Problem with Glass table. 2 textures for 1 object?

Hello, I am trying to create my first glass table. I have watched several videos, read several forums and yet I have not found an explanation for my problem.



So for a glass table, I know there are 5 textures. 2xDiffuse, 1xNormal and 2xSpecular. I tried to make the glass top and the wooden legs separately but the visual effect in s4studio is never the same as in subsance painter. For objects without glass I am able to make a good rendering but because of the glass, I cannot do it.



I'm getting a little lost in all the textures mentioned before in sims4studio. Could someone explain to me more precisely how to make 2x diffuse, 2xspecular for a single object? I'm really stuck and I've already tried lots of things but nothing works.

thank you.
