EDIT: Current progress
Hey, first time being here.
By chance i did a small little holograph shader in Blender (evee) and shared it with a friend.
He recommended me to share this here with you guys.
I have seen some super fancy particle VFX and am amazed by what you can do. I am stuck in the age of vertex colours and simple material blending, so i try to do my best with that.
Here are six polygons, vertex colours and two textures for you. Should run on any potato
This is a viewport grab from Blender 2.8, i hope this counts as realtime, which it is as far as i understand the task here.
