Hello, I have noticed that when exporting to Unity and I set the export option on my character to Merge Material (I use by type), that it does not add an alpha channel to the texture and causes the eyelashes to show up as either white or black in the game engine depending on the character. This is weird because inside Character Creator, as shown in the screenshot, it shows the Opacity map, it just doesn't apply it. I have attached a screenshot showing what it looks like both inside the Unity Editor and inside Character Creator.

It is also worth noting that It works normally / properly when I export without using InstaLOD / Merge Material. So for now, I am exporting twice, then just using the texture from the non-MergeMaterial character.

I am not selecting the embed textures option. I see a texture inside the [model name].fbm folder called "Ga_Skin_Body_Opacity" that has the alpha cutout of the eyelashes, but I believe, to use that, my shader would have to have an alpha cutout texture option which most shaders don't.
