Change a Map (Substrate)

In some cases, it’s necessary to replace a map of a scanned or finished material. Most often, this involves swapping the diffuse map to introduce a new pattern while preserving the other captured reflection details.

Please note that this is an advanced change. If you are not sure what this option does, we recommend not using it.

The best way to start is by copying an existing material, such as a substrate scan (see Copy a Material). Once you open the copied material, you will see the original set of textures displayed.

Next you would need to add a new Texture Set:

Inside the new Texture Set, upload your new map (in this case, the Diffuse Map) by simply dragging and dropping it, as shown below:

Do not upload the texture into the existing Texture Set, because the system will interpret the newly uploaded texture set as an updated version of the original and overwrite it.

You will also need to specify the size of the new map. Make sure the physical dimensions match the real-world size represented by the newly uploaded texture:

and then press Save.

Once it is saved, copy or remember the Texture Set ID (in this case 61012) and navigate to Edit Material:

Then click + Add a new node and select a new Texture Set from the menu.

As a final step, connect the UV output to the X-Y-Z input, and plug the Base Color into the Base Color input of the Principled BSDF node like so:

Once you are finished, save the material.
