Smooth Terrain decoration visually glitches when loading in

1. grass flickering: there was a refactor that just caused grass to invalidate more than it should. Easy fix, went out already.
2. grass flickering in the fly cam: Fly camera has a bug in it for ever. But we just discovered it. When changing fov the camera focus point (what we base LOD on to put simply) flies around like crazy for couple frames. This was not that visible before our recent terrain meshing updates. Terrain was so slow to respond to this that it did not show. Well not anymore. So fixing bug in camera
3. elongated grass: similar issue as before. It was not that visible before the perf improvements. This is simple integer overflow. We encode grass as int16 to save on memory. For low lod chunks (that are actually large in the area) it could overflow making the grass look extendend

Thank you for the detailed explanation! My theory for the underlaying issue was a process running AFTER the frame was rendered and it caused visual issues since the camera was running on render stepped which typically happens before any physics etc etc.

I will still keep an eye out for this update and let you know how it turns out.

Thanks again for the help!

I believe I am also experiencing something similar to Dan… In my team’s experience Sportv Land [ATUALIZADO 🏄] - Roblox, I usually encounter some parts of the terrain appearing out of the blue, but if I get near to them, they disappear.

At first, I thought it would only be visible on Roblox Studio, however, it is also possible to see in-game:
