Although the standard list of job preview materials provides a reasonable selection of woods, stones and metals to choose from, you may have a project that requires a special material type. For example, a customer may require their work to be carved into a special wood that is not in the default list of materials.
The Job Preview material list can very easily be edited to include your own material types and selection names, allowing your work to be previewed and saved in the same materials that you are actually planning to rout or engrave.How do I add new material image files to the available list?
From Aspire 4 / VCarve Pro 7 onwards you can add new images to the Material Images folder in your Vectric Files folder.
In Aspire 3.5 / VCarve Pro 6.5 or earlier you will need start the program and use File > Open Application Data Folder. This will open a new window showing all the program's support folders. You can add new material image files to the Bitmap Textures folder.
You will need to restart the software for your new image files to appear in the material drop-down lists.
