When exporting characters from Daz to CC3 via the Transformer, only one of the two maps will be exported. Both Normal and Bump are used in different ways - normal to create the general position, and bump for the secondary and micro details. It would be awesome to have both exported - at least when having both in the config file. Having them in the BakeTexture-folder wouldn't be an issue.
Having a separate tool where you can drag Daz-maps in, and retarget based on the CC3 maps (head/body/arm/leg etc) to do it outside of the transform - this would make it a lot easier to work with all the different map types in Daz, and all the varieties of makeup/beards.
