Brush Shaders

Brush Shaders are shaders that allow you to easily to add or remove voxels from the volume by selecting the area in which you want the shaders to take effect.

How to use a Brush Shader

1. Select Voxel Shader Mode [C]
2. Select either:
   • Attach: to add new voxels (existing voxels are not removed)
   • Erase: to erase existing voxels (new voxels are not added)
   • Paint: to change existing voxels (voxels will not be added or removed)
3. Select the shader in the Shader List

Restricting voxels (painting existing voxels)

By default, Brush Shaders are used with the Voxel Shader Mode as shown above.

However, the Paint mode can also be used to replace only selected voxels. For example, to apply the brick pattern to existing volumes.

1. Right-click the chosen color and select Inverse
2. Right-click any of the selected colors and select Voxel Selection by Color
3. Select Voxel Shader Mode [C]
4. Select Paint
5. Select the shader in the Shader List
6. Draw a box over the volume — only the selected voxels will be updated.
