VRAD commands - Bradleyp123/Kiwi-Source-OOT- GitHub Wiki

Common options:

-v (or -verbose): Turn on verbose output (also shows more command -bounce # : Set max number of bounces (default: 100). -fast : Quick and dirty lighting. -fastambient : Per-leaf ambient sampling is lower quality to save compute time. -final : High quality processing. equivalent to -extrasky 16. -extrasky n : trace N times as many rays for indirect light and sky ambient. -low : Run as an idle-priority process. -mpi : Use VMPI to distribute computations. -rederror : Show errors in red.

-vproject : Override the VPROJECT environment variable. -game : Same as -vproject.

Other options: -novconfig : Don't bring up graphical UI on vproject errors. -dump : Write debugging .txt files. -dumpnormals : Write normals to debug files. -dumptrace : Write ray-tracing environment to debug files. -threads : Control the number of threads vbsp uses (defaults to the # or processors on your machine). -lights : Load a lights file in addition to lights.rad and the level lights file. -noextra : Disable supersampling. -debugextra : Places debugging data in lightmaps to visualize supersampling. -smooth # : Set the threshold for smoothing groups, in degrees (default 45). -dlightmap : Force direct lighting into different lightmap than radiosity. -stoponexit : Wait for a keypress on exit. -mpi_pw : Use a password to choose a specific set of VMPI workers. -nodetaillight : Don't light detail props. -centersamples : Move sample centers. -luxeldensity # : Rescale all luxels by the specified amount (default: 1.0). The number specified must be less than 1.0 or it will be ignored. -loghash : Log the sample hash table to samplehash.txt. -onlydetail : Only light detail props and per-leaf lighting. -maxdispsamplesize #: Set max displacement sample size (default: 512). -softsun : Treat the sun as an area light source of size degrees. Produces soft shadows. Recommended values are between 0 and 5. Default is 0. -FullMinidumps : Write large minidumps on crash. -chop : Smallest number of luxel widths for a bounce patch, used on edges -maxchop : Coarsest allowed number of luxel widths for a patch, used in face interiors

-LargeDispSampleRadius: This can be used if there are splotches of bounced light on terrain. The compile will take longer, but it will gather light across a wider area. -StaticPropLighting : generate backed static prop vertex lighting -StaticPropPolys : Perform shadow tests of static props at polygon precision -OnlyStaticProps : Only perform direct static prop lighting (vrad debug option) -StaticPropNormals : when lighting static props, just show their normal vector -textureshadows : Allows texture alpha channels to block light - rays intersecting alpha surfaces will sample the texture -noskyboxrecurse : Turn off recursion into 3d skybox (skybox shadows on world) -nossprops : Globally disable self-shadowing on static props
