Spiral Graphics Inc. has released a royalty-free collection of 127 seamless floor and wall textures, as well as Genetica Viewer, a free texture rendering application.
As well as standard JPEG previews, the texture collection is available in the Genetica procedural texture format, which includes embedded effect maps for use with bump and specular channels, among others.
In addition, Genetica Viewer has been released to allow artists to freely make use of these and other textures that are saved in Genetica's texture format. Genetica Viewer is capable of rendering the textures, along with their corresponding effect maps, at any resolution up to 3,000 x 3,000.
Genetica Viewer can make a number of adjustments to each material, such as re-randomizing the texture, zooming the texture while maintaining seamless edges, and color adjustments.
