Description
Forces the path tracer to restart sample accumulation, useful when a scene change isn't automatically detected.
Caveats & Gotchas
- • Only meaningful while path tracing is enabled via EnablePathTracing; calling it otherwise has no effect.
- • The path tracer normally auto-detects scene changes and restarts accumulation on its own — this exists as a manual override for cases where automatic detection misses a change (e.g. certain material parameter or non-visual state changes).
- • Restarting accumulation means the image goes back to a noisy, low-sample-count state and needs time to converge again.
