Flatten Brush

The Flatten brush allows you to easily 'press down' parts of your model into planar surfaces. In addition, you can raise or lower the surface as you flatten it.

Using the Flatten brush, you can add rough flattening to you model, such as enhancing the plane of a model's cheekbones. You can also achieve completely flat surfaces, for mechanical models, walls, etc.

Note: To achieve completely flat surfaces, ensure you are working with a pure white alpha, and that the brush is set to completely cover the area you are flattening.

Flatten flattens the surface towards a plane whose angle is determined by the area immediately under the center of the brush. As a result, using this brush with strokes or alphas that change the angles of areas of the surface may cause the flattening plane to shift around. To flatten to a particular plane, ensure you brush over a relatively smooth surface; for example, use the Smooth brush first, if needed.

Flatten Controls

Flatten: Causes the surface under the brush to be flattened; the area may be pushed in or pulled out at the same time. The flatten slider controls how much the area being brushed over will be moved out from the model (positive values) or into the model (negative values). The default of 0 causes the surface being flattened to stay, on average, at its original level. The standard Z Intensity control controls the magnitude of the flattening effect.
