Making Sparks
1. First create the geometry of the emitter;
in my case it is a cone that represents
a firework.
2. Create a spray particle emitter and
orient it to shoot upwards out of the top of the cone.
Spray particle emitters can be found on the geometry
particle systems roll out.
Right click on the spray ,select properties ,and
then change the object channel to 1.
Set
viewpoint count = 1000
render count = 300
drop size =2
speed =300
variation = 32
At this point your scene should look something
like this:
3. The next step is to apply gravity to
the sparks
To do this select the space warps tab and go
to the particles and dynamics roll out tab.
Select gravity and apply it in the top viewpoint.
Set
gravity = 15
decay = 0
Select Planer
4. Now bind the gravity to the particle spray using the bind button.
5. Now create the ground that the firework will sit on with a quadpatch.
6. On the same plane as the quadpatch create a
deflector.
Deflector can be found in the particles and dynamics
rollout.
This deflector will keep the particles from going
through the quadpatch.
Set
bounce = 1.5
Next Bind the deflector and the spray to each
other.
Your scene should now look something like this:
Now all we have left to do is add glow to the particles. This is processor intensive and will slow rendering times.
Go into video post and select the view that you want to render
Then select glow (frame only) for you image filter event.
In the glow setup select object channel 1, and a size of 17.
You are now on your way to create sparks in any scene.
OK maybe it needs a little more variation and less glow.
