Making decals reflective

Hi, we want to make a decal shader wherein the reflectivity of the decal can be changed. I’m a newbie to shaders so kindly bear with me.

What’s the best way to do this?

And is there a tutorial on how to manipulate unity shaders that is easy to understand?

thanks

do you own Unity Pro?
without it you can’t do reflections

thanks, dreamora. I don’t have unity pro. Maybe, if I can’t make the decal reflective, I can make it shiny?

can you help me with this? thanks.
