Panels with buttons and levers and such.
Use it in industrial settings, spaceships, laboratories, you name it...
Groups are preserved in FBX file so you can move stuff around, texture easier, and customize.
I used basic materials in my renders, so use it as a reference only. Make your own for better results.
However, if you want the images I used on the display screens as seen in these product renders, just msg me and I'll send to you.
Enjoy!
