Bases: Extractor, ColormanagedPyblishPluginMixin
Extract Textures using an output template config.
Note
This Extractor assumes that collect_textureset_images has prepared the relevant export config and has also collected the individual image instances for publishing including its representation. That is why this particular Extractor doesn't specify representations to integrate.
