Thaumcraft 4.1g: Infusion stability questions...

[desht]

So after a little research, I've found quite a few conflicting answers about this, and I'm hoping maybe some of the TC4 experts here might be able to shed some light on some questions I have:

1. I understand the range at which the infusion altar picks up stability blocks is 12 in each horizontal direction, 5 below and 10 above the matrix block - right?
2. Do aura nodes count toward stability/instability? Since I've just moved a bunch of nodes to a floor just above my infusion altar, this could be important
3. When the altar considers symmetry, is it only horizontal symmetry (X/Z axes)? e.g. if I put a zombie head at x+5, y+5, z+5 relative to the matrix, should there also be a head at x-5, y+5, z-5? Or at y-5?

Thanks

Stabilizers dont need to be symetrical, dont now about the rest, dont think the nodes stabilize tho.

I don't believe it doesn't check for symmetry on the Y axis, but so far that looks mostly correct.
IIRC Nodes may be a stabilizer, but even if they aren't, they are(IIRC) a usable source of aspects for infusion, so place them accordingly(aka either balanced or away from the altar).
Also not totally sure how far it checks on either side of the Y axis, but I do know that a bunch of candles under the ground under the altar can stabilize pretty much anything(it's just a lot of candles is all).

 

[Democretes]

The range listed is correct. It works well to use this range to put an absurd amount of candles below the altar while putting jars and such above to make it aesthetically pleasing.
Nodes used to count towards instability, it doesn't seem like they do any more. Crystals, skulls and candles all count towards instability, but they are all worth the same value.
The altar will consider Y symmetry when checking for stuffs.

That doesn't make sense. If a layer of candles under the alter contributes to stability, then surely it isn't checking the Y? If it were, then you'd need a matching layer of candles above the altar. Or, you could have one half under the altar, and the other half above the altar, and then they'd balance each other.

Yeah, need symmetry on the x and z axis, not the y. Nitor and nodes used to count for stability, but no longer do in 4.1.

Burying a ton of candles underneath your altar is a good, and cheap, way to stabilize things without cluttering up your infusion room.

 

[vertagen]

Btw, how much blocks belo the actual floor, where you have your pedestals sitting on affects the infusion ?, 1 or 4 ?

Good information, thanks everyone! Having done a few infusions just now, it seems like the cluster of nodes near my altar aren't causing any noticeable problems, so I'm guessing nodes don't count now. It also makes sense that the Y axis isn't considered for symmetry.

Erm, the y-axis is the only axis considered for symmetry. I think you meant the y-coordinate, but it is considered for symmetry, too. I'ts just not important, if both items are above or below the altar as long as they share the same y-coordinate.

In mathematical terms: Both items have to be axis-symmetric to an axis parallel to the y-axis passing through the center stone of the altar.
In coordinates: Both gizmos have to be on the same y-coordinate and a line drawn between them has to go through the same x and z coordinates the center of the altar is on.

Of course. You're right, it's all about 180° rotational symmetry around the Y-axis.

Yes, that was my understanding - I just didn't express it very well

I missinterperated it as y-choord not y-axis. Whoops.
