By default it has no effect, meaning the layer is fully visible. The geometry mask is automatically available on any layer in the layer stack. Another benefit is that hiding geometry permit to paint on surfaces that weren't accessible before within a Texture Set, this avoids the need to split an object into several Texture Sets for example. It is also non-destructive as it doesn't store geometry information (like faces or vertices) but instead just the mesh name or the UV Tile number, so re-importing a mesh won't break the mask. This new tool is a better way of masking geometry than regular painting (or when using the Polygon fill) because it benefits from several engine optimizations. It is an evolution of the previously named UV Tile Mask that masked geometry based on UDIM numbers.

The Geometry Mask is a new masking tool in the layer stack that allows to hide geometry based on mesh names or UV Tiles. For more details see the technical requirements.

This release raise the minimum version supported of Ubuntu to 18.04 and MacOS to 10.14.
