This tutorial describes how to duplicate and chaotically locate some objects (meshes) on the surface using particles. This method is useful for creation of textures, for example: leaves' texture, macadam's texture, any other objects that are on the surface. We recommend you to take into account not only our advices, but the possibilities of your computer. Afterwards, the created file can serve as a generator of textures (you may replace models by new ones).
1. Create scene with good lighting, orientating on the power of your computer. Also it is advisable to activate Ambient Occlusion, the shadows should be rather soft. In our example only two lamps were used: Area – for shadows and Lamp – for lighting. Locate camera on Z axis so that it is directed downwards and activate «Orthographic» mode. 2. Let's add a cube and make deflector out of it. For this you should delete one upper face and check Normals direction, the normals should be directed inside the object. Then activate options: Field and Deflection ( >> Objects F7 >> Physics >> Panels: Field and Deflection). As a result, we've got a trap for our particles (fig.1). This trap should be transparent. The easiest way to make it is to press button «Wire» in the Material buttons (F5).
4. Add emitter. It can be any mesh-object, in our case it is a plane, approximately 8 times smaller than the size of our deflector (fig.2). It is important to locate emitter and deflector in one single layer, otherwise the particles will go through the deflector during animation.
5. Check the quality of created animation (Alt+Ahift+A) and select any appropriate frame. For example 187 (fig.4). Here, in this frame you may tune the size and location of the arrows (if it is necessary). Check other parameters, colors and then render your created scene.
