DIRT AND GRIME (WIP)

An important part of the immersion when flying an aircraft in the simulation is seeing how the activities you participate in affect the aircraft you are flying. This isn't just limited to simulating internal wear and tear however, as it can extend to the airframe and visual assets as well, and it's encouraged to set up your aircraft correctly to reflect this.

In Microsoft Flight Simulator 2024 there five different types of "dirt" that can be applied to an aircraft:

• Simple dirt
• Insects
• Runway
• Dust
• Leaks
• Mud

The dirt getting more and more dense is achieved in two different ways depending on the kind of dirt :

Progressive Blend: simple opacity variation from 0% (or a low limit) to 100%.
Progressive Mask: the texture with grey levels (top) is contrasted with different thresholds (bottom) (the *Frost* shader is based on this technic)
