Thanks for your response, I was originally thinking that some kind of high density voxel-based geometry would be ideal actually, however I was unaware that you could do that kind of thing in Unreal Engine.
I saw someone mention something similar in this question, however the link in the response doesn’t work for me:
Also when I search for “voxel based geometry unreal engine” or similar search terms all I get is stuff about Voxel Cone Tracing.
If you have any idea of how to get voxel based geometry in Unreal Engine 4 please let me know, or if someone could at least point me in the right direction it would really help me out
