Settings → Plugins → Blender preview (namespace preview-blender):

Key	Default	Meaning
`enabled`	`true`	Register the renderer and the conversion route.
`routePath`	`/api/preview/blender`	Authenticated conversion route. Must stay under `/api`; otherwise the authenticated fence is bypassed, so it falls back to the default.
`extensions`	`["blend"]`	Suffixes that open in the 3D preview.
`blenderPath`	`""` (auto)	Absolute path of `blender.exe` / `blender`.
`cacheDir`	`""` → `~/.dsh/cache/preview-blender`	Where exported GLB files and scene JSON live.
`timeoutMs`	`180000`	Wall-clock ceiling for one cold conversion.
`maxBytes`	`1073741824`	Largest `.blend` converted (1 GiB).
`applyModifiers`	`true`	Apply modifiers during export, so the preview matches what Blender renders.
`cacheEntries`	`24`	Cached conversions kept on disk before the oldest are pruned.
