Decorations
Decorations (decals) are those small patches of grass, mushrooms and flowers on the ground. They are different from textures in that they're 3D models. In this mode, you can manage decoration groups and add/remove decorations on the map.
You use brush to paint on terrain - whether it's height paint, texture paint, or anything else.
Radius of the brush. The larger the size, the bigger the area affected by brush.
Currently, brush supports 3 shapes: Square, Circle, Diamond. Circle is the default shape, and is usually enough for most cases.
This panel contains all 255 available decoration groups, as well as a special empty group. Each group is marked with a color - grey if the group is ineffective, green otherwise. The empty group is marked red. A decoration group is ineffective if it contains no decoration types, or if all decoration types contained in the group have weight 0. This means that painting on a terrain with ineffective group yields no visual changes to the map.
Select a group from this panel to edit it in decoration inspector. When you select a group, all positions on the map that are painted with that group are marked violet.
You can't modify individual decorations on the map - the inspector instead allows you to modify the selected decoration group.
Each decoration group consists of 30 entries, 29 of which are editable in the editor, and the remaining one being always empty. Each entry contains 2 positions: Object ID and Weight. If the group contains multiple entries, the editor (and the game) will randomly assign one of the objects for each position the group occupies on the map.
Use LMB to paint areas with decoration brush. If you want to clear decorations, select the special empty group. Use RMB to select the group that's used on the map at the 3D cursor position.
