If we give to " Strength" a positive value, the particles will be rejected by the curve and will be dispersed We select the spiral and add a force that drags the particles along the curve: in the " Physics" tab we add a " Force Field", with Settings > Shape:Curve parameter indicating a force that must attract along a curve We return to the "Particles" tab and remove each initial velocity from the particles, setting in the sub-panel "Velocity" > Normal: 0 m / sĪnd we eliminate the influence of gravity (so the particles will not fall down) giving zero value to "Gravity" in the "Field Weights" sub-panel
This should cause the particles to enlarge and shrink during the movement, emphasizing the shimmer we will provide later. The texture will have to affect only the dimensions, so in the sub-panel "Influence" we check only the "Size" option to which we give value 0.6 In the "Texture" tab we select the "Type": Distorted Noise and the "Amount" parameter: 10 in the sub-panel "Distorted Noise"Īnd in the "Mapping" sub-panel we select "Coordinates": Strand / Particle In the "Textures" sub-panel at the bottom we create a texture and call it "textureparticles"

We add a further "randomness" by resizing the particles according to the position of the moment, adding a texture that influences the size (see also the tutorial how to resize particles via textures ). We also remove the check mark from " Show Emitter", so as not to display the UV sphere emitter during rendering, and set "Scale Randomness": 0.485 to make random-sized particles be emitted We select the UV Sphere, created before, and we associate it with a new "Emitter" type particles system to do this in the Properties Window on the right, in the "Particles" tab, we create the system by pressing the "+" key and assign the value 5000 to " Number", " Lifetime": 2000 and " End": 2000Īnd in the "Render" sub-panel we select "Render As": Object and Object> Instance Object: "Icosphere", thus causing the icospheres to be emitted. Press on the "Filter" button in the Outliner and activate the display filters in the various modesĪnd we click on the option to hide the icosphere in the 3D View, which will remain available to be used in the particles system. Holding the selected icosphere, we press the M key and insert it into a new "Particles" collection. We associate to the icosphere a "Emission" material with a hexadecimal color E7CE5F and Settings > PassIndex: 3 to identify it later in the Compositor
We create an icosphere, scale it by 0.0866 and press CTRL+A to apply the dimensioning. We confirm the resizing by pressing CTRL+A and then selecting "Scale". Output Curve Type: Bezier / Auto, the spiral created must be a Curve and we want it to be smoothed, so we choose the most suitable vertex typeĪs a particle emitter we use a UV Sphere, created by pressing SHIFT+A and choosing Mesh > UVSphere, which we will scale (in this case) to 0.1311 and position it at the beginning of the spiral, more or less at position x: 0.993 and y: -0.14. Height: 1.02, if we do not give a height to the spiral this will remain flat, so we set the height at which the spiral must rise at each turn Steps: 29, each turn of the spiral must consist of 29 segments
Turn: 5, that is we want the spiral to make 5 turns (we will have a "five-story" spiral) Insert the spiral curve by pressing the SHIFT+A keys and choosing Curve > Curve Spirals > Archemedian (ie similar to the Archimedean spiral).īefore performing other operations, in the popup menu at the bottom left To speed up the work we use the Extra Objects addon: Now let's create the spiral that must be covered by particles. We will therefore try to make this animation, first creating the spiral along which the particles will have to move, then the particles emitter, then the force that will drag them along the spiral and, after animating everything, in the Compositor we will add an "sparkly" effect to the particles, as if it were a magic spell. In this tutorial in english for Blender 2.8 we will see how to make an animation of particles along a path, in particular a spiral, to create a particular effect as during the launch of a magic spell.
