 ## LightFieldConv XML Layout
 
-LightFieldConv was a tool used by Sonic Team to convert Light Field XML data into "binarc" .src files, in preparation for packing the data into a BINA container. The following example XML data can be used to generate an .src file, similar to that which would have been used to create "stg901_lfield.orc" for the test level discovered in Sonic Colors: Ultimate:
