Default Scale
Define the default scale of your instances
Default Scale
The "Default Scale" of your instances. If not toggled, the default scale will be of the value (1,1,1).
Reminder
Don't forget that in Blender, it's important to apply the scale of an object, when you consider that this object is in its default scale.
Space Option
The "Space" method will enable you to define if your instances should scale with their local surface scale, or stick to the (global) world-space. If the default scale feature is disabled scatter will automatically pick the same space of your distribution method.
Random Scale
Randomly scale your instances
Random Scaling Factor
The "Random Factor" feature randomly multiplies the current scale of your instances by a factor varying between '1,1,1' and your specified vector value.
Example
An input value of '2,2,2' will randomly grow each instance between 1x and 2x their current scales on all XYZ axes. An input value of '1,1,0.1' will randomly shrink your instances on their Z axis between 1x and 0.1x their existing Z scale.
Uniform/Vectorial Method
You can choose between a Uniform scaling, where all X/Y/Z dimensions are scale together or Vectorial scaling where each individual X/Y/Z values are randomly multiplied in an independent manner.
Randomness Probability
The probability percentage slider controls the bias of the random allocation of the scaling factor.
Example
A percentage of 50% means that the randomness distribution is evenly spread between 1,1,1 and the given vector. When nearing zero, we'll have much more chance to have numbers close to 1,1,1. When nearing 100%, we'll have much more chance to have a number close to the input vector.
Shrink & Grow
Change your instances scale based on a mask
Shrink & Grow
The "Shrink" & "Grow" features will multiply your scale by the given vectorial factors.
These two settings are meant to be used with a feature mask, to easily and precisely control your instances scaling with the help of weight painting for example.
Scale Fading
Fake environmental perspectives by scaling far away instances
Scale Fading
The "Scale Fading" goal is to intensify your scenery perspective by emphasizing your instances scales.
Rely on Camera
Note that this feature will rely on the active camera & its dependencies. This effect is not suited for all use cases, especially for animations, as the viewer might notice an active change in scale.
Random Mirror
Add variations easily by scaling your axis by -1 value
Scale Mirror
In order to hide the repetition of your instances, the "Random Mirror" feature will come in handy! It will randomly multiply your scale vector by -1 on the chosen X/Y/Z axis.
Tip
Try to avoid using this feature with instances containing writings of any sort of logo where the reading direction has an importance.
Overall Minimal Scale
Avoid un-realistic instance's scale
Minimal Scale
It is quite common to stumble on instances that are way smaller than reality in your scatter-system(s). That's where "Overall Minimal Scale" comes in handy, this feature will remove or adjust scales of instances below the given threshold.
