Hi, I'd like to know how to export a minetest 3D model to b3d. |
| 13:09 |
Krock |
Furi0us_mat: let's move to #minetest. This channel is mainly for the engine side of things, and less so for modding questions. |

<warr1024> I'm trying to debug paroxysmal severe performance degradation that started after the 5.9 upgrade. After some number of hours of uptime, the server will just get shitty and lag will go all over the place. |
| 14:13 |
MTDiscord |
<warr1024> I can run MT under perf and it looks like it will generate at least 2GB of data per day. Is there some way that I can crop these files down or something such that it covers only the critical portion? |
| 14:13 |
sfan5 |
it sounds like the performance degradation is omnipresent |
| 14:14 |
sfan5 |
right? |
| 14:14 |
MTDiscord |
<warr1024> I've heard a lot of anecdotal reports of poor peformance on 5.9 but it's very hard to get much rigor on it. |
| 14:15 |
MTDiscord |
<warr1024> In my case, on my server, I may be seeing SOME performance loss most of the time, I guess, but I'm mostly concerned with the parts where the server becomes suddenly completely unplayable. |
| 14:15 |
MTDiscord |
<warr1024> I'm running a very lag-tolerant game, and players are also used to lag "weather" that's affected by things like background backup jobs and variable player traffic. |
| 14:15 |
MTDiscord |
<warr1024> If you think that a trace during a non-meltdown period would be useful too, I suppose I could submit one. |
| 14:16 |
MTDiscord |
<warr1024> There seems to be something going on though that's NOT in the main lua thread, as my attempt to dig something out with jitprofiler turned up nothing of interest, and that also tends to capture a lot of calls into the engine by mods. |
| 14:16 |
MTDiscord |
<warr1024> It looks like whatever is going on is outside of env step |
| 14:18 |
sfan5 |
what I was trying to say is: if the lag starts happening after 2 hours then you can just attach perf for 5 minutes at that point and likely get good data |
| 14:20 |
MTDiscord |
<warr1024> I suppose I could try that. I'd have to do some funky manual shit then I guess |
| 14:20 |
sfan5 |
https://github.com/minetest/minetest/blob/master/doc/developing/misc.md#remote-profiling |
| 14:22 |
MTDiscord |
<warr1024> I'll give it a go. I'm not sure if the container has enough tools to do it, but I assume just having perf in there and a RelWithDebInfo MT server running should be enough ... |
| 14:22 |
Furi0us_mat |
speaking of minetest 5.9, one thing has appeared in my game folders: a certain folder named mod_data has appeared, what's it for? |
| 14:23 |
MTDiscord |
<warr1024> it's for the new mod data feature, for cross-world mod-specfic data |

<luatic> will have to look into the CI failure. there's also something about the way irrlicht does materials which we haven't properly taken into account yet. |
| 17:02 |
MTDiscord |
<luatic> we might also want to support something like float frames for gltf (since there you usually have timestamps in seconds rather than frames). |

<wsor4035> aha, ive found comments here that are similar, but no one made an issue yet that i can see |

sfan5 |
this is not a reproduction, just a proof |
| 17:23 |
MTDiscord |
<wsor4035> see the updated comment |
| 17:23 |
Krock |
is it reproducible with the Mesa software renderer? |
| 17:24 |
sfan5 |
if it happened in singleplayer that'd be helpful |
| 17:24 |
MTDiscord |
<wsor4035> working on seeing if i can make a minimal reproducable example. ideally with void+adv trains |
| 17:24 |
Desour |
it's interesting how the water gets more opaque, as if some faces' tiles were moved |
| 17:25 |
Desour |
don't forget to test with default settings |

transparency sorting issue? |

<wsor4035> just to be sure, i compiled the server on stable-5 branch (5.9 releases) and the issue still occurs |

<wsor4035> interesting, short of using the same map locally, build some sections of track in single player, same game and advtrains mod and i cant replicate |
| 17:59 |
MTDiscord |
<wsor4035> disabling shaders appears to solve the issue, at least i cant replicate with them off |

btw you can use local map saving to grab a copy of the server map to check locally |
| 18:10 |
|
SFENCE joined #minetest-dev |
| 18:10 |
MTDiscord |
<wsor4035> probably faster than me downloading the whole map from the server |
| 18:15 |
MTDiscord |
<wsor4035> ok, yeah, i can replicate it locally with locally map saving a part of it |
| 18:19 |
MTDiscord |
<wsor4035> added that to the issue if anyone wants it |

What about turning off post processing? |
| 18:39 |
MTDiscord |
<wsor4035> it flickered a few times (locally) with it disabled on start up, and then i havent been able to trigger it since |
| 18:40 |
MTDiscord |
<wsor4035> on the server with post processing off i cant seem to trigger it |
| 18:40 |
MTDiscord |
<herowl> the flickering looks like occlusion culling failure, why would postproc have anything to do with it? hmm |
| 18:40 |
MTDiscord |
<herowl> anyway |
| 18:40 |
MTDiscord |
<herowl> what's the reason why macos 10.14 is required by MTE? |
| 18:41 |
MTDiscord |
<herowl> supposedly devices with intel CPUs (so before M1) can't update to it without some deep patching |
| 18:41 |
MTDiscord |
<herowl> (I'm writing it after reports from some community members on the VL discord) |
| 18:42 |
sfan5 |
we don't have a mac maintainer so this question has no answer |
| 18:43 |
MTDiscord |
<wsor4035> ok, so it looks like post processing off doesnt have an effect, restart the client and can replicate the glitches |
| 18:43 |
MTDiscord |
<wsor4035> it seems the only "fix" that works so far is to turn shaders off |
| 18:43 |
sfan5 |
a cursory google search shows that apple still supports intel macs even with as new as macos 14 |
| 18:44 |
sfan5 |
10.14 is already long out of support and from 2018. did you confuse it with something else? |

lib/gmp/mini-gmp.c is likely to break again on the next update but whatever ¯\_(ツ)_/¯ |

that is: its formatting. |
| 19:14 |

<luatic> it's failing because of trailing whitespace on "doc/lua_api.md:8955:Used by minetest.register_entity. " 🙃 |

<luatic> 👍 feel free to push the trivial fix straight to master. the trailing whitespace was introduced recently in ea96f6e, you probably started your PR before that, hence leading to no CI failure on your PR. |
| 19:18 |
MTDiscord |
<luatic> i'd recommend rebasing on master before merging PRs that are related to CI. |

I just want to check the CI again with my PR. |

Yes sorry about this I didn't think anyone would create more whitespace problems in the meantime ... |

help! i'm always getting connection timed out when connecting to a server now. the password check still worked. others are logged in. other servers (with older versions) work |
| 20:42 |
MTDiscord |
<exe_virus> hurm. So they are on 5.9 and you are on 5.9 or? |
| 20:42 |
Sokomine |
the switch to 5.9 was planned but iirc stopped due to connection problems |
| 20:43 |
Sokomine |
i now compiled latest git. no chance. not even with an older mt binary from july |
| 20:43 |
MTDiscord |
<exe_virus> so you are on 5.10 and they are on 5.? |
| 20:43 |
Sokomine |
got Irrlicht: SDL_PollEvent took too long: 15ms in verbose |
| 20:44 |
Sokomine |
admittedly the server is under high load. lots of monsters, people fighting them right now. an important event going on. so more load than usual. but others report no connection problems |
| 20:45 |
Sokomine |
servers' on 5.8.0 and i just compiled latest git. with the version from yesterday i get the timeouts, and even with one from july |
| 20:50 |
MTDiscord |
<exe_virus> could be something specific to client side changes then |
| 20:51 |
Sokomine |
an older binary alone does not help |
| 20:52 |
MTDiscord |
<exe_virus> wait, you can't connect from like 5.7? |
| 20:54 |
MTDiscord |
<luatic> Sokomine: see #14765 |
| 20:54 |
ShadowBot |
https://github.com/minetest/minetest/issues/14765 -- New 5.9.0-dev networking is not allowing legitimate players to connect under some rare circumstances |
| 20:55 |
Sokomine |
i don't remember when 5.7 was current. i'm copying the entire folder of a year old version now and hope to have luck with that! |
| 21:00 |
sfan5 |
as far as I'm aware the problem is with 5.9 on servers, client version not relevant |
| 21:05 |
Sokomine |
i've heard that as well. i had trouble logging into that server on 5.8.0 in the pasth weeks/months - often took 3-5 attempts to log in |
| 21:06 |
Sokomine |
my connection is still very low bandwidth if that info helps (1 mbit)) |
| 21:06 |
Sokomine |
now i get invalid password messages. either i can't type anymore or i mistyped too hoften in previous failed attempts to connect |
| 21:13 |
sfan5 |
seems likely to me that the network code does not appropriately respond to congestion and this was not noticed because it ignored packet loss previously |
| 21:17 |
Sokomine |
that could be |
| 21:19 |
Sokomine |
packet loss is unavoidable in some places. the server spams poor clients with packages due to mods changing the world too frequently in some places. or other not yet discovered bugs. there has to be a reason why server spawns become imberable after a while. i can go to view range 400 almost everywhere - but at server spawn on yl - 20 view range isn't enough for the packages to squeeze through an |
| 21:19 |
Sokomine |
1mbit line. and that's with mesecons forbidden in that area |
| 21:21 |
Sokomine |
even back in the old times vanessaes' survival server suffered from that and i could no longer go there. back then it was probably my computer too slow. but that no longer is an issue |
| 21:23 |
Sokomine |
in the current case, there's a big fight going on on the server. many of those ~33 players reportedly online will have joined. there are very likely several hundred of mobs_redo stone monsters and the like trying to kill those players |
| 21:24 |
Sokomine |
last time i checked movement code meant one package per entity changing direction? quite a lot of packages |
| 21:27 |
MTDiscord |
<exe_virus> yeah it's a huge amount of packets and operations when you have collisions and big fights, literally working on optimizing that right now for 5.10 fingers crossed it gets in and works flawlessly |
| 21:28 |
Sokomine |
aah! good |
| 21:28 |
Sokomine |
if you want to see such a thing in action and see why it is important (helps to raise motivation - at least for me - if i see people using my code. perhaps you feel similar :-)): there's a huge fight going on on the your land server. hundreds of entities attacking players |
| 21:34 |
MTDiscord |
<exe_virus> right, that is what I'm testing, don't worry I just register half my mob monster as NPC and half as Monster and they battle each other. I am working with ~1000 with essentially max health, trying to get that better is my 5.10/5.11 goal |
| 21:35 |
MTDiscord |
<bastrabun> YL will profit a lot from this snippet and we'll gladly test 😉 |
| 21:35 |
Sokomine |
good :-) |
| 21:36 |
Sokomine |
but by all means feel free to take a look :-) it's probably very chaotic. but there on yl you can see it live now how it's now - with actual players adding to the chaos :-) |
| 21:37 |
MTDiscord |
<exe_virus> well aware, I'll be pining when this rework is done, red-001 had some good points to improve it. |
