maretf create input.png --version 7.4 --format UNCHANGED --filter KAISER- Creates a new VTF from
input.png... - ...with version 7.4 (supported by most Source engine games)...
- ...with the same format as the input file...
- ...and mipmaps will be computed with the Kaiser filtering algorithm.
maretf edit input.360.vtf -o input.vtf --set-platform PC --set-version 7.6 --recompute-mips- Edits an existing VTF at
input.360.vtf... - ...sets the output file to
input.vtf... - ...sets the VTF platform to PC...
- ...changes the version to 7.6 (supported by Strata Source engine games)...
- ...and mipmaps will be recomputed with the default filtering algorithm (Kaiser).
maretf info input.vtf- Prints the VTF's metadata to the console.

Positional arguments:
MODE The mode to run the program in. This
determines what arguments are processed. Valid
options: "create", "edit", "extract", and
"info". "convert" is also permissible and is
an alias of "create" for vtex2 compatibility.
[required]
PATH The path to the input file or directory.
[required]
Optional arguments:
-h, --help shows help message and exits
-o, --output PATH The path to the output file (if the current
mode outputs a file). Ignored if the input
path is a directory.
-y, --yes Automatically say yes to any prompts.
-n, --no Automatically say no to any prompts.
Overrides --yes.
-q, --quiet Don't print anything to stdout or stderr
(assuming program arguments are parsed
successfully).
--no-recurse If the input path is a directory, do not enter
subdirectories when scanning for files.
--no-pretty-formatting Disables printing ANSI color codes and emojis.
"create" mode (detailed usage):
--watch After creation is complete, watch the input
file or directory for any changes and re-TF
the VTF(s). --no is implied on the first
creation pass. --yes is implied after the
first creation pass.
-v, --version Major and minor version, split by a period.
Ignored if platform is specified as anything
other than PC. Note that older branches of the
Source engine will not load VTF versions made
for newer branches. VTF v7.6 is only loadable
by games running on Strata Source.
