Hello,
Im trying to make an animation of a machine applying spray paint to a wall. Im very new to blender and im wondering how I would go about making this animation. It’s a simple drawing that moves up and down but im having trouble applying the spray paint. Any tips would be very helpful, thanks.

You will need to use a particle system to represent the paint being sprayed, not an easy task for a beginner I must say, perhaps you should try something a little easier to start with! Then you will need to play around with opacity of the material for the surface being sprayed, i.e. animate the opacity levels as the paint is applied. For this you need to decide whether you are going to use Cycles render or not, personally i would. You can simulate a surface changing colour by having two colour feeds to your material and gradually animate the change from one to the other. The paint itself is going to be a huge headache for you until you are pretty familiar with Blender.
