We'd like to request either a config to toggle the forestry integration for the fermenter, a config to set the biomass output of BoP saplings in fermenter or a general reduction of their output. As it currently is the worldgen BoP trees produce 5x the amount of vanilla tress and nearly as much as the best forestry tree that takes extensive breeding to obtain. For our pack this is quite unbalancing for energy production.

I just looked at this now, the values are in line with the defaults of Forestry. I'm really not too keen on config options for it as i mentioned before.

I'm sorry but they are not in line. Vanilla trees give 0.05 units/sapling. IC2 Rubber trees give 0.05 units/sapling. MFR rubber trees don't work. Forestry trees. the highest level that is achieved, only with 5th generation trees, is 0.3 units/sapling. That is a substantial amount of time, effort and resources to achieve this production. Your trees and Extrabiome XL trees, which are worldgen and require no effort output 0.25 units/sapling. So you get 85% of the max production with no investment. That is not what I consider in line. If you do not wish to fix this discrepancy that is fine. It is your mod you are clearly free to do whatever you want with it. However don't pretend it is balanced.

No. This just tells me you are not using those settings which are default to Forestry.

As per https://github.com/Glitchfiend/BiomesOPlenty/blob/BOP-1.7.2-2.0.x/src/main/java/biomesoplenty/common/integration/ForestryIntegration.java#L38
We use the value 250.

As per https://github.com/ForestryMC/ForestryMC/blob/cfa8d5302557a512ac2d4e22ae647e232836b27c/forestry_common/core/forestry/core/GameMode.java#L112
and
https://github.com/ForestryMC/ForestryMC/blob/cfa8d5302557a512ac2d4e22ae647e232836b27c/forestry_common/core/forestry/core/GameMode.java#L68

The default value is also 250. If you want to play games with me that's fine and all but there's evidence right there that doesn't go in your favour. We've bent backwards far enough to support Forestry, and we will not be going any further to support its config options.

We design BOP around defaults, as does Sengir for Forestry. When you change those defaults, you're changing the design of the mod from what it was intended. That's fine, and i'm not going to say you can't do that, but it's up to you to pick up the pieces as a result of your changes.

Also, 'don't pretend it is balanced' reeks of someone who has failed to do their research and is merely spouting out because something isn't the way they want it to be. This makes me never want to include any such config options in BOP as it attracts users such as yourself.

I apologize for my short tone, it was not productive. I will endeavor to find an alternative means of balancing the output for our pack.
I'm not a programmer so I don't have the ability to fully grasp the code. However I see that the way forestry deals with values in the the various difficulty settings is different then I understood them to be. I was under the belief that the scaling of output was determined at a different point and would affect all inputs to the fermenter. My numbers were based on in game values on our server which does run forestry on it's hard setting.

Sorry for wasting you time.

I'm happy to balance the existing integration to work better with Forestry, however config options for integration is pushing it a bit too far for me.

Thank you. The config was a compromise if you wanted the high biomass value. I was hoping just for the offered rebalance. Thank you.
