VRMat migration utility tool


This command line tool allows batch migration of outdated XML-based .vismat or .vrmat files.

By default each file is updated to a version corresponding with V-Ray 5.1. This output version can be specified to accommodate for earlier V-Ray versions as well.
Note that legacy .vismat files that are not xml-based will not be migrated. If the contents of a .vismat file are not readable when opened with a text editor, it means the file cannot be migrated.

Usage:

vrmatmigrate [-h] [-v version] [-ow] [-gh] <paths>...

Command line options:

-h : Displays the tool's help info and a version lookup table
-v version : Upgrade the file(s) up to the specified version instead of the latest
-gh : Generates the color/float texture handler plugins
-ow : Overwrites the input file on save, instead of creating a copy with appended "_mig" suffix
-s : Specifies to search the subdirectories if the input path(s) are directories
<paths>... : One or more paths to files or directories to search for vismat/vrmat/vropt files

Example:

vrmatmigrate -ow -s "C:\%UserProfile%\Desktop\legacy_vismat_mtls"

blendimg


This little program can be used to blend multiple images together. Originally it was designed to blend images produced by the photon mapping engine of V-Ray when you need to shoot an enourmous amount of photons. It can also be used to sort of render progressive path tracing in distributed rendering mode, where you blend the PPT images produced from several different machines.

vrscene dehexer


This tool can be used to un-hex vrscene files written with hex-encoded transform and/or mesh data. The resulting un-hexed vrscene is written out separately. Another use for the tool is to compare vrscenes and return a status (false) if they are different.

Usage: Run the executable from a command prompt.

  • to un-hex a vrscene, use the -u flag. Example: vrscene_dehexer.exe -u source.vrscene result.vrscene.
  • to compare vrscenes, use the -d flag. Example: vrscene_dehexer.exe -d scene1.vrscene scene2.vrscene.
  • run the program without arguments to print a help message.
