• Heightmap based blending - Textures can be blended with heightmaps/bumpmaps with custom intensity. - Implemented by @ZaPx64
• Paint locked areas - Areas on the terrain can be locked so you don't modify completed parts

How To Use

Watch the tutorial video! https://youtu.be/n5WeAqeea1c

Add the node - To add a terrain node, in the "Add node" screen, search for "Node3D->TerraBrush" ()

Update the terrain

Some properties of the node require the terrain to refresh (mainly for the shaders and stuff). If something does not refresh, hit that "UpdateTerrain" button! For example, if you add a new texture, add foliage, add an object, add a water definition or add snow, you'll have to hit the "UpdateTerrain" button.
