help with coastal erosion
« on: March 14, 2017, 05:32:19 PM »
Hey friends, I'm current finishing my ISLAND terrain for a UE4 game, and I'm having trouble with the coastline of the terrain. I have already put the coast erosion but the problem is that it doesn't seem to be real because the node by itself made a coastline with no variation and I don't know how to make it more random in terms of size and height(like the GTA V coast for exemple). I have tried this topic reply #5:

"1)Use a simple eroded advanced perlin. Use a preset erosion like flood of slurry, or something, that doesn't have either low or very high sediment carry amount.
2)Mask it using a gaussian mask or something, within the extents.
3)Use Coast erosion masked on the deposition output of erosion. Also make sure you have reduced its hardness using a low-height constant hooked on the hardness input of coast erosion, because even reducing the beach size to the lowest value, it will still be pretty big compared to real world beaches"

It seems to be kind of the result that I want judging by the pictures, but since English it's not my primary language I wasn't able to reproduce it.

Thanks for the attention.
