In Pete’s lesson this week we were working on simulating volumetric lighting in After Effects, in the end we wanted something similar to the GIF on the left (Pete’s example) which I got somewhat close to actually, I could only include a screenshot as rendering the full animation out would have taken a large amount of time which I didn’t have by the end of the lesson, the only things I was lacking from Pete’s example was animating the lights behind the logo to shine through more and twinkle overtime, more intense light and having the logo zoom out, I have set a goal to make another with my own logo and improve on the things we learnt in the lesson.
Here is how I did it, sorry for the lack of detail.
- New composition, 720p, 25fps and 10 seconds long.
- Insert the vector Magnetic North logo into the timeline.
- Position it centrally, turn the 3D layer on and push back on the Z axis.
- Use a grey solid to make a ground for the logo.
- Turn on accepts lights/shadows and cast shadows on the Magnetic North logo.
- Make a new point light that has cast shadows enabled and have it behind the logo to cast shadows towards the camera.
- A second light needs to be created to illuminate the front of the logo, this time a spot light that didn’t cast shadows.
- Make a 1-node camera with a 28mm lens and DOF enabled.
- Create a new white solid and place it behind the logo, used to mimic a light source. Use the ellipse mask tool to shape a new solid to size, I did mine to look like a torch light. Turn on 3D, push it back in the Z axis and in material properties turn off accepts lights.
- Create a Null , make it 3D and name it volume control.
- Create an adjustment layer at the top of the stack and have a radial fast blur applied, set to a strength of 70 and its blend mode set to brightest it can be.
- parent the centre of the radial blur to the Null layer.
- Add Curves twice and do some colour correcting to mimic the logo, above and below CC Radial Fast Blur .
- Create another white solid and add fractal noise effect to it, change the effect type from basic to dynamic, change the rotation to 200 and contrast to around 220.
- Add an ellipse mask over this and feather it out in the mask settings. Soften the edges using an effect called “Solid Composite” and change it’s colour to black.
- In the fractal noise settings, change the blending mode to none and add an expression to the evolution “time*175” which will animate the cloud looking solid to look more like smoke and offset it behind the logo.
That’s about all I did before the lesson time was over, I really enjoyed this lesson as it has gave me quite a few ideas for what to do with me own logo and hope to work on that soon.
