thanks guys, Im work on a Glacier Lake scene.
I have most of the scene completed, and for now, Im trying to optimize it as much as I can.
@fleetwood: I tried that, but in my case the water becomes very noisy, and I need some pebbles visible in shallows. thanks by anyway!
@Dune: thanks for the clear explanation, I know that a Displacement to Scalar is "the way", but I could not make it work... until now. so, lets see what hapend
@KyL: thank you for the link, is very useful, but donst work for me, because Im using a DEM for the terrain, and the merge shader cannot calculate the values correctly.
