Now let's really jump into the deep end of the pool and look at a much more complex example. Note that Lens Blur has a 'Blur Focal Distance' that selects where in the gradient the focus is.FlickerDur = random(flickerDurMin,flickerDurMax) A quick blur map was created using a shape layer with a Fill Gradient. Here is the AE project file: Tao_Maelstrom_CC12.aepĭepth of Field was added using AE's built-in Camera Lens Blur effect. And a texture was used to create the lines on the surface. Also the different Fractal>Individual Freq were changed. To make the 'Tao Maelstrom' effect the Fractal settings were changed to use the positive side (positive Amplitude) of the MultiSmoothRidge fractal. Here is the final video:Īnd here is the AE project file for it: Tao_Plastic_Vortex_CC12.aep IBL was setup with the 'Dark Industrual' environment (very high Diffuse, like 1000 to get some diffuse from it). To make the Plastic Vortex, the Material color was changed to Orange.

Here's a quick explanation of setting it up: I recently posted some Tao vortex videos on my Instagram ( trapcode_lab) and got many questions on how it was made. Sum += thisComp.layer('MIR').effect('Mir')('Scroll X').velocityAtTime(time +i*0.1) This is so that the camera aims in the direction of flight. Lastly there is an expression on for the sideways direction of the camera (yaw). One second is added to the sampling time so that the banking happens first, before the actual turn. Lots of smoothing is needed! By sampling the velocity of the Scroll X motion we get an approximation of the banking needed for such a turn. Here we are again smoothing the alredy smoothed values of Scroll X. 0.1*sum/10 // change the value (0.1) to change the amount of banking Sum += thisComp.layer('MIR').effect('Mir')('Scroll X').velocityAtTime(time +1 +i*0.1) smooth the velicity values to avoid jumps To get the banking effect (roll of camera) an expression is used on the Camera Z Rotation: The wiggle expression creates the randomness and uses the aforementioned random seed to do so. The rest of the expression is a smoothing window to smooth out the result of a wiggle expression. Simply changing the seedRandom value here will change the entire flight path.
