Rocks are everywhere, in most 3d games. But there is a problem, they take a lot of polygons. Typically it is very hard to have a big realistic rock with less than 20,000 poly. I am been looking for solutions to get the same result with only 600-700 polygons.

… and I came up with some very advanced shading algorithms using the normals to simulate the relief. Better than bump mapping or displacement maps, these shaders are doing the job using low resources in only one pass.

Then I have created 12 low poly rocks, and worked the UV mapping so that these rocks can work with rectangular regular textures. I mixed atlas and spherical UV mapping to get rocks that would almost look good with any kind of seemless texture.

new: added terrain meshes, charcoal, pebble, multi rock groups.

Finally I created 20 hi-resolution textures (2048×2048). They are not photos, but algorithmic simulations so that you get a level of detail that cannot be matched with a photo.

Features in this pack

• 3x shaders: details, wet and transparent. All shaders supports 2 textures (one main and one detail) and 2 normal maps.
• +30 unique and exclusive textures, ice, magma, stone, gems, rocks, stones etc…
• 12 low poly rocks (from 600 to 1400 poly)
• 3 charcoal textures and models
• 3 pebble textures and models
• 10 multi rock groups with low poly and low resource consumption.
• 1 terrain + textures
• 1 scene with HDR enhancement, 1 normal and one for mobile.
• 22 preset materials using the textures and the shaders so that you can drag and drop them immediately.

This pack works with Unity 3 (it uses surface shaders and do is not supported by Unity 2.x). iPhone has not been tested yet, but should work with minimum changes. Free and Pro version are supported.
