you can name it anything but i personally name it "THE ENTITY"

heres the most important part. the color, you should use noise or else it wouldnt look good.
also for the colors select the box and paste this number in it all 3 of them (make sure to empty out the previous number) 340282356779733642999999999999999999999 then it will look like this.

here is where you have most freedom. but i recommend using
1
1
1
2.5
2.5
0
2.5
2.5
0
so it looks better.
