how to make your raygun silver/chrome in blender

 

IMPORTANT TO GO DOWN TO UPDATED TUTORIAL BELOW FIRST AND JUST USE THIS TOP SECTION AS NOTES....
To turn your extruded object to gold. The problem I was having before is that I had no nodes in the shading tab.

So, make sure your shading tab is selected. then select the material icon that looks like globe. and press the box that says ‘use nodes’ on the right side of screen... but make sure your object is selected... i tried to do this tutorial a year later and couldn't figure out why I couldn't find the 'use nodes' box... it was because my model was not selected.....Update.... this wasn't working because the background turned black so gabe hit that circle that looks like bubble and selected Shader editer and did all this from there.
I don't know if the below two lines apply, just go down to updated tutorial.....
 Change base color to yellow. Then adjust your roughness and metallic when the nodes appear
NOTE: MAKE SURE YOU SELECT YOUR OBJECT BEFORE YOU ALOT OF THIS STUFF.
ALSO HIT ALL YOUR TABS AND GLOBE WORLD VIEWS TO SEE DIFFERENT OPTIONS


Updated tutorial:
Im going to change the rings to metal now so first thing is to make sure they are selected.
for metal reflection to work, hit the camera icon....higher above globe and material icons....... switch from evee to cycles.... drop down on right.... evee is poor mans version of cycles. only choose cycles when you want to see what the final version will look like
mess with your roughness, lighting and metalic until it looks right

changing background:
First before all that select world icon for environment( this is only for background editing, it has nothing to do with your model/object), select circle next to color and select environment texture. then click open and select image.
To romove background to see your object by itself, go to dropdown menu and middle left and select world view and detach line from color to color in the nodes

Now I want to add metalic material to the rings around gun. switch back to object mode in the materials and shading...below your main view.
do the same steps as before when you changed to gun metalic, just do one ring at a time, i tried all three before and i had too many programs open so it didn't work. close and re - open your blender file again and close all programs your not using. here are the steps again anyway..... make sure your in object mode in dropdown meny on middle left, select your ring and hit the plus sign and then New, then when nodes appear change color then bring metalic all the way up and turn your roughness down.
