  • Press Shift before clicking the button in order to use it exactly as Shader Maker described here: Shader Maker

  • If you have many objects selected in addition to the active object, the material will be added to all the selected objects provided that the selected objects do not have any material on them.

Add New

  • Object Mode
    • This button loads the materials and applies them to the selected object, if no object is selected, this will have no effect.

  • Edit Mode
    • If you are in Edit mode and have a face of the selected object selected, the material will be applied only to that face if there are already 1 or more materials on the object.

Note

This button will always add a new material to the list of materials of the selected object, if you want to replace the active material, use the Replace button described below


Replace

Tip

Only from Extreme PBR Nexus version 4.1.120

  • If you are replacing for example the Asphalt 001 1k Material with Asphalt 001 2k, Extreme PBR recognizes that the material is the same and only replaces the textures inside it, keeping the values of the Material Editor settings unchanged.

  • If you want to replace the same material that is present on multiple objects, you will simply have to select all the objects Extreme PBR checks if the active material on the active object is present on these objects, if it is present it will replace every time it encounters the material. This replaces the Replace All button that was present in previous versions.

  • Press ALT before clicking the button to add a Basic material (Principled BSDF + Node Output)

  • Press Shift before clicking the button in order to use it exactly as Shader Maker described here: Shader Maker

Replace

Important

This button will be present only if the material has a Bump / Displacement map if it is not present, it means that there is no Bump / Displacement map in the material.

Tip

If the same identical material is also present on other objects, the displacement will also be activated on the other objects. If you want to avoid this, you can make the material unique by copying it via the Duplicate Material button described in this paragraph: Duplicate Material


Hide Displace

Smart Shade Smooth

Note

Please Update to Extreme PBR Nexus version 4.1.120 or higher to use this feature with popover panel

Smart Shade Smooth Button

The functions present in this panel, allow you to modify more objects at the same time!

  • Type of Objects valid for Smart Shade Smooth:

    (MESH, CURVE, SURFACE, FONT)

If the selected objects are mixed and some are not of these (Type Camera, Empty, etc …) they will be ignored.

Shade Smooth

  • Until Blender 4.0

    If activated the selected objects will be put in Shade Smooth mode, so they will have a smoother appearance. Up to this version of Blender 4.0 if there are marked Sharp Edges they will be ignored.

  • From Blender 4.1 onwards

    If activated the selected objects will be put in Shade Smooth mode, so they will have a smoother appearance. From this version of Blender 4.1 onwards if there are marked Sharp Edges they will be respected.

Example with Shade Smooth Off:

The object is not smooth, the edges are sharp

Shade Smooth Off Example 01

Example with Shade Smooth On:

The object is smooth, the edges are smooth (If there are no marked Sharp Edges)

Shade Smooth On Example 01

Auto Smooth

Note

From Blender 4.1 onwards, the auto smooth will make use of the “Smooth by Angle” modifier (Geometry Node) and no longer of the native Auto Smooth of Blender since it has been deprecated.

  • Until Blender 4.0

    If activated, the selected objects will have Auto Smooth activated, so the marked Sharp edges will be respected, plus you can adjust the Auto Smooth angle between 0 and 180 degrees, by default it is 30 degrees. This function will automatically activate the native Auto Smooth of Blender on all selected objects (Only up to Blender 4.0)

    If deactivated, the Auto Smooth will be deactivated on the selected objects.

  • From Blender 4.1 onwards

    If activated, the new “Smooth by Angle” modifier (Geometry Node) will be activated on the selected objects with which you can then decide whether to respect the marked Sharp edges or not, plus you can adjust the Auto Smooth angle between 0 and 180 degrees, by default it is 30 degrees. (If a “Smooth by Angle” modifier is already present, it will be ignored)

    If deactivated, all “Smooth by Angle” modifiers present on the selected objects will be removed.

Example with Auto Smooth Off:

All the edges are smooth (If there are no marked Sharp Edges)

Auto Smooth Modifier Off Example 01

Example with Auto Smooth On:

Maximum face angle for smooth edges in this example is 30 degrees, so all the edges with an angle greater than 30 degrees will be sharp, You can adjust the angle from the panel that will appear after activating the Auto Smooth.

Auto Smooth Modifier On Example 01

Auto smooth Angle

This button allows you to adjust the Auto Smooth angle, the angle can be adjusted between 0 and 180 degrees, by default it is 30 degrees. This button will be visible only if the Auto Smooth is activated.

In this example the angle is set to 90 degrees, so all the edges with an angle greater than 90 degrees will be sharp, the others will be smooth

Auto Smooth Angle 90

Ignore Sharpness

Note

This button is only available from Blender 4.1 onwards (Extreme PBR automatically detects the Blender version)

If your object has marked sharp edges and you want to ignore them, you can activate this button, in this way the marked sharp edges will be ignored and the object will be smooth.

Example of mark sharp edges:

As you can see in the follow image, the edges are marked as sharp (Blue edges)

Mark Sharp Example 01

Example with Ignore Sharpness off: The angle is 180 in order to see the effect better:

Mark Sharp Example 02

Example with Ignore Sharpness on: The angle is 180 in order to see the effect better:

Mark Sharp Example 03

Apply Modifier

Note

This button is only available from Blender 4.1 onwards (Extreme PBR automatically detects the Blender version)

Warning

If you apply this modifier with the “Ignore Sharpness” option off, the edges that are not smooth will be set as sharp, If you already have edges marked as sharp, these will be respected, but you may have additional edges marked as sharp after applying the modifier. It is recommended to perform this operation only if strictly necessary (For example to export the object to another software)

This button allows you to apply the “Smooth by Angle” modifier (Geometry Node) to the selected objects

Apply Smooth By Angle Modifier 01

Tip

You can use this button to apply the modifier to all selected objects, a function will be executed that will recognize if there is a “Smooth by Angle” modifier and will apply it, otherwise the object will be ignored.

Set By Default

By pressing this button, the settings will be set as default, every time you apply a material with Extreme PBR to your object, these settings will be applied. (This features not work for the Asset Browser drag and drop)

As you can see, if the “Set By Default” button is activated, below it you will see the settings that will be used when applying a material with Extreme PBR to your object.

Set By Default Smart Smooth

Remove Default

By pressing this button, the settings will be removed as default, no default settings will be applied when applying a material with Extreme PBR to your objects.

Remove Default Smart Smooth

Copy Material (Smart)

Copy Material (Smart) Button 01

This button allows you to copy all the materials and the displacement from the active object, directly to the selected objects.

Here is an example, to better understand:

  • In order to obtain this situation, make sure to hold down the SHIFT button and select the objects you want to copy, the last object you select will be the active object, so make sure it is the one that contains the materials you want to copy.

Smart Copy Step 01

  • Once you have selected the objects, press the Copy Material button, this will copy all the materials and the displacement from the active object, directly to the selected objects.

Smart Copy Step 02

Smart Vertex Groups

Note

This button is useful only if you have 2 or more materials on the same object and you are using the corresponding displacement of each material. the displacements must be of type Modifier because if the Displacement is of type Microdisplacement this will be useless. | For more information on how to use displacement, see this section: Displacement


Smart Vertex Groups Button 01

Here is how an object with 2 materials and 2 displacements, one for each material, is presented, thanks to this button the faces with the corresponding materials will be assigned to the respective vertex groups, in this way you can use the correct displacement for each material.

Note how both materials in the list have the displacement active:

Double Displacement Same Object 01

Here’s how I prepared the object for this example, I divided the faces into more so that the division between the two materials is a little less sharp, so I added some edges to “Accompany” the displacement between the two materials.

Object Subdivision For Double Displacement

Bake Editor Button

Bake Editor Button 01

This button allows you to access the Bake Editor Panel, which allows you to bake the materials present on the object

The Bake Editor section is explained in this section: Bake Editor Panel

Remove unused slots

Remove the materials from the object if they are not applied to any face

Purge Data

Purge the project data (Orphan Data) from Materials no longer used, images no longer used, etc …

This button is the equivalent of the “Purge” button present in Blender in Orphan data:

Purge Orphan Data Standard

Show Material Preview

If active, it shows the material previews in the material slots, it is disabled by default to save resources, since the material previews are updated as soon as they are modified, so if you are working from the Material Editor on the properties of the material these will be updated often, slightly slowing down the interface, leave it disabled to save resources.

Show Preview Material Example 01

Docs Helper

The Docs Helper button allows you to access the Extreme PBR documentation, in this way you can find the reference via the button. A popup will open with the link to the documentation.

Note
