Bump and displacement mapping
Both of those effects are only available to TVPaint Professional users.
Bump
The Bump effect allows the creation of a relief, which will be provided by a source image, over the current layer.
The more luminous the source image is, the more important the relief of the pixels in the current image is. The darker the source image is, the less visible the relief is.
On the right below, the source image and the current image are the same. It gives a feeling of relief on the whole screen.

- You can adjust the depth of the relief and soften the borders using the numeric fields Depth and Smooth.
- A relief requires a lighting to be visible : thanks to the Apply with menu, you can define a centered lighting thanks to the Center option, or a directional lighting (Direction option) whose angle will have to be adjusted.
Displacement mapping
The Displacement Mapping effect works the same way as Bump effect: the panel and settings are the same.
Regarding the Displacement Mapping: the pixels from the current image which correspond to the pixels from the source image will be replaced by different pixels from the current image.
That means: the software makes a translation of the current image pixels along a direction or a center, only in the opaque areas of the Source image.

The more luminous the Source image is, the more important the displacement of the pixels in the current image is. The darker the Source image is, the less visible the Displacement Mapping is.
