Bomber, Filter Forge's particle-spraying component, is one of the most popular components, and deservedly so: it's extremely fast and extremely versatile. With Filter Forge 5.0, it just got a lot better. Like, infinity times better.
Bomber Plus comes with 10 slave components that let you customize each particle individually, based on multiple random numbers generated uniquely for the particle; its size, rotation and squash; the number of the fractal layer the particle resides on; and its center and bounds. And the fact that each particle is unique means that you can create an unlimited number of particle types.
The subtree of the Particle input of the Bomber Plus component can be composed of multiple components, each of which can have multiple mappable (green) inputs, any of which can be customized per particle via slave components. Essentially, this gives you an unlimited number of particle types, as opposed to just five in the old Bomber.
This simple example shows a Map Switch with a Randomizer slave plugged into its Selector input, which selects any of the 10 single-component subtrees at random:
The next example shows 3 particle subtrees picked for each particle at random, where each of these subtrees is further customized via slave components. As a result, each star in the generated image is unique:
This simple example uses three Randomizer slaves to assemble a random HSY color, which is then assigned to each particle:
In the next example, particles are rotated randomly and get their color based on their rotation: particles whose rotation angle is close to 90 degrees are bright, and the rest of them are dark:
Here's another cool trick with the Rotation slave. The particles themselves are rotated randomly, but the pattern always stays vertical. This is because the particle rotation is compensated by rotating the pattern in the opposite direction by the same amount:
There's a particle customization technique, enabled by Corner X / Y and Center X / Y slave components, which is so powerful that it deserves a special mention. Essentially, it allows you to customize some aspect of a particle based on an external map:
Here's what's going on:
To sum up, a custom map (the radial gradient) defines an aspect of the particle (ray sharpness):
One more example of the lookup technique. This time, we're sampling colors at the particle corners and interpolate them across each particle individually via a custom 4-point gradient. The resulting effect may be very useful for builders of various artistic / painterly effects:
A variation of the same effect, with an additional profile curve for the gradient:
Like Loop or any other slave-supporting component, Bomber Plus is nestable: it can be nested within a subtree of another slave-supporting component, or have another slave-supporting component inside its Particle subtree, or both at the same time.
The key thing to understand about slave components of Bomber Plus is that their output changes depending on the particle currently being rendered. This means that you can use them in the particle-forming subtree to vary any number of parameters per particle.
Here's how to make them work:
First, make sure that the slave components are connected to the subtree of their master's Particle input, otherwise they will have no effect. The Particle input is the only input in Bomber Plus that generates element data for slaves during sampling.
And second, make sure that there are no bitmap-based components between the slave and the Particle input. Bitmap-based components kill the element data sent to slaves by their master, and thus cannot be used in slave-to-master connections.
Filter Forge is – by quite a margin – the most powerful plug-in we've looked at here. That's because it's a tool for creating plug-ins, both generative texture-creation tools and effect filters.
“Filter Forge is an incredibly powerful new Photoshop Plugin. It's simply amazing. It gives you the power to create your own filters (you must run them from inside Filter Forge though) without any programming knowledge at all.”
