How to make a translucent material shiny?

So the title says it all. How do I make a material I set as translucent to be shiny?

What I am attempting to make is a balloon. I figured it would be as easy as setting it translucent, setting the colour, the opacity, refraction and the roughness.
well everything went well except the roughness, it doesn’t seem to do anything.

I checked out the glass material, but it didn’t help me at all.

Anyone know how to accomplish this?

EDIT: well I finally manage to get it shiny. I set Translucency Lighting Mode to TLM Surface. Unfortunately it is now shiny like glass which is far too shiny (Roughness of 0 seems to be the only value to give it any shine at all.)

Here is an image of what I got

there is a example for a soap-bubble somewhere. maybe you try to archieve this? look for it’s parameters to solve youre problem.
