sorry to open a old post im on this problem atm
how can i export an ior map like the one here from substance properly
most of case its gray and uniform and sometimes its dont even make an ior map when i add one to my project
( i add at the end do i have to bake again with ior added in textures set ? when i bake first times it was without ior on white project )
im student and i dont understand the rules 1/ior or (1/RGB Value) x 255 = IOR
i make a moment to understand formula and i can’t get what is rgb value for me itS 3 different number or maybe i have to convert the hexadecimal but i feel its not that ...
i see some project where this fresnel ior map improve great the looking of the pictures...
i use maya/vray
thanks and take care
