Rain fell and the ground did not change: the weather was a curtain of particles in front of a dry valley. u_wet, 0 dry to 1 soaked, does the three things a wet surface does. Darkens the albedo. Drops the roughness hard - which is what makes a soaked meadow read as soaked rather than merely dark, because the sky glances off it. And pools: water finds the low places and flat ground holds what a slope sheds, so the puddle mask is the macro noise the materials already use gated on slope, and a puddle takes the world's up for its normal rather than the ground's relief. It joins the shore's existing wet band rather than fighting it - the same term from a different cause. 34.1% of the frame changes between dry and soaked. GL 7.1 s either way over 400 frames.

Rain that leaves something behind.

Rain fell and the ground did not change: the weather was a curtain of particles in front
|
|
of a dry valley, and a shower was something you waited out rather than something that
|
|
happened to the place.
|

|
|
One scalar, u_wet, 0 dry to 1 soaked, doing the three things a wet surface does. It
|
|
darkens the albedo. It drops the roughness hard, which is what makes a soaked meadow read
|
|
as SOAKED rather than merely dark - the sky glances off it. And it pools: a wet ground
|
|
does not darken evenly, water finds the low places and the flat ground holds what a slope
|
|
sheds, so the puddle mask is the macro noise the materials already use gated on slope,
|
|
and a puddle takes the world's up for its normal rather than the ground's relief.
|
|
|
|
It joins the shore's existing wet band rather than fighting it - the same term, from a
|
|
different cause.
|
|
|
|
Measured: 34.1% of the frame changes between dry and soaked, and no cost - GL 7.1 s
|
|
either way over 400 frames.
