Codename: Fire Ring | Update 28

[h3]Update 28[/h3]
Fire Ring introduces a collision model that simulates an impact shockwave across the surface of an object, as part of our work to continuously improve collisions. In addition, there are improvements to object trails, additional object information, bug fixes, and more.

[h4]Shocking Collisions[/h4]
Object heating from impacts now realistically moves over the impacted object as a shockwave. Fragments are ejected from the edge of the shockwave at more realistic angles. Learn more in our Collisions guides:
Guides > Tutorials > Planetary Collisions Guides > Science > Collisions: Energy, Mass, and Speed



[h4]Impactor Heating[/h4]
Both objects involved in a collision now experience collisional heating on their surfaces, instead of just the larger object.



[h4]More Highlights[/h4]

• Grazing collisions now look more realistic with shockwaves and surface dragging
  

• Object trails are now projected back in time to show their full past trajectory
  

• Objects now have additional information (like, planet, moon, rogue object) in the property panel based on their relative motion around other objects
  

• As we work toward making our simulations more deterministic, seeds for randomized simulations are now easier to find, allowing you to recall previous random scenarios
  

This update includes 6+ additions and 22+ fixes and improvements.
