Render Controls - Advanced
CPU usage controls
Render threads- Changes the number of threads Chunky should use while rendering. (Needs restart)
CPU utilization- Adds in sleep cycles to the rendering process to attempt to reduce the CPU usage. Would recommend using
Render threadsfor more predictable scaling.
Some quality/performance related options
Ray depth- Controls the number of times a ray is allowed to bounce without striking a light source before killed. For outdoor scenes a value between 3-5 should typically be enough with indoor scenes benifitting more from higher values around 10. Higher values offer more realistic light bounce however at a cost to render time. Balance this carefully.
Merge render dump- Useful for multi-PC rendering. Merges a renders .dump file into the currently loaded scene combining the total SPP.
Shutdown computer when render completes- Togglable
Fast Fog- Impacts the quality of fog rendering. Typically only noticable if viewing fog through alpha textures which is rare.
Sky cache resolution- Resolution of the rendered simulated sky. Lower values may boost rendering performance at the cost of sky model accuracy. Default 128.
Snapshot output format
TIFF, 32-bit floating point,
PFM, Portable FloatMap (32-bit)
Advanced Octree, BVH, and ESS options
BVH build method-
Emitter grid size- Controls size of emitter grid used for ESS.
Prevent normal emitter when using emitter sampling- Attempts to disable typical random emitter hits which would reduce noise.
Manual renderer selection
PathTracingRenderer- No other renderers are bundled. See plugins.
PreviewRenderer- No other renderers are bundled. See plugins.
