Hello guys! 
I’m here to demonstrate my new version of adding object in the vertex color.
there are 7 object slots that are added by the color of the corresponding vertex.
I added more freedom to the component, bug fixes and optimization.
Randomize VertexColor: if true, the terrain will be painted randomly.
==== Adding objects ====
Example:
Red Color Object: put the name of the object that is added with the red color of the vertex.
Red Randomize Chance: if “Randomize VertexColor” true, chance of an object being added to the terrain.
Red Obj Position: (Optional) to adjust the position of the added object.
=== ===
this component is able to read the color of the vertices and add objects selected by you;
Is supported: groups of objects or just one object.
now has an extra option!
this option is interesting if you want to add objects specifically at the tips of mountains.
Mountain Height: activate this option if you want to use mountain height
Height: the height of the mountain where you want the objects to appear.
Mountain Object: name of the object to be added.
Mountain Object %: chance of the object appearing on the mountain(1.000 is 100%).
Mountain Obj Position: (Optional) to adjust the position of the added object.
