At the moment I'm finishing up a a terrain material, this is the first time I've really used all of Unreals material features Is this too extensive?, what kind of strain will it put on the engine? It serves around 6 terrain variations, should I be splitting it up between multiple materials?
You measure it not by a spaghetti length but the number of the calculations: please make a screenshot of the instructions (stats). + you could post material in full resolution
