Adobe After Effects - Motorcycle Explosion Tutorial

Adding Smoke


Again I am going to use a smoke charge element from  Action Essentials 2 by videocopilot  but again you can find free option detonationfilms or footagecrate . Drag the smoke element into your composition and time it to start at the same time as the explosion.

If your smoke charge appears to be a bit too slow, you can speed it up by applying a time stretch effect. For this, right click the layer and select Time->Time Stretch. Since this is a pretty instant explosion, I like to speed up my smoke to around 30% of the original duration. Now, with the smoke that I am using, the smoke is all white and I want an angry black cloud.

We can fix this quite easily by applying a brightness & contrast effect to the layer and reducing both brightness and contrast to -100.

For further adjustments, you can also add a curves adjustment to the smoke charge and bump up the alpha channel to make the smoke a little more opaque and not so... dainty. We want angry smoke!

Here is the final angry black smoke cloud after all the colour and brightness adjustments applied:
If there are any artefacts around the corners of your black smoke you can remove them by applying a simple mask and feathering out the edges.
We now need to position this smoke element in our explosion. For this, turn the layer into a 3D layer and copy the position and orientation of one of the already placed explosion layers over to our smoke layer.

Scale the layer up and position it so it sits nicely just between the two explosion elements. You may have to tweak it a little bit so it sits into the scene just the way you want it to.

Here is the final motorcycle explosion with chunks, explosion, lighting, shrapnel, shrapnel shadows and smoke added. Lookin' pretty cool!

Remember, you can add as many elements into the scene as you need to make the explosion look exactly like you want. We covered all the techniques you need in this tutorial so far.

Finally, let's add some camera shake to finish off this effect!
