This is a Grey and Blue Metallic Gravel Texture, it has been made with Materialize, the textures are in 4096x4096 png files, it is seamless and PBR.
The preview images are screenshot of the material in Materialize.
In the uploaded files, you will find a 3D file where the textures are applied to a plan scaled at 2 with a PBR node, the available formats for it are : .blend, .abc, .dae, .fbx, .glb, .obj, .mtl, .ply, .usdc, .stl and .x3d. The native is blender so it is in cycles, you ca find the complete node tree in the shader editor. In Blender you just have to shift in the Render Mode to see the displacement of the texture.
Then you will find a .zip file wher are compressed the folowing textures : diffuse, ao, normal, height, metallic, roughness, smoothness and edge. All the texture are not especially necessary to build the texture but I uploaded it anyway in case you would need it. You will find in the .zip file a .mtz load file, if you get Materialize, you can load a project and select this .mtz file to open all the textures in the software.
I am at your disposal if you have any question.
Thanks, enjoy !
