A set of photo scanned tileable textures I made to get some practice doing this. I shot the images with a Nikon D5500 and then processed them using Agisoft Photoscan and Photoshop.
The pack is made of 4 bark textures, 3 ground textures, and 2 wall textures. Barks are 2048×4096. Grounds and walls are 4096×4096. Included textures are Color, Normal, AO, Height, and a basic Roughness map used for showcasing in Toolbag 2.
