In pCon.planner, materials give object surfaces the appearance of a particular raw material (e.g. glass, metal or wood). To simulate materials, pCon.planner uses the physical material model. This simulates what a material looks like when light meets its surface.
A physically correct material has different ways of interacting with light: Light is reflected, refracted or absorbed. A material becomes visible to us because it reflects incident light. Furthermore, we are able to see materials that shed light by themselves. To read background information on the physical material model, please follow this link.
pCon.planner displays complete materials in Realistic mode as well as render styles based on Realistic mode. Photo-realistic rendering also processes these materials. Other render styles do not display materials or only display simplified versions of them (e.g. in Shaded mode, color textures are displayed, but not Normal Maps).
The Material Editor is the tool for displaying, creating, modifying and managing materials. It is opened from the Material Editor button in the Material group on the Edit tab or from the toolbar.
The toolbar is located top left in the Material Editor. It contains a number of functions: |
Create Standard Material: The small arrow to the right of the plus symbol will open a selection of material templates (see below). |
|||||||||||
Select material template after clicking on the arrow: Generates a new standard material, glass or self-illuminating material. |
|||||||||||
Delete an existing material: A deleted material can be restored using the Undo command (Quick Access toolbar). |
|||||||||||
If the pipette is clicked onto an object in the design, its material will be selected in the Material Editor. The pipette is also used to sample the color from objects in the design. Sampling means that it will be automatically converted into a material in the Material Editor. |
|||||||||||
The material selected in the Material Editor can be assigned to a surface within the plan by clicking on it. In addition, you will also find the function Replace Material: Click on the paint bucket and then open the context menu (right click). This option will replace the material on the selected surface within the entire selection as well as all surfaces of the object that use the selected material. |
|||||||||||
Assigning a material to a selected object: The objects will be completed coated with the material. |
|||||||||||
Duplicating an existing material. For example, this function is useful for making a copy of write-protected materials so that they can be modified. |
|||||||||||
Deleting all materials not assigned to objects. If unassigned materials should be retained, do not use the local function in the Material Editor. Instead, use the global Purge function in the Application Menu. |
|||||||||||
Calling up the filter menu. Here you can search for materials by name or filter based on specific criteria.
|
Right beneath the toolbar is the Material Browser. It shows materials used in the current design. The image on the left shows three materials.
|
A right click on a material in the Material Browser will open a context menu. |
||
Select the objects in the design which use the material currently selected in the Material Browser. |
||
Extend the selection in the design to include those objects which are using the selected material. |
||
Remove objects with a chosen material from the selection. |
||
Load a material from a file. |
||
Import material parameters and replace the parameters of the active material with them. |

pCon.planner’s physical rendering differentiates between the various material types. The interaction from light and material is controlled through the material properties. The selected material type influences the behavior of the light when interacting with the material.
• | The specular portion of the light is reflected directly at the surface. |
• | Diffuse reflection is caused by the scattering of rays of light within the material: rays of light enter into the material and are deflected into different directions. |
• | Metal materials only have specular reflection, non-metals reflect predominantly diffuse. |
• | Depending on the properties of a material, the light rays enter deeper into the material. They are ei-ther passed through the material (transparency), thrown back within the material (translucency) or swallowed by the material (absorption). |
The following material types, which set the various interaction possibilities for light and materials, can be found in pCon.planner. For each material type, you will find various setting possibilities. When you create a new material in the Material Editor, you will immediately choose the type. To do so, click on the small, black arrow next to the plus symbol: • Standard – Metal or Non-Metal • Glass • Luminous In addition, there are two other types of material: photometric diffuse and photometric advanced. These are relevant for the planning of lighting scenarios.

Parameters for Standard and Glass Material
Color/Texture A color or texture is the base of every material.
Roughness The degree of roughness defines how smooth or rough a surface looks. Depending on the roughness, the specular reflected light will be scattered more or less strongly.
|
Brightness
This parameter defines how light or dark the base color or texture of a material is.
• | 0% Brightness: The material does reflect only little light, it appears almost as black. |
• | 100% Brightness: The material reflects strongly and appears almost as white. |
• | The values on the scale define how intensive a color is or how distinct a texture appears. |
• | A base texture can be brightened or darkened, a predefined color can be altered. |
• | The brightness defines how strong the specular reflection of metal materials is. |
Transparency
• | Transparency determines what portion of rays of light passes through the material. |
• | For a standard material, values of 0% (not transparent) to 100% (completely transparent) are possible. |
• | Materials with a base texture as well as those with a base color can be assigned a transparency value. |
• | Even if a glass material is nearly completely transparent (with a value approaching 100%), a slight specu-lar reflection will stay visible, preserving the gloss of the surface. |
Standard Material: Metallic
• | In the physical world, materials are either metallic or non-metallic. Therefore, the Metallic control should either be set to 0% or to 100%. |
• | Intermediate values are used to simulate polluted metal or metalloids. |
• | The metallic value can also be controlled via a map: Light image areas are marked as metal, dark areas are interpreted as non-metal. |
Glass Material: Refractive Index
Normal Map
|
Use an external image editing program to derive a roughness map or a normal map from a texture.

Create Color Texture Pictured on the right is an image that has still to be reworked to function as a texture. If the texture is put together in tiles, the transitions should be invisible. In our example, we created seamless transitions by mirroring and copying parts of the image in an external image editing program. We recommend using high-definition scans of your materials or looking up premade textures on the internet. Please keep in mind that the texture should be seamless. In this case you can go without image editing. Click the |

Create Roughness Map Save the texture under a new name to create an image containing roughness information. This Roughness Map uses greyscale. In our example, the map was created by inverting the texture and by resetting the saturation.

|||||
Create Normal Map For the Normal Map, the areas of the texture are colored in an external program with RGB values to create a relief. The relief of a normal map itself does not cast shadows, but makes individual pixels appear oriented differently. Click the |
Create Metallic Map
For metal materials, the metal property can be controlled via a map: bright image areas get metal properties, dark ones are interpreted as non-metal.
The Metallic Map is used, for example, on metal surfaces with rusty areas.
Click the icon in the Material Editor (Metallic area). Select a texture from your local file system.
Placing and Rotating Texture and Normal Map
Color Texture and Normal Map have an area of placement. Here you can set the width, height and rotation. Roughness and Metal Map are initially linked with the texture values: changes to the texture will be adopted to the maps. If you would like to adjust the position of the Normal Map independent of the texture, click on the pencil icon in the Normal Map area. Input fields will then be available, in which you can individually position the Normal Map. |
Parameters for Luminous Materials
Luminous materials are based on a color as well as a lumi-nance. A transparency value can be assigned in addition. The shader automatically adds a blooming effect to lumi-nous materials. Blooming creates a soft glow in the direct environment of a luminous object.
|
We recommend selecting one of the templates from the Material Editor: Click on the small arrow next to the plus symbol. In the drop-down menu, hold the mouse over the templates. An additional menu will open with various material templates.
Please note the difference between material type (glass, standard and self-luminous) and template: A template is always based on the type of material: frosted glass is based on glass, wood, fabric or plastic is created using the standard material...
A huge variety of materials which you can use for your designs is provided in pCon.catalog.
Clicking on the Materials catalog in the Catalogs group (Start tab) takes you to the world of materials of EasternGraphics. |
Note: Material templates from the material editor will be loaded in the material editor for further editing. Additionally, materials from the pCon.catalog can be assigned to an object directly after they are selected.
There are several ways of assigning materials to objects.
Assigning a Selected Material
|
Replace Material
|
Assigning a Material to a Previously Selected Object
|
Assigning a Material by Transfer
|
Assigning a Material by Drag&Drop
Materials can be assigned using Drag&Drop, either directly from the Material Editor, from the Media Browser or from the local system. The procedure is the same in each case. Below, there is an explanation of how to assign a material from the Material Browser.
|
To save materials, you can either use the Export item in the context menu (see here) ore drag the material from the Material Browser and drop it into the Media Browser or into any directory of your system. Drag&Drop from Material Browser to Media Browser is illustrated in the next screenshot. It is possible to select several materials at a time (press Ctrl while selecting).
