Anyone else having problems with water glitching?
Standing by the water side, random large waves suddenly glitch into view, then disappear in an instant. About 300ms maybe? The water also moves about 5ft onshore, then off again in the same amount of time. Most noticable when at the shoreline, but also noticable when treading water. I have a video but probably too large to upload.
I wish it was like that. These are in and out in 1/4second, like a glitch in the wave animations. Just sit by the shoreline for 5 seconds and they will come. At least for me.
This is slowed down a bit. All over in 1/3 second. It’s every 5 or 10 seconds - the whole sea glitches like this. Kinda ruins any worls with water.
Removed mods, but no difference.
I’ll see if anybody else gets them before doing whatever steps I need to stop it. But I’d rather not waste my time. Remove mods, clear shadercaches, turn down settings to low, restart pc and hope for the best?
Crazy stuff
Looks like the wave is deforming down below the terrain. The water polygons probably extend under the terrain a good bit to keep from separating from the terrain at the edge (which would be ugly). So when the sine wave moves through the vertices, and there is a shallow grade on the terrain, the water vertices move below the terrain causing that effect. This gets weirder when the wave crest pokes above the terrain when the waves are spikey:
/\ /\ water above terrain
--------------------- terrain
\/ \/ water below terrain
Usually there is dampening applied to the deformer as it gets closer to the edge of the water polygon strips. But as I said, if the water extends well into the terrain, the dampening wouldn’t have an effect on the troubled portion.
At least that’s what I think. XD
Moved to its own topic. I will jump in tomorrow and see if I am having this issue too
Well ok…
@BoomstickJoe I thought maybe you were onto something. The worlds I’ve been on have very wide, but shallow lakes. But I’ve just landed on a small island within a sea region of a frozen world. One edge of this island drops straight down into the sea. No shallows. It’s still doing it, not as noticable, but the whole ocean seems to glitch.
It’s doing it every 5 to 10 seconds, on all lakes, and the effect is random. Sometimes the land is shown, other times a huge but singular wave appears for 250ms. One wave was big enough to pick me up, briefly. Filled the whole screen for 10 frames, then disappeared. Sometimes a huge single wave appears on the left, sometimes the right. It happens on every small lake/pond/large puddle I investigate.
What is the accepted video size on here? 500+Mb is probably too much, huh?
I’ve tried to fix it by pulling various levers IYSWIM but nothing helped. Also, it’s not done it until the recent update (i think whichever update fixed the plant life underwater moving around at certain angles of approach).
Also, waiting by the shoreline, I see random spikes in the waters edge, suddenly growing and shrinking back to the normal pattern. Oh, maybe I’m going mad? Too much time spent looking over the lake. That’s probably it.
So, MS make video editing software, and it seems to actually work. Amazing. Anyway…
In an effort to rule out any other possibilities for strangeness, have you tried clearing your shader cache (if on PC) and see if the water is still being funky? I know theres a lot more going on with the water physics than a bunch of fancy shaders, sine wave deformation mostly, but I’ve found clearing it and letting it rebuild on a boot up has fixed many visual silliness like this.
Tried deleting steam cache, nvidia cache (DXCache/GLCache). Don’t know if there are any others. But it made no difference. But it seems like it’s only me… 
(yes, sent bug report to NMS).
