Eraser | Substance 3D Painter

Eraser

The Eraser is a paint tool that erase/hide what has been painted previously by other tools. This tool only affect one layer at a time.

The Eraser share common parameters and behaviors with the Paint tool. To know more about the brush, alpha and stencil controls take a look at the Paint tool page.

Note:

Technically, the eraser doesn't really remove information. It simply set the layer alpha back to zero which erase/hide the previous painting information. This means :

  • Any previous brush strokes that was painted are still computed when a project is reopened before the brush strokes with the eraser are applied.
