I am trying to change the opacity or alpha of an object so its see-through in 2.8. How do I do this? I can't seem to get to figure out how in 2.8. Example of what I am trying to do is below.
The setup is very basic. One thing to note is that I've used Wireframe modifier with second material.
Just a mix between Transparent and Emission which is added for colorization and "nicer" visibility.
First slot is above material for transparent object, second is for wireframe.
Most important thing here is to set Blend Mode Type as Alpha Blend.
In Wireframe modifier set Material offset to 1 to be able to use material from second slot. Also set wireframe Offset to -1. It will hide wireframe object in main object.
