I have been using Embergen for about 3 months now and really love the fast iterations and workflow overall.
I was really hoping that you would show your Unreal Master Material, I have seen some mentions of it from another post in June but nothing else. I have setup my own material but it would be super useful to see the motion vector workflow as well seeing if I am missing anything out.
Creating a new UE project and copying EmberGen_Demo_Materials folder to Content folder works fine!
When I copied it to Content folder of an existing project, all the links were broken. It’s a bug in Unreal Engine.
