These height maps have been generated using intricate 3D models of fabric created by me.Using only a height map/displacement you can achieve beautiful perfectly tileable fabrics in whatever renderer you choose.I've also supplied a demo scene for C4D and Octane that was used to create the thumbnail for CGTrader.
Feel free to rip the thumbnails to use but they are extremely compressed jpgsThe original 30 files are lossless tileable 4096x4096 PNGs
