Hey all,

I've been racking my head trying to sort out a problem i've been having with my current hair creation pipeline. Currently as it stands my pipeline is as follows;

Create hair stands in Fibershop -
Create hair using cards with Blender Hair Tool -
Importing final merged  FBX into Character Creator 4.11 -
Edit hair settings (lighting, shading etc) and turn into a character Hair piece using CC's 'Create Hair' function-
Import into Unity (2021.3.5f1) using the URP 1.3.9 importer.

My current problem with this pipeline is that right at the last hurdle.

When importing the character from CC4 into Unity using the importer tool, no matter how many different settings I try, I cannot get the hair meshes/materials to appear on the importers list of included meshes/materials. This function works fine when the hair is set to say an accessory, but as soon as I change it into a Hair Piece and import it again into unity, the hair piece and accompanying meshes/materials disappear from the list and i'm stuck having to remake the materials again inside unity, thus undoing most of the importers time saving features.

I've tested it by just downloading some generic rigs/hair pieces from inside CC4's hub, exporting them and then bringing them into unity using import tool and the hair that is marked as a 'hair piece' appears in the list no problem while my custom mesh vanishes. Is it something to do with it being a custom hair piece, maybe perhaps some setting I've failed to apply somewhere? I really have no clue! 

If anyone has any idea, please let me know! 
Cheers
