With this node, you can paint mask directly in the Viewport and immediately see the results on the terrain. The Painted mask acts like all other masks, but you can edit it in real time as often as you want.
To add a Painted mask node, right-click in the Graph Editor and select Create Node > Mask Generation > Painted mask.
Double click on the node to open its parameters:
To begin editing the mask, check the Edit mask box:
In the dialog, edit the Width, Height, and Quad size of the mask.
The input mask does not give its size to the
painted mask: if it is not the same size, it is enlarged or reduced
when it is copied.
If the input mask changes, the painted mask is not updated automatically. You must click Copy from mask to copy the new input mask. Any modifications that have been painted are lost.
With the Edit mask button activated, use the brush sliders to change the brush size, intensity, and hardness and draw the mask directly in the Viewport. The mask is updated in real time.
The profile is influenced by the hardness of the brush, but neither by size nor by intensity.
For the first profile, here is what we achieve for a low hardness, a medium hardness and a high hardness:
Here is what we achieve for the second profile:
Here is what we achieve for the third profile:
In the Painted mask node, pressing and holding the left mouse button paints the mask. To pan in the mask, you can press and hold the Shift key and the left mouse button, and move the mouse.
Some useful shortcuts:
- S: toggles between the different modes
- D and F: increases or decreases the size
- G and H: increases or decreases the intensity
- J and K: increases or decreases the hardness.
If Instant Terra detects that a tablet is connected, two Pen pressure checkboxes appear in the window.
When the first box is checked, the size of the brush is modulated by the pressure exerted on the stylus. For example, here is a line obtained when the pressure exerted on the stylus is increased.
When the second box is checked, the intensity of the brush is modulated by the pressure exerted on the stylus. For example, here is a line obtained when the pressure exerted on the stylus is increase.
When the two boxes are checked simultaneously, both the size and the intensity of the brush are modulated by the pressure exerted on the stylus. For example, here a line obtained when the pressure exerted on the stylus is increased.
It is advisable to use a soft brush, i.e. a brush with a gradient, rather than a hard brush when modulating the intensity with the pressure exerted on the stylus; otherwise, there is a risk of abrupt transitions when drawing.

|Change mask size||Changes the mask size and keeps the current mask or clears it.|
|Set to black||Clears the mask and fill it with zeroes.|
|Set to white||Clears the mask and fill it with ones.|
|Edit mask||Check box to modify the brush parameters|
|Brush profile||Displays the current profile of the brush, displayed in the right of the window.|
|Lighter||Draws the mask|
|Darker||Erases the mask|
|Constant value||Sets the value of the mask to a constant value|
|Size||Sets the size of the brush|
|Intensity||Sets the intensity of the brush color|
|Hardness||Sets the attenuation of the intensity of color from the center|
|S||Toggles between the Lighter and Darker brush modes, or between the Up only and Down only options of the Painted mask's Constant parameter|
|Pen pressure||When working with a graphics drawing tablet, you can now use pen pressure to drive the brush size and/or intensity.|
