Quixel

Quixel have just released Quixel Mixer 2019 which is currently free while in beta. Quixel Mixer is a PBR texture generation tool that works by blending and modifying existing textures in layers, which can then be modified using a number of different tools, enabling you to create amazing textures in a very small amount of time. Quixel Mixer is tightly integrated into their own MegaScans texture library, although you can easily import your own PBR materials, such as those found here. We took an in-depth hands-on look at Mixer . The 2019 release brings several new features to the table, including a ton of new procedural masking tools such as pattern generators and new noise modifiers.
