Andrew Alex has shared another free procedural material on Gumroad.
Inside archive, you’ll find .sbsar file which helps you to get any amount of Terracotta Tiles textures for blending. Also, I included 2K textures. ( …_RMA is separated texture which includes R-Roughness, G-Metallic, and B-AmbientOcclusion).
You can use it in your commercial and personal projects for free.
Full Substance .sbs project available here for $7. Find the artist on ArtStation for more cool stuff.
