Strange terrain lighting bug in studio - weird lines / shadows

[filiptibell]

So this is basically what it looks like:

This just started happening a few minutes ago. It happens when you get close enough to the terrain, once you zoom out it looks pretty much normal, but shadows are gone:

This is the place it happens in: https://www.roblox.com/games/437253984/ALONE-Game

Changing the lighting settings does not affect this at all. Removing the post effects doesn’t change it either.

I’m using a GTX 1070, and this also happens for my friend who has a GT 740.

[Solved] Terrain flickering

I’m drawing a flat plane (nothing underneath it) with smooth terrain and perlin noise, and I keep getting these terrain flickering bugs regardless of the machine I’m on. https://gyazo.com/dffdc2f1fe2aad04dcdf9319e52646d4 Any ideas what’s going on? Edit: This is resolved, found out it was due to floating point errors from the character being so far away from the origin(0,0,0).

The shadow artifacts do look kind of similar yeah, but the pictures above are really close to (0, 0, 0) and it only happens for terrain and not parts

I reverted the place to a version from yesterday - now everything is fine.

EDIT: It appears to be caused by some meshes, when they are added this weird lighting starts to appear.
Importing them into Studio again one by one fixed it.
