Low Poly Cloud 3D Model

A tiny decorative cloud mesh can be 60 to 180 triangles, built from a few faceted lobes. A midground floating cloud for a mobile or WebGL scene usually sits between 250 and 800 triangles, while a close fly-through cloud bank on desktop can use 1,500 to 4,000 triangles per cluster if it is broken into LODs. For a distant sky, do not model every cloud: use flat billboard cards or a skybox texture, because a cloud that never receives player interaction does not need three-dimensional volume.

Clouds have a special pivot requirement. Put the object origin at the visual center of mass rather than the bottom, because clouds are positioned in 3D space, animated along wind paths and often rotated around their centers for subtle drift. If the cloud is made from separate lobes, keep their transforms applied after arranging the puff cluster so the combined bounding box stays stable for culling. Bad bounds are a common reason clouds pop out of view at screen edges.

The non-obvious rendering issue is transparency sorting. Many stylized clouds are tempting to build as semi-transparent planes, but alpha blending sorts poorly when cards overlap and can create flickering halos in WebGL. A solid low poly cloud mesh with flat white and blue-grey materials often looks cleaner and renders in the opaque pass. If you must use billboard clouds, prefer alpha-tested edges over heavy alpha blending, and keep them in a dedicated sky layer so they never intersect gameplay geometry.

Lighting should be simple and consistent. Use one bright top material, one side material and one cooler underside material rather than relying on real-time shadows from every cloud lobe. Real-time cloud shadows are expensive and often noisy in stylized scenes; if the design needs moving shadows, project a simple transparent blob or use a shader mask on the ground instead of enabling shadow casting on every cloud mesh.

Low poly clouds fit sky islands, cozy farm scenes, racing horizons, AR weather toys and WebGL hero backgrounds. Export GLB for browser and Godot scenes, FBX for Unity and Unreal sky layers, or use generated cloud meshes as source assets for a baked skybox.
