Artificial Undergound Mushroom Biome

[Lushros Dofine]

I have a question about making one. The main thing is, can I create an undergound mushroom biome in the Undergound Snow? I have all the basics down, including being just below 0 depth and having more than one hundred mushroom grass tiles. But so far, I don't see any changes to music or background. Is this normal for an artificial biome in the Undergound Snow? Or do I need to move it away from the Snow Biome?

Are you getting any mushrooms?

Also, 0 ft or just befow that might not be enough. I think the snow biome layers work in much the same way that layers in other biomes do. If you are still considered by the game to be in the underground layer then you're probably not going to notice a change in background.

Please note that biome suppression does happen; if there are too many snow and/or ice blocks near your mushroom farm then your mushroom biome may still be suppressed by the surrounding snow biome. Make sure that no snow, ice or slush is touching - or even close to - the mud where you have your mushroom grass growing.

And for safe measure, if you actually want to see a biome change, make sure your mushroom biome is definately in the cavern layer rather than the underground layer.

Hope this helps.

Yes you can. I play on a server with some friends, we built a base in the Snow biome, right below the surface. About... 70 blocks down from the entrance, we have a visible Glowing Mushroom farm, and even before it is visible, the Biome change effects(background is dark like night even in the day, music change) can be noticed easily.

For it to be a Mushroom Biome for the NPC, you'll likely just have to crank up the size of it. That is the simplest solution to any issues of the NPC not wanting to live in it. Maybe try about 150 to 200 tiles covered in the blue Mushroom Grass.

No you don't. I made this same mistake; mushroom trees can indeed grow on the surface.

.....

To clarify what I said earlier, if your farm is at 0 ft or higher then you will notica a background change outside once your farm reaches a certain size. If you have the farm in the underground layer then you won't see the background change there. You'll need to go outside to see it. The cavern layer is different because you will see a background change if you have the farm in that layer.

Thanks for the help, but I guess I should be more specific. I already do have a surface Mushroom Biome for the NPC with exactly one hundred blocks. This would be for catching Truffle Worms. I am getting Mushrooms. I believe the depth is around one hundred feet below 0. I checked the wiki pages for the Mushroom Biome and and Truffle Worm, and it said nothing about a particular depth requirement for it to spawn other than being below 0. So I guess the first thing I will look into is biome suppression. Right now any other blocks are at least three away from the mud blocks, so I'll try widening the gap. If worse comes to worst, I'll just enter into Hardmode and see if I can find a Truffle Worm. If not, I will definitely move it into the cavern layer as it is pretty close to the surface.

I guess the big question is where Truffle Worms can spawn. Does a farm definitely need to be in the Cavern Layer?

Well, after bit more digging, it seems that you indeed have to be in the Cavern layer for them to spawn. Damn, there goes all that work and Mushroom Grass Seeds. Oh well. Thanks again, guys. If I end up having any problems I'll probably report back.

According to the Wiki, truffle worms are Hardmode critters, though I haven't specifcally looked for any.

[Lushros Dofine]

They are indeed. I'm just preparing my world for Hardmode.

Well, to give an update on my progress, I've finished constructing my new artificial biome in the Cavern layer close to the bottom of the Snow Biome. It is over five hundred blocks of solid mud with mushroom grass in a straight line. There is a wood ceiling four blocks above the wood and a wood floor below the mud. Any Snow Biome blocks are four away from either ceiling. And yet, I still haven't been getting either the background or the music. At this point I'm not sure what I'm doing wrong as the Demize Key Mold farm, Jungle and suface Mushroom Biomes have all worked. In addition, the Underground Mushroom Biome I constructed in an older world works too. So I'm not sure if they just can't exist in Snow Biomes or I need to remove more biome blocks from the proximity of the farm. Does anyone have any advice?

I uploaded a picture of the farm to my screenshots, if that will better help you guys to figure out what's going on.

Try making the Mushroom farm taller, not just wider. For example, 5 rows of 100 mushroom grass, with 3 blocks up/down(player height) between each row, is more Mushroom-y then 1 row of 500 mushroom grass.

The game can only notice Biome related blocks within a certain distance of other blocks, so a single row, regardless of length, isn't nearly as effective as several rows.

[Lushros Dofine]

Is it because of the surrounding Snow Biome that the single row is ineffective? Because my Jungle/Mushroom Biomes on the surface are all on a single row with as few blocks possible to make the game recognize them (80/100, I think) and both work for me.

I have noticed enemies that don't spawn in the Snow Biome have been turning up in the farm. I added a second row of 500 below the first and now I'm seeing Cave Bats, Black Slimes and Mother Slimes. I'm assuming that the biome is taking effect even without music or background changes.

EDIT: This will probably be my last update on this topic, but success! After creating that second row and letting a good number of mushrooms grow in, the biome successfully changed over to Mushroom music and background. I had no idea that mushrooms would be a deciding factor, but the biome came in in areas with large amounts and did not where there were few. I added a third layer (which is definitely overkill), but at this point I'd rather take the extra time and resources to finish it instead of scrapping it and thinking of it as wasted time. I have a feeling that a single row would have worked had I let enough mushrooms grow in, but I do not want to take the other rows down and find out. Anyways, I took an updated screenshot if anyone needs any help with these, but I guess the design speaks for itself.

The mushrooms definitely count towards whether you get the biome music or not.

In the above screenshot, with the mushrooms I get the biome music, but the nearby snow biome appears to override the background.

The moment I harvest the mushrooms with the dart traps, the music goes away.

[Zemecon]

Just a thought: Maybe some biomes suppress mushroom biomes while others don't. The snow biome is relatively new so maybe the developers haven't programmed a way for it to be replaced yet...?

[JellyPuff]

i've noticed, that the snow biome music and background always overrides other biomes. (or the night music)

my hallow pierced right through my snow biome, and when i'm at the underground snow-hallow, i see crystals and hallow mobs, get souls of light and all that stuff, but the underground snow biome music still plays.

on the surface snow-hallow, all, that changes is, that a fade rainbow appears in the background, when i'm entering the hallow parts of my snow biome.

[Lushros Dofine]

I think that snow biome has extremely powerful suppression but that kind of makes sense to me. I think one possibility is the presence of snow and ice blocks specifically. Take the Corruption/Crimson/Hallow, for instance. Mud/dirt/stone/sand are all able to be converted, and they also make up the majority of their respective biomes. However, in the snow biome, only ice is converted, while snow remains completely untouched. So I think that the overwhelming presence of snow and ice together (especially since snow biomes seem to have less and smaller tunnels with more masses of blocks) means that it is highly suppressant to other biomes. I've also noticed that when you are on the border between the underground jungle and any other undeground layer the background/music changes when the majority of the blocks change. However, if you go to the same border but with underground snow, the background/music sticks around much further into the non-snow undergound. It makes sense logically, too. How easy could it be for a jungle/mushrooms to grow in the freezing cold environment? I'm assuming it was an intentional design choice to make it hard for other biomes to overwrite snow, as I was eventually successful in getting the changes to enemies, background and music.

[Zemecon]

What doesn't make sense to me is the complete lack of dirt or any other non-water-based substrate in the ice biome. It would be understandable for the surface to be composed of snow and ice, but the underground part? Is the snow biome some sort of huge frozen lake? I would expect at least SOME dirt and rock in the underground parts.

In any case, all that snow and ice is one big reason why you probably won't have a lot of luck starting a glowing mushroom farm there. It's the reason why the jungle is so efficient at blocking Corruption and Crimson areas from spreading, and why it is often quite difficult to start a regular grass-based biome/farm in the midst of a jungle.

[Lushros Dofine]

It can be done, though. Two rows of five hundred blocks with a moderate amount of mushrooms does the trick. One row might have been enough with almost all the mushrooms grown in, but I'm not going to be testing that one.
