It’ll all be automatic, with smth like CollisionFidelity to help in cases where the automatic system gets in the way.

How should we make our code not break when this goes live? Is it as simple as doing a pcall on accessing this setting?

If this is lossless, shouldn’t all images be compressed regardless of performance?
If it’s lossy will we have any control over compression intensity to prevent unwanted artifacts?
My concerns about lossy image compression apply to this as well. The game I’ve been working on is dependent on MeshParts, specifically car meshes that effectively replace the character. I’m rather worried the decimations will ruin the aesthetic of the game on mobile/smart toasters. I would really hate to see disproportionately decimated topology as well as incorrect texture mapping following the re-bake or uv approximation required for the textures.

The image quality will not be lossless. We will be exploring how much of an effect this will have. Based on this there is a decision to be made to give developers the ability to override.
I don’t follow your concern around LOD for meshes. The product cases for images vs meshes seem different. In image quality the distance to camera doesn’t matter but in LOD it does. How will having a far away car be of lower detail affect your game negatively?

Hard to say without knowing specifics of how mesh LOD will be implemented, but I could imagine issues with objects that aren’t small at a distance. At 1000 studs away, a car is small and the difference in detail won’t be very noticeable. At 1000 studs away, a planet/space station are still pretty large, and any changes are going to be much more noticeable.

If we can’t override, then I’d rather the image compression only apply to mobile devices. On the big screen, I’d rather have unabridged access to my images. I’m worried about the lossy compression introducing artifacts on natively sized images.
Right now, Roblox images are fuzzy unless they are displayed at the image’s natural resolution. It would be a shame for developers to lose the ability to create crisp images at their natural size as well due to the image itself just being of low quality.
In my game, I always try to upload images at the size I’m going to be displaying them at so that I can have them as crisp as possible. It’s a night and day difference for me, especially on pure white UI icons. It’s important to me that I can continue to display high quality icons in my game after this update.

I’m not sure about release, but they’ve already made one. Check their official forums and you’ll see this option…

…which makes the forum look like this…
You can actually take the CSS file with data-target="desktop" and apply it to the developer forums. The link to the file doesn’t stay updated with Discourse updates, though, and sometimes the CSS file link becomes dead on Discource updates, so using it on the developer forums is a pain (but looks nice!)
it looks like using just desktop_9.css works, so maybe that could work across Discourse updates? It’s worth investigating!

For the short time I messed with my own discourse site, I can confirm Discourse has a built in dark theme. It would need tuning though. The blue logo might have to be replaced with a white on on the dark theme, along with a bunch of other things.

I really hope the Dark-Theme for studio is an actual black and not a blue-black

I am worried about the LOD for meshs in terms of quality. All developers have to compare when we hear Roblox saying LOD, is the current LOD of terrain.
Will mesh LOD be optional or in anyway customizable, such as a number sequence for “camera distance” and “%LOD”?
(Even if instead of connecting the two points at every distance interval, if it was a step graph, that’d be awesome, if not preferable)
Here’s why I’m concerned:
Here’s a mountain close up, the terrain is full detail for the majority of visible terrain
Here’s that same mountain from ~1400 studs away with an FOV of 20
My concerns are not mitigated by:
Roblox Titanic would be significantly negatively impacted by LOD of meshs if it the quality is similar to the terrain LOD. I’m not trying to say that LOD will never be able to help, however I maintain my question from my first paragraph.
Here is a shot at the new ship from~1400 studs away and FOV 20. This new ship model is 95%+ highly optimized mesh parts by inyo22 and mistertitanic44, going into live game soon. Players with a gamepass can fly around and change their FOV, so being far away, then zooming in the FOV, which doesn’t change the camera distance, would magnify the low detail meshs in a negative viewing pleasure way. Here’s current:
If the mesh LOD is any way similar to the terrain LOD, all I can picture the ship being from this far away is a blob and that would be an extremely sad day for Roblox.

This is why we have Camera.Focus – so that you can tell Roblox’s LOD systems where the action is. Most of Roblox’s LOD systems use it instead of the camera’s position.
Off the top of my head, VFX (emitters/trails/beams) are some of the few things that don’t (not sure if this is intended though; if it is, maybe the wiki page should say what all uses it? @zeuxcg @Maximum_ADHD)

As I mentioned before, we’ll likely have something like CollisionFidelity for this - an enum which would allow you to control and/or disable LOD. Mesh LOD can also be more precise that terrain LOD - terrain LOD uses a voxel-based simplification which is absolutely crucial as we can’t precompute much with terrain, whereas mesh LOD would be able to preserve appearance better.
We currently don’t take field of view into account when doing LOD for anything; this hasn’t been a frequent ask. I hear there’s a pipeline to request things like this through though

For Mesh LOD based on quality level, will there be the ability to disable LOD on specific Mesh parts?
Say for example you have a high poly viewmodel gun, and you don’t want LOD to affect it as LOD would be jarring and and unsightly on the gun.

This just popped up in my settings menu
mmmmmmmmmmmm
Edit: It seems that no one else I’ve talked to has gotten this yet, and the icons don’t seem to have changed (which I assume they will once this feature is done, the icons currently used look terrible with a dark theme). I don’t suppose I’m supposed to have this setting yet?

Would this CollisionFidelity include LOD distance? Most games like R6Siege and Fortnite do this and letting a player choose would be nice.

Can confirm I don’t have it with the latest build of Studio
Edit: Can you post screenshots of what it looks like currently? I’d highly appreciate it
