# Anata Retexturing Notes

First need to extract textures from VRM files for convenience

zip pre atlas hairs to be atlassed with character studio (manually done for now until CLI tool is made)

find ./3/ -type f -iname "*1.vrm" -exec dirname {} \; | sort -u | xargs zip -r 3_pre-atlas-hairs.zip

verify zip has all the right files

## Measure how many *1.vrm files there are
find ./3/ -type f -iname "*1.vrm" | wc

## see how many are in zip
unzip -l 3_pre-atlas-hairs.zip | awk '$4 ~ /.*1.vrm$/ {print $4}' | xargs dirname | sort -u | wc

drag and drop into character studio to atlas the textures

see which folder doesn't have "*2.vrm" files

for dir in */; do
    if [ -z "$(find "$dir" -maxdepth 1 -name "*2.vrm" -print -quit)" ]; then
        echo "$dir does not contain *2.vrm files."
    fi
done

use `separate_textures_vrm.sh -c` to separate textures into `textures` subfolder

#!/bin/bash

cleanup=false

# Parse command line options
while getopts ":c" opt; do
  case $opt in
    c)
      cleanup=true
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
  esac
done

# Iterate through numbered folders
for dir in */; do
    if [[ $dir =~ ^[0-9]+/$ ]]; then
        echo "Processing folder: $dir"

        # Create textures folder
        textures_dir="${dir}textures/"
        mkdir -p "$textures_dir"

        # Copy VRM files and convert to GLB
        for vrm_file in "$dir"*.vrm; do
            if [ -f "$vrm_file" ]; then
                glb_file="${textures_dir}$(basename "$vrm_file" .vrm).glb"
                cp "$vrm_file" "$glb_file"

                # Create subfolder in textures folder
                subfolder="${textures_dir}$(basename "$vrm_file" .vrm)/"
                mkdir -p "$subfolder"

                # Convert GLB to GLTF with separate textures
                gltf-pipeline -i "$glb_file" -o "${subfolder}$(basename "$glb_file" .glb).gltf" --separate
            fi
        done

        # Cleanup non-texture files
        if [ "$cleanup" = true ]; then
            find "$textures_dir" -type f \( -name '*.glb' -o -name '*.gltf' -o -name '*.bin' \) -delete
        fi
    fi
done

zip relevant files for retexture artist

find ./ -type f -iname "*2.vrm" -exec dirname {} \; | sort -u | xargs -I {} bash -c 'folder=$(basename {}); filename=$(basename {} .vrm); zip -r "all_folders.zip" "." -i "${folder}/${folder}_attributes.json" -i "${folder}/ref_${folder}.jpg" -i "${folder}/*2.vrm" -i "${folder}/textures/*2/*"'

then make a tmp directory, move the zip to there and extract.

> yes, didn't have to make a zip, fix later

now move hair textures in each folder root directory for convenience like so:

`for i in *; do cd "$i" && mv textures/*/standard_opaque.png . && rm -rf textures && cd ../; done`

ta-da, much easier now
