WPC decking board 3d model.
In the scene you will find three types of decking with corners and with three different materials.
Ribbing is made using the Normal Bump and Displacement textures.
Wood color can be easily changed through Color Correction, but if you are going to change the wood texture, then note that channel 2 (Map Channel) is assigned to it.
To speed up your work, turn off the Displacement map, it is initially enabled.
