When I use a Wardrobe Item that applies a Head Hidden Face Map, it works fine within the MetaHuman Creator. But once I assemble the character, the Head Hidden Face Map seems to be completely ignored, while the Body Hidden Face Map works everytime. I’m using 5.7 and I can’t find anything on this issue… besides turning off Substrate and Virtual Textures in the Project Settings, which did nothing.
Has anyone seen this?
I have the same issue in 5.8
Same problem faced today, is very frustrating for it still exists even past so many months…
Hey! @chinohead
I think the issue is a common one in how meta human material instances and dynamic parameters have opacity/hidden face masks during assembly or at run time.
Some things I would suggest looking into or trying are
Check the Material Instance Override
Open the face material instance (MI_Face or similar) generated for your MetaHuman in UE.
Check the material parameters for the Hidden Face Map texture parameter under the Material Parameters. It’s possible the Wardrobe Item pipeline does not automatically bind/pass this texture parameter into the parent material instance upon assembly, be sure to have the texture BBM_Face assigned directly there, and that the scalar toggle for using the mask is set to 1.0.
Verify Opacity / Masked Mode Settings
Ensure that the Face Material is set to support Opacity/Masking (or standard Masked blend mode if not using Substrate for forced opacity). If the Substrate was recently toggled on/off in Project Settings, be mindful that you had to restart the editor completely as Substrate material shaders oftentimes have issues with compiling the opacity/transparency masks properly otherwise
Check the Blueprint Logic / Construction Script
Check if in you BP_MetaHuman there is any script that set dynamic material parameters on BeginPlay or Construction. It’s possible that some default script reset material parameters of the Face mesh, overriding what you have set in the Wardrobe asset
Re-bake / Refresh Textures
In the MetaHuman Character Assembly window perhaps try a Refresh of the Face Material Baking Options or a re-export of the character assembly to rebuild the texture parameters
Could you let me know if you’re assembling this in purely editor or at run-time via Blueprint? And if you look at the MI_Face material instance directly, is the Head Hidden Face Map slot filled or empty?
This will help determine if it’s a baking pass problem or a shader assignment issue.

Hi, can you help me here in my Wardrobe item there is only one Body Hidden Face Map Texture slot and you have two slots one for Face Map too.. how i will turn on Face Map Texture slot in my Metahuman Wardrobe Item? i am using UE 5.6 ..many thanks
Hey @FireCG136
I think I know what’s going on here… The root cause for you only seeing the Body Hidden Face Map Texture slot and not the Head one likely has to do with two things: the specific pipeline your Wardrobe asset is using and the version differences in MetaHuman Creator/Unreal Engine (as 5.6 vs newer versions updated how outfit pipelines expose texture slots)
Here are a couple of things we could try to get that Head slot showing up;
Check the Outfit Pipeline Assignment
In your Wardrobe Data Asset (Details panel) check the Pipeline section. Make sure that the Editor Pipeline is set to either MetaHuman Outfit Editor Pipeline (or the specific head/outfit pipeline asset provided by the MetaHuman plugin) instead of a generic body pipeline.
Usually changing this parameter to the correct one will enable the missing Head texture parameters in the Details UI
Verify Asset Class & Target Mesh
Check if your asset is purely classified as a Body Clothing item or a Head/Accessory item (hood or hat)
In UE 5.6 if your item is purely classified as a body clothing sometimes the system defaults out the Head texture slot.
You might have to duplicate or assign the pipeline that targets the Face/Head component.
Manual Parameter Override in the Material Instance
If the Wardrobe Item details panel still won’t show the slot you can usually bypass this by opening the actual Material Instance applied to your item or character’s head/face.
Look for the Head Hidden Face Map parameter inside the Material Instance directly and enable the texture slot manually.
If you’re still having an issue, Could you share what asset class or pipeline preset your Wardrobe item is currently using?
Also let me know if this is a custom FBX asset you imported or a modified preset from MetaHuman Creator
