Surface of the Woods is a collection of 12 high resolution textures from real photographs of ground from various forests in Scandinavia. These textures cover larger areas of ground, up several meters large. Each texture was stitched together from collections of 25-50 overlapping photos, thus creating large textures that still retain a sense of detail!
11 textures are 4096x4096 resolution, with photographic displacement maps, and hand edited displacements to extrude roots, rocks, cones etc more clearly from the bottom. The last texture is a 2048x2048 plant overlay texture.
The material files are made for Poser, but they are essentially just a photo texture with a displacement texture. This means you can use them in virtually any 3d application that support textures. The quality of the textures stand for themselves, and you can of course combine them yourself with more advanced shaders.
