How to Clean Maxon Cinema 4D Simulation & Viewport Render Cache
Location & Quick Verdict
%AppData%\Maxon\Cinema 4D\cache
Maxon Cinema 4D stores physics simulation caches, Redshift material previews, and viewport shader caches on your C: drive.
How Embedded Chromium (Electron / CEF) Caches Bloated Maxon Cinema 4D Simulation & Viewport Render Cache
Modern web browsers and desktop apps built on Electron, Chromium Embedded Framework (CEF), or WebView2 run a full browser storage engine inside %AppData%\Maxon\Cinema 4D\cache. Every inline video preview, animated sticker, PWA offline bundle, and compiled V8 JavaScript script is written into disk-backed Cache_Data, Code Cache, Service Worker CacheStorage, and IndexedDB LevelDB tables without strict disk quotas.
Over months of daily usage, Maxon Cinema 4D Simulation & Viewport Render Cache accumulates 4.0 GB – 28.0 GB of expired media blobs and stale Service Worker caches that are never evicted automatically. Clearing these cache subdirectories forces a clean storage state without deleting your saved passwords, active session cookies, bookmarks, or local databases.
