Transparent Character Mesh

Hello, so i have a question, im probably missing something simple…

i created a primalitem costume for the carno, using the skeleton costume as a base, my goal is to have the original charactermesh (any player who has color bred carno) transparent, and to have the skeleton mesh applied beneath it like an Xray perspective… i got both Mesh to display,alpha is 255 on both, cant see the skeleton through the original mesh… anyone know how to tweak the character mesh down to like 170 or something instead of totally opaque?

I believe you would have to modify the materials on that mesh and alter their opacity values there.
