Collada Model cleanup scripts

This resource is a follow up to my previous forum post, to address the NaN issues and other warning messages when using the stock assets.

Since the Collada files are simple XML format, it just requires a few edits to resolve the common issues. Besides NaN warnings, most art I've found also has hard coded paths to the source textures. When imported it to T3D, it causes failures until we open it in the Editor and correct the materials manually.

In fact, I've found that by editing the Collada files by hand -- its easily possible to correct the names used by the images for textures. In some cases this is required, like if they start the texture name with a number or include special characters in its name.

First, I wanted to eliminate any of the NaN warning messages. While just a warning, it was unnecessary clutter.

I placed this script in my cygwin home directory and called it simply: fixNaN

SEARCH="NaN"
echo "searching all DAE files for: ${SEARCH}"

#build file list
find . -name "*.dae" -print > file.list
find . -name "*.DAE" -print >> file.list

for FILE in `cat file.list`;
 do
  test=`grep ${SEARCH} $FILE | wc -l`;
  if [ $test -gt 0 ]; then
   printf "$FILE : $test issues found";
   sed -i 's/NaN/0/g' $FILE
   echo "... corrected $FILE"
  else
   echo "       $FILE ok"
  fi
 done

To use it

I cd into my game/art directory (under projects or simply the template)
and then run it as:

~/fixNaN

(I chopped 90% of the output, to reduce clutter on this page ... but hopefully you get the idea)

Next, I created a similar script for the hard coded texture path and extensions.

I also placed it in my cygwin home directory and called this one: fixIt

if [ $# -ne 1 ]; then
  echo "ex. [[6288105ea991e]] String_to_remove"
  exit
fi

SEARCH=
echo "searching all DAE files for: $SEARCH "

#build file list
find . -name "*.dae" -print > file.list
find . -name "*.DAE" -print >> file.list

for FILE in `cat file.list`;
 do
  test=`grep ${SEARCH} $FILE | wc -l`;
  if [ $test -gt 0 ]; then
   echo "$FILE : $test issues found";
   cat $FILE | grep -v "${SEARCH}" > temp.$$
   mv temp.$$ $FILE
   echo "... corrected $FILE"
  else
   echo "       $FILE ok"
  fi
 done

To use this script requires passing a parameter.

Here are the (2) examples I use, to correct the hard coded paths and such.

~/fixIt "file:"
~/fixIt "\.psd"

Together that seems to clear up all the issues and spam I had come across.

And if you come up with a better solution, please let me know!

p.s. if you aren't google savvy ... let me help with the location of cygwin;
www.cygwin.com/

It downloads an installer, which then lets you select packages to download, etc.
For this effort the defaults are ok, just need to get a cygwin prompt.
