This collection contains different gravel textures and – as an industry first – gravel as real 3D geometry. Along with the included stone textures, this opens up a near-endless variety of different gravel styles.
Next to 3D people and vegetation, rendering realistic gravel is qrroway of the last remaining challenges when it comes to architectural visualization. Most 3D artists try to avoid graveled surfaces wherever possible.
But gravel is a very important building material and cannot always be avoided – nor should it be. Its role in architecture, landscaping and even interior design will let this challenge persist. Fortunately, technology has now caught up with the problem. With this texture collection we are attempting to close this particular gap between the imagination of the client and what you as a 3D artist can deliver. This product contains a total of gravel textures, based on 15 different gravel styles.
Each texture consists of diffuse, bump, normal, displacement and reflectivity maps, arrway well as a number of special maps that will help you to modify the gravel textures or to create entirely new textures. As a first on the market, we offer gravel ‘textures’ in form of real 3D geometry. All meshes are provided in. Meant to be used with the 3D gravel meshes, this product also contains especially optimized stone textures in different styles and colors, based stoen 94 distinct sets.
Each texture set consists of diffuse, bump, normal, as well as reflectivity arorway. This product contains different gravel textures, which were created based on 15 different gravel types and styles.
Each gravel texture basically consists of two parts, the base texture and the variation texture. The base texture contributes the displacement and normal maps, which are unique to the gravel type. The variation texture contains diffuse, bump and reflectivity maps, which are unique to each variation. The displacement and normal maps are used in conjunction with the variation texture on render time.
AO, edge and mask maps can help you create your own gravel textures e. These variation textures are to be used in conjunction with the gravel base textures, mentioned above. All gravel textures, base and variation, come in three different scales: This allows you to choose the scale that fits the requirements of stoen 3D scene best, i. With their power-of-2 resolution of px x px, these textures are perfect in real-time applications, e.
There is more than one way in which these gravel textures can be used. Depending on the capabilities of your rendering stine, several different techniques might be available, such as Normal Mapping or Displacement Mapping. These textures are on the low-end regarding the demand they put of hard- and software. Any PC that is not older than, say, 10 years should have no trouble with them whatsoever.
Most 3D applications these days support at least basic normal mapping; many do also offer displacement mapping or similar advanced techniques. There are inherent limitations when it comes to gravel textures. No matter how well the texture is made, how precise its normal or displacement map describes the virtual gravel surface, it still is just a two-dimensional approximation of a complex three-dimensional structure. One that is widely used is displacement mapping.
Although certainly an improvement, the illusion breaks down quickly once one gets too close. Since polygon counts matter less and less these days, it has now become a viable approach to render complex surfaces, such as gravel, as real 3D geometry.
The only remaining difficulty, is to produce the actual 3D mesh data. We wrroway developed a special simulation software that is capable of randomly creating different styles of pebbles, as well as scattering hundreds of thousands of them physically correct onto a specified area. The finished UV mapping is optimized for stone textures with a size of 50cm x 50cm. Using the high-resolution stone textures included in this product, all this allows for even extreme close-ups.
Each individual pebble has been assigned a random material ID between 1 and 10 20 in case of gravel-base This allows for the creation of custom mixtures of different stone types and colors. To have the whole gravel surface as one single mesh object would not be practical. Neither would it be possible to have every pebble be its own mesh object. As a compromise, we’ve fused pebbles into individual pebble clusters of 25cm x 25cm each.
This makes it possible to approximate the shape of a graveled area by deleting clusters outside of the area, while still being not too heavy on the viewport. In addition to clusters, most gravel meshes have also been split into two layers; a top-layer and a bottom-layer, each containing roughly half of the pebbles.
This way arroay can choose which layer is visible, e. For gravel that is farther away or seen from a shallow angle, only one of the two layers may need to be switched on, for instance. The 3D gravel meshes that are contained in this product cover an area of nominally 2m x 2m and 4m x 4m. While both version have the same polygon count of roughly 8 million, the 2m version has four arrowayy more mesh detail per pebble as the 4m version.
Use the 2m version where gravel is seen up close and the 4m version in cases where a larger area has to covered. You can also, of course, combine the two.
In cases where an even larger area of gravel is needed, these meshes do tile seamlessly – just as a bitmap texture would. With the use of mesh object instancing, arrway is possible to cover areas of several hundred square meters, without consuming much more memory as one single gravel mesh would.
Although our gravel meshes have a nominal size of 2m x 2m and 4m x 4m, you are not bound to this scale. Due to the somewhat ‘fractal’ nature of gravel and its individual aroway, it is possible to scale the meshes up or down with basically no limit. In this example, the same mesh works as small grains of sand, medium sized pebbles, as well as larger cobbles.
In cases where a greater mesh detail is needed, our gravel meshes can easily be further subdivided to produce the desired resolution. OBJ files are provided as additional download.
The meshes consist of 25cm-clusters, grouped into two layers, inside one container group. There are 94 distinct stone textures contained in this product disks 4 to 6plus color variations, making for a total of different styles. These stone texture are meant to be used in conjunction with the 3D gravel meshes to produce a large variety of highly realistic gravel styles.
Of course you can also use them for other purposes. Each stone texture has been created so that its inherent variation in surface texture and color mirrors the variability of the whole gravel surface. Because random UV coordinates have been assigned to each individual pebble, different parts of the stone texture will be randomly applied to the pebbles of the gravel mesh when rendering.
Gravel – Volume One | Arroway Textures
You are of course not limited to the set of stone textures included in this product. You can very easily modify these textures to achieve a special look you want, or arrwoay create your own stone textures.
Because the UV coordinates of the gravel mesh respect texture edges, these stone textures do not have to be tilable. Each stone texture has a real-world scale of 50cm x 50cm at a resolution stoone px x px and consists of. Since these stone textures are meant to be used with the 3D gravel meshes, the same requirements apply:.

Comparison of different render techniques Render-Time Usage There is more than one way in which these gravel textures can be used. Below a comparison between these two techniques, as well as our 3D gravel meshes. Several different techniques can be employed stne trying to compensate for this fact. Real 3D gravel is the solution Our Solution Since polygon counts matter less and less these days, it has now become a viable approach to render complex surfaces, such as gravel, as real 3D geometry.
Clustered meshes allow for flexibility Mesh Clusters To have the whole gravel surface as one single mesh object would not be practical. Only use the layers you need Mesh Layers In addition to clusters, most gravel meshes have also been split into two layers; a top-layer and a bottom-layer, each containing roughly half of the pebbles.

Different scales, same mesh Scalability Although our gravel meshes have a nominal size of 2m x 2m and 4m x 4m, you are not bound to this scale.
