Hey y’all, a while back I worked on a little semi-dynamic waterfall function in UE4, & recently I went through and cleaned some stuff up in it & included an example lava river material. It’s free on Github if you’re interested. Cheers!
Distance field intersection glow mask & flow-map stuff:
Depth capture info that helped me fix weird seam-clipping:
Now all we need is sweet charred looking material to match up under it when things pass into the lava to make it look like it flowed over the ground in that spot. This is pretty amazing though I am loving this.
