[MOD 0.14] Alien Biomes

[Earendel]

So I've been using the beta version the mod you've posted in here and I've noticed severe performance issues. I recently upgraded to a 1080ti so I was really blindsided when I can run Doom at 60fps but not factorio. I think it has to do with the sheer number of decoratives placed by this mod. I didn't have the same issues with my old card, but I also used to run sprite resolution at normal instead of high.

I don't really want to turn down the graphics options, does anyone have any tips to increase performance? I've been getting ~37fps/ups fully zoomed out.

EDIT: nevermind, didn't realize I was two versions behind, getting 60/60 now

I have similar issues with 0.3.8. Zooming out causes my FPS to very quickly drop to under 10, going all the way down to 5 at full view. I'm using a much older card though, a GTX 760, but I get a full 60 FPS when the mod is disabled, regardless of zoom.

Do you get any drops if you use the disable decoratives display option?

I tried to test this again today and for some reason couldn't replicate the lag. It just went away. It's fixed I guess.

Hi, after updating I can't load my 0.15 save: "Reached id limit for noise-layer. The game can't contain more than 255 instances of this prototype due to hardcoded limits of the engine."

Though starting a new game works ok.

Without Alien Biomes enabled the save is loaded with no errors.
I have only Angel Infinite ores mod adding tiles enabled, disabling it doesn't affect things.
Checking "remove obsolete tiles" option doesn't help.

Save: https://www.dropbox.com/s/dqbdw3ik38qt471/u2.zip?dl=1

Please help me otherwise I can't migrate to 0.16...

Noise layers aren't specific to tiles, anything that is autoplaced can have them.
What happens ij you load the save without alien biomes, save that under a new name, activate alien biomes, then load the new save?

[wvlad]

I'll check that.

As I understand there is no way to preserve existing terrain but make it smoothly connect with new areas? So I have to regenerate anyway.

Is there a way to regenerate with more water on existing map? Before update I had much bigger water areas.

[wvlad]

So I tweaked regeneration to not break my buildings with water, feel free to use it in the mod if you decide so.

So disabling-enabling alien biomes worked though I had to regenerate the terrain.

I released a separate mod to adjust water generation in 0.16: https://mods.factorio.com/mod/vlads-sol ... r-like-015

seems not to be compatible with AsphaltRoads mods any more, getting start error:

Error in assignId, tile with name 'Arci-marking-yellow-dl-straight-vertical' does not exists
Source: Arci-marking-yellow-dl-straight-horizontal (tile)

as soon as I disable either mod, it loads fine

[DarkyPupu]

I've an annoying problem, i have (among others ) Alien Biomes, Extra Floors and Asphalt roads installed, which brings me close to the 255 limit (i have 253).

I would like to remove Extra Floors but when i do, i cannot load the save anymore becaure the tiles id go above 255.
On that save, same if i remove Asphalt road or even if i enable the option in alien biomes to remove obsolete tiles.

How can it be that i go above 255 when i remove tiles ?

I didn't try to remove the Alien Biomes mod to not delete all existing chunks parts. I would like to keep AB and remove EF.

Any ideas ?

Yeah that's weird. I think when it does the tile migration phase Factorio tries to load all new and old tiles somehow? I'd call it a Vanilla bug but I'm not sure bug is the right word for it. I haven't checked to see if the devs already have a bug report for it.

Anyway, what I did is remove alien biomes, load the save, save it under a new game, add alien biomes again, reload the new save, regenerate the terrain and endure all the concrete disappearing.

So I tweaked regeneration to not break my buildings with water, feel free to use it in the mod if you decide so.

Would you like to make that into it's own mod with a remote interface? That way Alien Biomes can call the interface and not need it's own code to do that. Ever since I added the regeneration code it's seemed like it would be best as a separate generic terrain regenerator.

Ideally I could make a remote call to get a list of terrain regeneration options, each would return a title and short description so I could add them to an selection interface. Then if one is chosen i call the remote interface to trigger the terrain regeneration, or config popup or whatever the regeneration mod wants to do.

Though I would like to publish it as a seperate mod and help the Factorio community I'm not ready to dedicate time to support it and fix issues.

[DarkyPupu]

I've an annoying problem, i have (among others ) Alien Biomes, Extra Floors and Asphalt roads installed, which brings me close to the 255 limit (i have 253).

I would like to remove Extra Floors but when i do, i cannot load the save anymore becaure the tiles id go above 255.
On that save, same if i remove Asphalt road or even if i enable the option in alien biomes to remove obsolete tiles.

How can it be that i go above 255 when i remove tiles ?

I didn't try to remove the Alien Biomes mod to not delete all existing chunks parts. I would like to keep AB and remove EF.

Any ideas ?

Yeah that's weird. I think when it does the tile migration phase Factorio tries to load all new and old tiles somehow? I'd call it a Vanilla bug but I'm not sure bug is the right word for it. I haven't checked to see if the devs already have a bug report for it.

Anyway, what I did is remove alien biomes, load the save, save it under a new game, add alien biomes again, reload the new save, regenerate the terrain and endure all the concrete disappearing.

Tried to remove alien biomes in the end but didn't change anything, cannot load save still. If i remove *all* the mods, it loads but it's too much of a hassle for still a kind of new game. I'll just restart another save, and try to not get close to the limit (basically it'd be only AB i think)

EDIT :

Found the culprit(s), although not where i expected them. For some reasons if i remove a tile-using mod (AB / Asphalt roads / Extra Floors ...), i need to disable also both of "Angels Smelting" and "Scortched earth". I don't know why, but i guess those two mods do something special regarding tiles management. If i disable both of them, and Extra floors (for example), then it works.

I would like to remove Extra Floors but when i do, i cannot load the save anymore becaure the tiles id go above 255.
How can it be that i go above 255 when i remove tiles ? :?
...
Yeah that's weird. I think when it does the tile migration phase Factorio tries to load all new and old tiles somehow? ...
Anyway, what I did is remove alien biomes, load the save, ...

Although i like the nice Alien Biomes landscapes a lot, i decided to avoid all those problems by (at least temporarily) disabling Alien Biomes. After i did that, i could no longer load my save because i got the message that the ID exceeds the 255 limit. this might have been caused by Alien Biomes no longer "compressing" tiles after removing it, but the migration that removed the Alien Biomes tiles trying to load all the tiles?!
thus: how can i remove alien biomes now ?

since i had already thought about starting over (before going really big on my map, and to have a crazy rail world with ice ore instead of water and no plant life (no forests, no coal, no oil), and with no starting equipment besides a stack of wood and maybe a greenhouse :-) this problem can (for me) be solved easily by starting all over without AB, even when that means that i have a much more boring landscape :-(

[DarkyPupu]

Do you play with AngelSmelting or ScorchedEarth ? If yes try to temporarily disable both, as it was the problem for me.

Hi,

Made a topic on the mod discussion page but just to give a quick tl;dr here. My computer can't really seem to handle the current incarnation of Alien Biomes. Would it be possible for a pared down version of this mod to be made focusing on the more distinct biomes? Akin to the older versions.

Thanks.

[Djohaal]

I can positively report that alien biomes causes stuttering. After lots of exhaustive testing I nailed the cause of an annoying half-second stutter that occurred every few seconds when running to being caused by being present on any alien biomes region. Transitioning to an area with vanilla biomes (or a save exclusively with them) removes the issue, so did removing AB.

Can you clarify a few things?

The half-second stutter sounds like the stutter that happens during new chunk generation. Is the problem worse when you're running off into the wilderness vs running in circles in an explored area while the map has no pollution and no radars? If so, the problem might be because there are more things to place per chunk and chunk generation is taking longer.

When you say transitioning to an area with vanilla biomes makes it better, there actually should be any true vanilla biomes because even the green grass and brown dirt gets replaced with the AB equivalents (even if you don't regenerate the terrain). This might be because deoratives may have been removed in those or because the vanilla decoratives might be there instead. To help narrow that down, did you choose to 'regenerate the terrain' or not. Also if you did, are the improved areas places where you had structures previously or were they empty areas.

Finally, does the problem go away if you use the graphics option to not show decoratives?

The half second stutter occoured even when running in circles or back and forth next to the spawn, no chunks were being generated. It'd start as soon a game started, didn't require building any objects or such.

I found out the vanilla terrain was stutter-free because I downloaded a complex factory save to test if other factors were influencing performance, the large factory on an originally vanilla biome had silky-smooth performance. I didn't regenerate the terrain in said save.

The save being stutter free gave me the hint AB might be the culprit, and indeed removing it fixed the problem in any new maps. I think transitioning into the base biomes also was lag-free but I didn't pay close attention to that component (my original post might have been a little misleading there, I apologize). If you have any map seeds that spawn on grass/brown dirt, I'd be glad to test.

I did not try running AB with the decoratives turned off, if the feedback is relevant I can try running a test tomorrrow and post the results.

[DarkyPupu]

Had to remove alien biomes from server because sadly it's not possible for a friend to even start the game with it (low RAM / 4 Gb). Works fine without AB.
I would like to have like suggested above, maybe a tuned-down version of AB with only most different biomes (no worries if not possible, i imagine it's a hassle to do...)

[FuryoftheStars]

Hi, I've been seeing the half second stutter as well, but I have so many mods running I just attributed it to too many things firing off simultaneously. I just did some testing by turning off Alien Biomes and indeed, the stutter disappears.

In testing, turning off decoratives does reduce the stutter frequency, but it's definitely still present. What really eliminates the stutter, though, is turning the Sprite resolution from High to Normal (even with decoratives on). Obviously I'm trying to overwork (and probably fry) my poor little laptop.

We may just be hitting the limits for the rigs we're running? For comparison, my laptop has an Intel Core i7-4810MQ processor @ 2.8 GHz, 16 GB of RAM, and an nVidia Quadro K3100M (which was not meant for gaming) with 4 GB of VRAM.
