    There are some players which have been banned by Sentinel for using optifine which is allowed mod.Sentinel bans them while using the zoom option(something like 30 fov)
    Today I got kicked for using that and I got Kicked for flying or related and fortunately i got lucky and didn’t get banned.Thats some Sentinel error which I really want to get fixed because not every time you will record and get proof for unban if that happens.
     
  2. Maybe you provide evidence?
    Who is this players?

    As far as I know, Sentinel would be unable to detect zooming in and out, the players you're referring to were likely actually using illegal mods

    It is quite normal for Anti Cheats to false ban/false flag for mods with mechanics like Optifine due to its smoothing of aim, however, it's quite easy to build in a way to stop it from triggering. I would assume that this is not something that has been overlooked in Sentinel, especially as I use Optifine zooming a lot.

    If someone got false banned and they ever so happen to be using Optifine, it doesn't instantly mean Optifine is the root cause of the ban. It could be their weird behavior, maybe they butterfly clicked, or maybe they did cheat.

    Just because someone had a knife in their pocket it doesn't mean they were the one to cut the rope.

    The video you were reffering to was made two years ago. And on top of that, "HetIsAapie" didn't even show his viewers how he got banned, he could actually have been using illegal modifications and just blaming OptiFine for his ban.

    I'd like to link the video but it contains swearing, his YouTube channel has the name "Het Aapje" and Dutch is the language spoken in the video.

    In the video, he claims to not be a hacker but he told his viewers that he used to be a hacker about a year ago. He also claims that it's impossible to remove hacks within an hour, he doesn't show us his .minecraft so he could have just switched his version from a hacked client to an OptiFine client. I do not believe "Het Aapje" at all.

    Definitely don't believe this at all. Modifying the FOV is entirely clientside and you don't even need optifine to achieve an FOV of 30 using the zoom, as you can modify the FOV beyond the limits in the Minecraft settings file.

    Being kicked for flying is usually not Sentinel and is actually Minecraft's built in "allow-flight: false" setting in server configuration files. It's not very reliable as it can kick you for lagging in game because it believes you are flying.

    Recording it will give Loony something to work with. It just telling without any real context except for that you were zooming in probably doesn’t help him.

    Thats true. A couple videos later he gets also banned from hypixel. He has a double clicker and he says he doesn't use it anymore.

    Also if you have proof of you not using any hacks it is a other thing. Zoom is not higher than 30 FOV. It just change your FOV. The only thing i can think is that doing that really fast for a long time can trigger sentinal.

    Optifine zoom is Client-side, so maybe try to record it if it happens.

    Like many people have already said, Optifine's zoom feature is client-side only and will not get you banned on CubeCraft.

    To further expand on what has already been mentioned.
    Client-side modifications (Optifine's Zoom feature) do (should) not relay any packets to the server as it is purely visual, packets go server -> client but not vice versa.
    This would be similar to 5zig's durability feature. Packets are relayed from the server (multiplayer only) to show armour durability, which is then displayed client side. Packets from 5zig's cosmetic nodes don't get passed onto the server (to the best of my knowledge only a couple of the nodes do).

    Optifine is included as standard in a majority of hacked-clients, ghost clients in particular as the zoom feature is very well made. If someone was banned for simply using Optifine zoom, chances are they were using a hacked-client which sent an "illegal packet".

  16. Not going into detail how it works, but OptiFine zoom can certainly 'false flag' some detection methods targeted at killaura and some aimassists.
    Here's an example:

    While killaura and some aimassist modules are being detected by this method, OptiFine zoom is also being detected because of how the check works.

    So if CubeCraft used the same or a similar detection method it could certainly be that players have been falsely banned if they weren't aware of it being able to flag OptiFine zoom.
