Need HELP with keyshot

[jasmehar]

Hi!
This is my first time posting here, I am a beginer in keyshot and currently working on a lighting project. Unfortunately, I am having so much trouble with rendering light reflections. Ill really appreciate if anyone can help please

this is a light, (first with light on and second with light off) and upper part is a sheet metal folded part with crinkled texture on the inside, it also has an led light on the bottom of the metal part on the inside. when I add the led light on the bottom part it doesnt give out the crinkled texture reflection that i want, for example look at the lit product, the reflection is plain whereas I want it to be textured. Can anyone please guide me how to give a crinkled texture or any similar texture to the reflection on the base and ground plane of this lamp.
Thank you
