Random Seed Settings control the random seed used by supported MegaWorld generation tools. This is important when you want a result to be either reproducible or intentionally different every time.

​
Settings

  • Generate Random Seed tells MegaWorld to create a new random seed before the pass.
  • Random Seed stores the explicit seed value used when automatic generation is disabled.

​
Behavior

  • If Generate Random Seed is enabled, MegaWorld generates and stores a new seed.
  • If it is disabled, MegaWorld initializes the pass from the stored Random Seed value.

​
When to use it

Use a fixed seed when you want:
  • reproducible procedural results;
  • easier debugging;
  • stable iteration while tuning filters and scatter.
Use generated seeds when you want:
  • a fresh variation on each run;
  • quick exploration of different distributions.
