![]() ![]() You can duplicate this effect as you like, and offset the keyframing as you see below to create multiple bursts. Select the top vertices of the base object (before applying the modifiers) and then give that vertex group called “top”.Īnimate the scale of the object from small to large, and then modify the strength of the hook modifier (applied to the “top” vertex group), causing the outer edge of the burst to stick to the hook with decreasing proximity. Just make an array of objects and then apply a curve modifier attaching it to a circle curve. Making the ring is something you can find in this tutorial, though it’s pretty easy if you’re experienced with blender. The idea here is to add a vertex group to the outer edge of a ring formed by an array of small objects, then to stick the applicable vertices to an empty hook attractor. Starbursts - Lots of small particles expanding to fill the screen and then fading from view.You can imagine also adding an alpha gradient to the particle to make it appear as if the end is more transparent, like a proper motion blur, but I’ll leave that as homework for now. Excessive stretching may result in geometric abberation, but all in all this is a rather good simulation of a motion trail without requiring real motion blur. Additionally, you can abuse the geometry node to create some interesting colours, by attaching the position output to a colourramp and plugging that into the colour input of an emission shader.įinally, to increases the smoothness, subdivide both the circle and the curve. This is a very easy effect to generate, and you can even duplicate the object and keyframe that for multiple offset motion trails. Simply keyframe these animations to make the desired effect. Note that setting the particle to the world origin will situate it on the origin of the curve. Here, all we need to do is (ensuring you’re in top view), keyframe the x axis position of your particle (use a circle) with a curve modifier attached to your path curve, and you’ll see that sliding it to the right or left will displace it along the curve, and scaling it on the x axis will grow and shrink it along the curve. This is easy to do with the curve modifier, which allows us to constrain an object’s transforms to a curve. Motion trails - A particle travelling along a path with animated colours and “motion blur”Ī motion trail can be simulated by scaling an object along a curve tangent axis.* To stagger the animation effect, go to the animation pane (NLA editor section) and drag the keyframes for the screw modifiers to offset them slightly. * Boolean intersect the two - then, only the parts of the stencil that overlap with our screw object are shown. * Apply a solidify modifier to the screw object, in order to make sure it intersects with our stencil square ring * Add a base for our screw modifier - this is an edge that servers as the radius, that, when the screw modifier is applied, spins into a full circle * Set up the object to be animated, a square can be made by insetting a plane and then deleting the inset ( Ctrl+I) We can combine these effects to generate a circular reveal of any object we want. ![]() Thinking about it like this, we can first define a shape to reveal, and then reveal a circle segment “slice” with an animated interior angle.įortunately, the Boolean modifier lets us hide and show parts of an object, and the screw modifier lets us animate rotation filling of objects. The high level idea here is that the fundamental “animation” is based on a circular reveal of an element (that usually has some radial symmetry, like a regular polygon). ![]() I’ll summarize their procedures below (For advanced users, otherwise, please view the video) In this tutorial, we’ll be making five effects. The Video Sequence Editor (VSE) built into Blender can then be used to overlay these effects on top of your own videos, so that you can create custom effects to your heart’s content, like this one:Īn example of motion graphics that I’m particularly fond of can be found in the trailer for Cyberpunk 2077 (hype!), which displays an incredible amount of detail and skill in the space of a second or two.Ĭheck out the video at 1:24 for the title and 1:32 for the endscreen. These 2D effects come in a variety of styles, and all be replicated using the free Blender software, which also provides incredible flexibility and an extremely powerful modelling/animation suite to generate effects. Typically, motion graphics software like Adobe After Effects can be expensive (thousands of dollars, subscription based models), and difficult to learn. Motion graphics effects are ubiquitous in modern video editing, and can often make the difference between a mediocre video and a polished, professional result. ![]() Five Easy Motion Graphics Effects in Blender (in 15 Minutes!)
