High-Quality Grass Texture Generator [Image Generation]

This page is a high-performance simulation tool that instantly generates textures for plants, grass, and natural environments right in your browser. The processing is designed to be lightweight for image generation. Use it for web design backgrounds, 3D modeling textures, or pure visual simulations. You can select from a wide variety of grass patterns (turf) and make detailed numerical edits. Custom color changes are also possible.

Density 3000

Controls the number of grass blades per unit area. Higher values make the ground less visible and create a richer texture, but slightly increase rendering load. 3000 is a well-balanced standard value.

Grass Height 60

Sets the average height of the grass in px units. For turf, 20-40; for wild grass, 60-100; for tropical plants, 150 or more is a guideline.

Grass Width 6

Sets the width at the base of the grass. Thinner gives a delicate and soft impression, thicker suits strong succulents or cartoon-style expressions.

Base Color Selection

Custom:

The overall base color. Choose from a curated palette of 35 natural colors or specify any color with the color picker.

Hue Variation 30

Expands the color difference (hue range) for each blade of grass. Larger values mix in colorful shades like autumn leaves or flower fields.

Dead Grass Mix Rate 5

Randomly mixes in brown discolored dead grass. Mixing in about 5% eliminates the artificial feel unique to CG and dramatically improves realism.

Curve Strength 40

The degree to which grass droops due to gravity. 0 for upright, higher values make it soft and drooping.

Chaos/Disorder 30

Randomness in growth direction. Higher values express the ruggedness of untamed wilderness.

Ground Noise 50

Controls the soil texture visible through gaps in the grass. Higher values strengthen the grainy feel of the soil.

Wind Strength/Direction 0

Makes the whole sway in one direction. Negative for left wind, positive for right wind. Ideal for staging dynamic scenes.

Basic Operation Guide & Tips

This section explains the basic flow of texture generation. By selecting a "preset" close to your purpose from the left menu, the base environment is built instantly. Then, use the "color palette" on the right to change the overall tone, or fine-tune with sliders for "density" or "height". The "seamless button" is especially important; turning it ON generates the image with top-bottom and left-right connections, making it ready to use as tiling material for 3D models or web backgrounds. This tool uses proprietary "sprite cache" technology to store once-calculated grass shapes in memory and quickly place them like stamps during redrawing, allowing instant previews of tens of thousands of blades.

Expert Features Explanation

The tab menu above includes advanced parameters for those seeking more detailed settings. "Dead grass mix rate" is key to realism; including a few percent of brown mimics the imperfections of nature better than perfectly uniform green. "Wind strength" gives a dynamic impression by making all grass sway in a specific direction, even in a still image. Also, adjusting "shadow density" can create depth with ambient occlusion-like three-dimensionality.

Usage Tips and Advice

The generated textures excel not just as still images but in various creative scenes. For example, images exported with "seamless" settings can be infinitely tiled as ground materials in 3D software like Blender or Unity. Also, overlaying them as "overlay" or "multiply" layers in image editing software like Photoshop adds organic noise and texture to existing photos or illustrations. Setting low resolution works as a base for retro game-style pixel art materials. This tool's algorithm adopts random functions conscious of nature's "1/f fluctuation," achieving pleasant irregularity without being too artificial.

Summary and Notes

This generator is designed to realize the creation of grass pattern images as you envision. Experiment with near-infinite variations to find your ideal "green." Generated images can be used widely from personal hobbies to commercial projects, but all use is at your own responsibility. The site and developers assume no responsibility for any damage or trouble arising from the use of generated items. Also, please refrain from reselling the program code itself or unauthorized reproduction of scripts. Depending on your device's specs, generation at maximum size and density may momentarily slow down.
