here's the replay link : https://replay.faforever.com/13909802 it generates the right map. I just want to be able to host it.

Flying engi is this working as intended ?)
@Sheikah take a look as well)

Alright I was able to get a version that should increase the variation of the maps a bit. So if you end up playing it let me know how it goes.

I'll bet there's no real difference, in terms of how long it takes to find an opponent, between the mapgen maps and the handmade maps.

that's not true. there's a big difference and that's that there's a big blue dice instead of the map preview picture.

this will disfavor the mapgen in such an experiment. We would need for the preview to show up for others in the game list first, for this to have good results.

@tatsu there is a place to insert the name of a mapgen in the generate map ui.

Screenshot from 2021-02-23 02-12-17.png

when I fill that field in and hit generate I get this :

Screenshot from 2021-02-23 02-11-08.png

doesn't matter what value I put.

the name should be a generated map name like neroxis_map_generator_1.3.5_ie5pi2ly4cy44_aiea_

if you put that in do you get the error?

(yes neroxis_map_generator_1.3.5_ie5pi2ly4cy44_aiea_ works for me)

oh ok I didn't understand that that's how it worked. but then how can I copy a name? FAF doesn't allow copying from any of the places it shows up after the fact

ah goddamit there it is:

I Hope this interaction serves to proove that this is less than intuitive.

I'm still wondering how one would recover a mapname from a replay?


well running FAF from console helps with that

cannot reproduce :

that's water you should be seeing (in fact in your shot you can already tell : the engie's wheels are folded)

Here's as close as I could get in terms of camera angle and time :

It shows up that way for me (and I presume everyone else)

Yeah I still need to add a way to get the info from the replay. Only issue is that the name is not stored in the database so you ahve to download the replay to get it.

Yeap, something wrong with water rendering. Dunno how to debug this.

Checking c:\ProgramData\FAForever\logs\map-generator.logs is probably the easiest way)

Replay is just json it seems:
If y have cygwin/linux:

C:\ProgramData\FAForever\replays>cat SOMENAME.fafreplay | grep -o 'mapname":"[a-z0-9A-Z_\\.]*"'


you can also get the map name for an online replay directly from the java client. click on the replay in question, then click the "download more information" button at the bottom. map name is then displayed in the left panel as "ScenarioFile". Depending on monitor resolution you might need to drag the separator between the columns at the top of this panel to see the full name (hover your mouse to the left of "value" to find this separator). unfortunately there's no easy copy paste.

@biass said in About Neroxis map generator...:

If these generated maps were user made, the community wouldn't even be giving them a chance.

The community has been enjoying custom games on random maps for a while now. The product is already more than good enough for me and a lot of other players, regardless of whatever unforgivable flaws you might find with it. A quick search in the replay vault shows around 30 daily MapGen games. Compare that with ~7 games/day on Adaptive Step Forward, one of M&M Team's Top Picks. Whether or not random maps would be played if they were handmade is not really a constructive hypothetical @biass, the reality is that they are being played more than the vast majority of maps released in the last few years and their popularity continues to grow. All the more reason for veteran map makers like you to bring your experience to bear and help make them even better.


If you really wanted to set up some equivalent comparison for what the "community" wants, you would look at how often the median person plays map gen vs authored maps.

Not how often one, singular map compares to map gen.

I think that is a flawed argument ftx, you can't compare the playtime of every faf map in existence vs map gen which has not seen wide popularity until recently. You should be comparing the average relative quality/enjoyment of playing map gen vs playing a 'standard' map. Playtime=/= fun. Look at dual gap 😄

The point of map gen isn't to have a 'perfect' map, its to have a NEW map, and that is the point I think you are missing. Its really really fun to play something that you and your opponent are completely unfamiliar with, and actually try and figure shit out on the fly. Its not like clicking ladder and finding yourself on daroza's and knowing the first 6 minutes of gameplay require a hard wired build, with at least 10-15 minutes going by before any meaningful player interaction outside of the initial drop to secure expo. At that point it doesn't even feel like playing.

I have played more map gen then ladder this last month, although admittedly it is partly due to the 'look, new!' effect of it. That being said, I would absolutely love for it to be incorporated into ladder. I have had more then 80% of my matches on map gen end up being very enjoyable, which is more then I can say for ladder. And I personally do not see the over-emphasis on map 'aesthetics' to be such a high metric for map quality. But I guess seeing as how you don't actually play ladder maps, you need to evaluate them somehow...

My only complaints with map gen are the following: Terrain isn't always obvious (quick camera angle viewing fixes it) and that after a while (20+ games), some of the maps can seem to be fairly similar. That being said, even for some of the 'similar' maps, I could make the same complaints for a few of the maps I have seen in ladder pool. There is only so much variation you can have imo.

I would really like to see 10-20% of ladder games be map gen for a month, gauge reception then. Its really nice to have something new to play on, rather then the same old same old, and the no build order whoring aspect is amazing.

It gets considered for a matchmaker queue when it meets matchmaker queue standards. This is what I told Sheikah years ago when I started helping him out and it's the standard now. There is no reception to gauge when it doesn't meet the standards of matchmaker.

Flawed argument:

  1. We can compare it over just today. 95-98% of maps will still be authored maps.
  2. I never made this argument, the dude I responded to did. I'm the one trying to showcase that it is a stupid argument, so why you think I'm unaware of this is beyond me.
  3. I gauge relative quality by the matchmaker criteria I have.

Map Gen & BO:
The BO impact is overstated. The thing map gen stops is precise builds built around certain maps where you can quickly snowball into a victory. This means that the people most likely to see an impact from map gen in halting BO gameplay are those at the absolute highest tier of ladder. One could even argue that true BO gameplay is barely even seen outside of tournaments. There are people like Blackheart that just go and play a game on ladder, get Regor, go all in spam down mid, and beat 2200 rated players. Yeah, great BO gameplay there.

Everyone else? Their version of BO gameplay is recognizing where it's important to send engies. Or whether quicker air or more land is more impactful. Or including tree groups in their build. These will all exist in both map gen and in authored maps. Top players themselves barely play ladder enough to recognize the new maps that were in it for 6 months and that I then put into LotS. It's only then that they actually make a BO for it, and then they proceed to forget it after.

Even paradoxically, the dudes complaining about BO gameplay fail to see that map gen maps tend to be the exact sort of setup of BO maps in ladder where you secure middle through efficient early trades and then snowball into victory later. It's just new feature rose glasses.


  1. I don't rate aesthetics for ladder maps, try again.
  2. Aesthetics aren't what holds map gen back from being implemented.

In sum:
Make better posts.

A quick search in the replay vault

This comparison is pretty irrelevant and useless. Dunno why you picked a map at random when you know there are plenty of maps out there that easily make this comparison work in favor of author maps.

You also know there was a tournament going on, and that it would temporarily increase the amount of mapgen maps played.
You even had this part in your post, but edited it out in one of your 28 total edits to this post. Why did you do this?

I know you tried to use a top pick map to increase the relevancy, but server admins have not yet updated to include my new list.
The map you chose isn't actually on my top picks list.

@phong said in About Neroxis map generator...:

You have not said anything to justify why this is not the case. I've highlighted the opinion that a lot of support is based around novelty and the fact that the item is "new" - A basic FAF trend, and that forcing an incomplete product onto the playerbase will end in disaster when the novelty factor wears off. After all, random map generators without a lot of variance will be very similar after a larger number of games played and you start to notice trends. I can make a "map" that is essentially the same as a "tournament" seed mapgen map in about 5 minutes now, I give other players about 2 weeks before they also figure it out.

Don't see how, I contribute to faf by making maps. If I wanted to go and work on code, i'll go and work on my front-end projects that provide more real world value.

This is not me trying to make threats, but if author maps go the way of the dodo, i'll go map somewhere else. I just wouldn't see the point of being here. People will contribute what they choose to contribute, same goes for devs or anyone else.

@Tex said in About Neroxis map generator...:

And I personally do not see the over-emphasis on map 'aesthetics' to be such a high metric for map quality.

I primarily rate asthetics on maps as part of the ladder team.

Map asthetics do not just focus around the specific beauty of a map, but also issues that come from that such as being unable to see ramps, failure to convey important information, etc.

@Tex said in About Neroxis map generator...:

My only complaints with map gen are the following: Terrain isn't always obvious

After downplaying the relevance of the map asthetics rating, you immediately complain about a map asthetics issue.

Without the rating, I could change the lighting on a map in such a way that you literally couldn't see mountains, and not have it be a major impact on the map's overall score. Do you see why asthetics is needed now?

Please do not try and be "superior" about it because you "play" ladder maps.

The word aesthetics is related more to artistic expression/beauty/taste, less so functionality. If I knew you were using aesthetics to mean map readability/ease of comprehension I would not have contradicted myself like you pointed out. Which is why I mentioned it in the closing statement of my post that I found it to be an issue...
