I still had them saved in my tabs so here you go: this playlist was extremely helpful when it comes to learning about Render Textures in Unreal (specifically the Unreal Live Training, I worked with similar systems to the one used in this game jam before so I wasn't entirely new to the set-up but skipping through the playlist helped a lot), this video shows how the system is used for a dynamic landscape, and finally, similar to the last one, this video except with a method that is a bit easier to set-up (which works incredibly well in UE4 but has some issues in 5 when it comes to height displaced Landscape and since I wanted to keep my options open I opted for the other method).
