tk-config-default2\core\templates.yml has common path definitions.
For example :
nuke_shot_render_stereo:
definition: ‘@shot_root/work/images/{name}/v{version}/{width}x{height}/{Shot}{name}{nuke.output}{eye}v{version}.{SEQ}.exr’
nuke_shot_render_pub_stereo:
definition: '@shot_root/publish/elements/{name}/v{version}/{width}x{height}/{Shot}{name}{nuke.output}_{eye}_v{version}.{SEQ}.exr’
Question is, what shotgun app / api is responsible to use this yml and convert it to useful paths. ?
