Adding the asset in Blender is highly recommended. (for parenting the outfit armature, and also making shape keys to shrink some parts of your own Mamagen for better fitting/less clipping)
The Unity Package comes with 14 total preset materials for each swimsuit to swap the colours and designs!
The prefabs has basic VRCFury setup! It will now automatically link to your avatar's armature and add a toggle in your menu. (The pregnancy growth slider doesn't work perfectly, it only has basic blendshape link. You will have to manually set up the swimsuit to work with the animation, check the PDF for more info.)
The pregnant version is a completely separate mesh because it has different weight paints, though both versions have a pregnant blendshape for customization purposes.
The pregnant swimsuit textures are set up in a specific way in Substance Painter so you can effeciently match the textures from the regular swimsuit. (Check PDF for more info)
This product DOES NOT include the Mamagen base itself!

Requirements:
Poiyomi 8.1 shader or newer.
