The HMD panel controls the Helm Mount Dispay System and is used only in the MLU version of the F16. The HMD System is a night vision camera on the top of the pilot helmet controlling the Brightness and Contrast of the Video displayed, also the visor's symbology intensity and radio transmission. The HMD panel is located in the lower part of the Left Auxiliary console.
The model was created in Blender 2.81 for the Cycles engine, the textures and materials are PBR based. The model has been rigged with a simple Empty for easy animation.
NOTE: I tried to keep all the materials packed within the .blend but if for some reason it is not here, you can find them on the Texture folder in the .zip file that accompanies this panel or if you still require it, don't hesitate in contacting me. Also as you can see in the thumbs it can be printed as separate parts for your sim, it's as close to the real one so scale is close to 1:1
