Windows, puddles, frozen ponds.
• Shattered ice — broken plates with sharp edges and displaced fragments. Impact effects, breaking ice sheets, VFX.
• Refrozen networks — old cracks healed with cloudy bubble-filled ice. Lake ice, sea ice, long-frozen surfaces.

All tiles are seamless in both directions and delivered at high resolution.

Where cracked ice is used

Game environments. Frozen lakes, ice caves, and winter levels. Cracked ice is also a standard gameplay signal for a surface that is about to give way, so its readability matters mechanically as well as visually.

VFX and motion graphics. Freeze and shatter effects, impact transitions, and title treatments.

Product visualization. Beverage advertising, where ice cubes carry a large share of the image and are examined closely.

Film and documentary work. Winter exteriors, polar sequences, and set extensions on frozen locations.

How to use these in Blender

1. Build the base as a Principled BSDF with Transmission at 1 and IOR around 1.31.
2. Use the crack texture to drive Roughness and a slight white mix into Base Color, so fractures scatter light instead of reading as painted lines.
3. For hero ice, model the fracture planes as actual internal geometry with a thin transmissive material — nothing else reproduces the angle-dependent flash.
4. Add a Volume Scatter at low density for the cloudy bubble zones that surround old cracks.

How to use these in Unreal Engine 5

1. Import the texture and build a translucent Material with refraction, feeding the crack map into both Roughness and an emissive-tinted scatter term.
2. Use a parallax or depth offset on the crack layer so fractures appear to sit below the surface rather than on it.
3. Drive crack intensity from a material parameter to animate ice breaking under a character or vehicle.
4. Keep the surface itself smooth. Cracks are internal, so the outer face should stay glossy even where the fracture network is dense.

How to use these in Unity

1. Drop the texture into your project's Assets folder.
2. Use a transparent or refractive shader with the crack texture modulating smoothness rather than albedo.
3. Assign a normal map only for surface crazing, not for internal fractures, which have no surface relief at all.
4. Add a reflection probe so the fracture planes have an environment to catch.

Tips for cracked ice specifically

Cracks are bright, not dark. The instinct to darken a fracture comes from drawing conventions, but a real internal crack is a mirror. Under most lighting it appears lighter than the ice around it.

Fractures are planar. Ice breaks along flat surfaces, so cracks appear as straight lines from one angle and vanish edge-on from another. Curved, organic crack shapes look like a different material entirely.

Depth needs parallax. If the crack layer moves exactly with the surface as the camera shifts, the ice reads as a printed sheet. Even a small parallax offset places the fracture convincingly inside the volume.
