Terrain LOD is slow and choppy looking

This is definitely not just you. I’ve had issues with this as well. I’m having a strange combination of these issues. It’s cost me hours of work.

Uh… not for me. This has been happening to me for a couple of months now.

As you can see, there’s a lot of terrain flickering around through the roads and is showing up where it’s not supposed to.

The terrain LOD also causes the terrain’s geometry to appear way different than what it actually is

When you’re away from it:

When you get closer to it:

This is also happening in my game too, but it’s a lot worse.

Floating patches of terrain and inaccurate geometry

Before:

What it’s supposed to be like (this is when you get close)

In the second video, you can see as I drive around the dynamic LOD looks pretty bad, and there’s a lot of floating patches of terrain/inaccurate geometry appearance

Idk why this happens, but it’s really annoying and it happens to me with pretty much any big terrain map with StreamingEnabled (including mine).

Not sure if it’s my StreamingEnabled settings either, I have 192 target and 1064 max

I’m also playing on max graphics and with Vulkan.

This might be just for me, but if it isn’t, I really hopes this gets fixed, because this has been a problem for me for a while :confused:

It’s a problem in game and in studio. The changes did not fix the issue, at least for me.

what if they made it so if a part is over terrain it won’t load that part of terrain

If LOD was removed it would significantly make performance much lower. Also Roblox focuses on mobile more than pc/console performance.

The problem has ALWAYS existed, but it used to be very noticeably worse. Watch the clip I posted in the first post. The flag fixed the problem described in the post. Marking this as solved.

There’s nothing wrong with this video. LOD has always been visible. Check out the video in the first post.

It’s very noticeable in my game I have to be almost exactly right beside the terrain for it to smooth out.

Incorrect. The quality is still terrible. There was a time where LOD did not effect the game in that big of a difference. Like I said, if you want more info send me a DM, I’ve got a few cases of it documented, that one was just the easiest to tell.


Edit: Let me rephrase that as it came off a bit aggressive. The biggest issue I have noticed with the LOD is when using different materials such as rocks, asphalt, etc., it loads in too slow and doesn’t give details until later. Another huge problem has been with grass decoration. I have screenshots of the grass quite literally being extremely tall or extremely wide. I can provide pictures in DMs (I do not want to leak the map to the public).

I have seen this bug for a few years. It started in around late 2018 and early 2019 for me. I was on a low end laptop and old desktop and when i drove in parts of jailbreak the terrain wouldn’t be fully loaded. It still happens on my newer machine a bit when i first join jailbreak and escape quickly but on lower end hardware it happens A LOT (Last time i used that old desktop was early this year and it still happened and last time I used that low end laptop was a year or two ago since the display broke. I currently have a newer 2020 laptop)

Sadly this issue is still present. Here is a video of it in action in my terrain commission:

The choppiness and slowness of the terrain is unacceptable. Players are going to leave because they see strange looking terrain. I’ve sent the game link so you can check it out if needed.


@ConvexRumbler and any other staff: I’ve enabled freecam for everyone so you can see the issue first hand.

Terrain lod is centered around your player not camera. That is why it does not switch to higher res lod when you fly closer to it

Would it be possible to have it set around the camera, as that is what the player will be seeing anyways? Should I open a Feature Request for this?

It’d be much better for the LoD to be based around the camera for player experience.

Total support. I just released my latest showcase, and I cannot use StreamingEnabled because it needs to be based off the camera. For context, here is the game:

Yes please open feature request.

LOD in general is centered around your camera’s subject. So in the meanwhile, you could code a custom camera with its subject being a transparent part inside it.

Looking for answers as I am encountering this too. <200 studs or less or so is apparently the only option for LOD going on, and its terrible. I can’t seem to find anything to increase the detail further out.
So its being put in as a feature request?

I really wish that the terrain LOD had a much further range at max graphics settings, or at least the ability to customize this. Past a few hundred studs, it starts getting some really horrible breakage, especially with my mountainous areas.

I’m working with a huge map right now (planned size 16000 x 16000) , and this is just a section of it, I think 3000x1500. I’m extremely worried about how combat is going to end up when the game is absolutely decimated at a distance you will still be able to see. I haven’t added buildings/vegetation that will obstruct the view a bit more, but it’s kind of pathetic how it looks right now.

I agree. Especially at high speeds, I see a few polygons of the terrain stretch cause of the LOD trying to load in quickly when. Once I saw a huge single polygon over me. It’s extremely distracting.
You can do this by going in driving simulator and driving quickly where there’s terrain, or just generate a lot of terrain and run extremely quickly. Here’s a picture of what I mean

You can even see the terrain creeping on the road due to the LODS, and at the back it basically ate it. I hope the new terrain LODS said on the roadmap fixes all the issues with it and make it less noticeable when it updates, it’s really distracting.

Exactly. There’s always those weird chunks, and it happens to every game (I think only the ones with StreamingEnabled) with a decently sized map and terrain, caused by moving at a high speed. I really hope this gets fixed, it’s annoying and distracting
