6L6 G Vacuum Tube Render

I wanted to see if I could create a realistic vacuum tube in Blender. This was a learning experience. From learning how to make custom shaders and painting the silver getter deposit on the inside of the glass, to modeling the shapes of the plates and the spiral helix for the grid, and finally animating the output of the filament and cathode black body emission shaders over time to simulate the heating up of the cathode.
Modeling made easier by realtime rendering on RTX3090.
