The Dust Fraction property of a Galaxy Nebula object represents the fraction of the object's mass that is present in dust, relative to the amount of mass in gas or stars. The Dust Fraction affects the object's appearance, as dust will appear as an opaque cloud in the nebula. The Dust Fraction, Gas Fraction, and Star Fraction values will always sum to 100%.
The Dust Fraction is automatically calculated by Universe Sandbox based on the Galaxy Type and the nebula's position within the Galaxy. However, the user can change the Dust Fraction, which will automatically turn off the Enable Nebula Evolution toggle for the individual nebula.

Dust Fraction is a unitless property between 0 and 1, but it can be viewed and edited as either a fraction or a percentage.
