Option consistency

Options were grouped more consistently between paint modes in this release. Stroke modes can be changed via a drop-down menu and by pressing A in the viewport. For modes that support masking, A selects everything instead, when masking is active.

Spacing Pressure Support

Spacing based on stylus pressure. More pressure means dabs are closer together.

Absolute Jittering Mode

Jittering of strokes in 2.66 is done relatively to the brush size. It is possible now to set the jittering amount in pixels, keeping the size independent and allowing for brush spreads greater than before. To switch to absolute mode, press the lock icon next to the jittering amount slider.

Overlay support

All paint modes that use textures now support overlay. Overlay now works slightly differently than older blender versions. There is separate overlay control for the brush itself (under the tool options) and for brush textures. There is also the ability to turn a specific overlay off while a stroke is in progress by clicking the brush icon next to the overlay slider.

New Texture Mapping Modes

Random mapping

Simply picks a random texture coordinate to sample from for each dab.

Stencil mapping
