====== Blender Object Opacity ======

==== How to make blender objects disappear, fade in and out on screen====

This may not work in every case because of the nature of materials and rendering but there is a way to make it work with the Principled BSDF shader at least. 

  * After setting color of the object in principled shader...
  * Shader Tab > Settings Panel > Change blend mode to Alpha Blend instead of Opaque
  * Uncheck Show Backface (by default this gets checked (annoying) when you change to Alpha Blend
  * In principled shader change alpha to anything other than 1 (change to zero for complete transparency)
  * In Eevee, you will see the result on screen instantly.
  * If the object has multiple material colors, you will need to repeat those steps for all materials
  * If the fade in and out is part of the animation, you'll need to keyframe the alpha settings
