With this Splatter Generator, you'll be able to draw curves and create any splatter you want using geometry nodes settings in the modifier tab.

You can add any color or texture, and you can choose any object to be the target for the curve so that when you draw the curve it draws on the object's surface.

Check the video to see all what this Splatter Generator can do, and think about how much time you'll save by using it rather than making your own splatter.

So there is no need to install it.

You extract the file from the zip and open it directly with blender.
