If needed, download .jpegs for your new materials and save them in your C:\Users\Public\PYTHA\Material folder
In PYTHA, click on the Materials menu
Select Edit material file from the Manage section
Browse to an existing material file, e.g. navigate to C:\Users\Public\PYTHA\Material or for edge banding, C:\Users\ "user name" \AppData\Roaming\PYTHA26.0\pytha_banding_material_eng. Material Files will have the .pymat file extension.
Here you can change an existing material > right click > Edit, or create a new material, right click on the dialog box > new.
In the Edit Material dialogue box, enter the name of your new material.
Click the box marked "Image" in the Texture section.
In the Select Image Files dialogue box, select the downloaded .jpeg image for your new material.
Click the "Attributes" button to add any material specific attributes, such as Edge Material and Grain Direction
Click OK to exit the Edit Material dialogue.
If more than one new material is needed, right click in the .pymat dialogue, select new and repeat the creation steps above
If you would like to add multiple new materials to your .pymat at the same time, right click in the .pymat dialogue, select "New from Textures...". Select all the .jpegs that you would like to create materials for and click Open. PYTHA will automatically add new materials to your .pymat file. These Materials will be named the same as the .jpegs used to generate them and will have the .jpeg assigned in the Texture field. You can then right click any Material and select "Edit" to add individual Attributes as mentioned above.
Note: If the .jpeg images used in your materials file are moved or deleted your materials will no longer display correctly in your PYTHA model.
