Note: Make sure to leave "Double Sided" turned on when deriving. This will make sure the nails are visible from both sides. When using semi-transparent opacity, make sure the Transparency "Mode" is set to "Composite Blend". "Alpha" (the default) only allows pixels to be either fully opaque or transparent.
It is recommended to stick with the original UV map sizes. If product size becomes too large, try reducing the scale of the texture images. (Ex. From 512x512 to 256x256; from 256x256 to 128x128)
