Forest Converter v1.0

Forest Converter v1.0

Forest Converter is a universal tree-conversion script mod for Farming Simulator 25 on PC and Mac. It replaces safely isolated standing map trees with a configurable mix of verified mature forestry trees.

Unlike a small radius-based replacement tool, Forest Converter can scan:
The entire map
All farmlands owned by the current farm
Only the farmland where the player is currently standing

Every conversion starts with a protected preview. You can review the number of eligible trees, skipped-tree safety information, and normalized species mix before confirming any changes.

The default mix is:
50% Silverrun Pine
50% Silverrun Ponderosa Pine

Lodgepole Pine, Giant Sequoia, the bundled Pine and Spruce mature variants trees, and other compatible species remain optional at 0% until you choose to include them.
Important: Back up an existing savegame before converting trees. Conversion changes the savegame-managed tree population and is not intended to be an undo tool.

Main features
Dedicated Settings > Forest Converter tab
Works on fresh starts and existing savegames
All Map Trees, Owned Farmlands, and Current Farmland scopes
Configurable weighted tree-species mix
Weights are normalized automatically; they do not need to total 100
Protected preview and confirmation before conversion
Trees are processed gradually to reduce frame spikes
Mature replacement models are created immediately
Compatible map and enabled tree-pack registrations are detected automatically
Only verified mature forestry targets are offered by the converter
Cut trees, logs, stumps, protected objects, and unsafe tree hierarchies are skipped
Automatic circuit breaker disables conversion safely when an unsupported condition or excessive failure rate is detected
Thirteen bundled mature forestry trees are also individually placeable from the Construction menu
Optional Forest Converter Sapling Add-On with eight pallet sizes and dynamic species selection

Bundled Forest Converter trees
The following 13 credited mature tree models are registered under unique Forest Converter species names:
Spruce Variant 1
Spruce Variant 2
Spruce
Scottish Spruce Variant 1
Scottish Spruce Variant 2
Scottish Spruce Variant 3 — repaired distant LOD
Pine Variant 1
Pine Variant 2
Old Pine
Scotch Pine
Riverside Birch
Cypress
Eucalyptus

They are available as optional conversion targets and under:
Construction > Landscaping > Forest Converter Trees
Construction placement creates a mature, registered tree without converting or changing any nearby trees.
Optional Sapling Add-On

FS25_ForestConverterSaplingAddon.zip is an optional companion download.
It adds liftable pallets containing:
6 saplings
24 saplings
40 saplings
60 saplings
120 saplings
175 saplings
240 saplings
300 saplings

The Tree Type selector is built from FS25’s active plantable-tree registry, allowing all 13 Forest Converter registrations—and other compatible active species—to appear without relying on a fixed hard-coded list.

The pallet displays the selected supported species name, and the label color can be changed in the shop. Forest Converter saplings use a compatible young stage and grow into the selected mature model.

Giant Sequoia remains an explicit oversized option. It should be treated as a chainsaw tree because its mature trunk is generally too large for a normal wood harvester.

The Sapling Add-On has its own technical mod identity and does not replace the original Tree Sapling Pack. Both can remain installed, although this will add similar pallet products to the shop.
Requirements
Forest Converter

Farming Simulator 25 for PC or Mac
FS25_ForestConverter.zip
FS25_SilverrunTrees.zip by Jos — required separately and not included

Optional Sapling Add-On

Installation
Delete older copies of Forest Converter and the Forest Converter Sapling Add-On from your mods folder. Do not keep renamed duplicates.
Place FS25_ForestConverter.zip in: Documents/My Games/FarmingSimulator2025/mods
Place FS25_SilverrunTrees.zip in the same folder.
If wanted, place FS25_ForestConverterSaplingAddon.zip in the same folder.
Do not unzip the mod files.
Enable Forest Converter and Silverrun Trees when loading the save.
Enable the Sapling Add-On as well if you installed it.
Fully restart the game after replacing an older version.

Using Forest Converter on an existing savegame

Back up the savegame.
Load the save with Forest Converter and Silverrun Trees enabled.
Open Settings > Forest Converter.
Check the Universal Compatibility Status.
Select a conversion scope.
Set the desired species weights.
Select Preview & Apply.
Review the eligible-tree count, skipped-tree summary, and normalized mix.
Confirm the conversion.
Wait for processing to finish before saving the game.

I recommend testing Current Farmland first. This affects eligible trees across the entire parcel where the player is standing—not merely the trees immediately around the player.
Using Forest Converter on a fresh save

Forest Converter can offer a protected preview after the new save finishes loading. You may confirm the current settings or decline, open Settings > Forest Converter, adjust the scope and species mix, and then select Preview & Apply.

No trees are changed until a preview succeeds and you confirm it.
Why some trees may not change

Forest Converter intentionally does not force every visible tree through conversion.

A tree may be skipped when it is:
Already cut, split, or lying on the ground
A stump or loose log
Player-planted or managed by the savegame tree system
Attached to a vehicle, placeable, mission object, or protected scene object
A deliberately excluded mission tree
Decorative geometry that is not registered as a usable tree by the map
Part of a tree hierarchy that cannot be isolated safely
Located outside the chosen farmland scope

Skipping these trees is a safety feature, not necessarily an error. Some maps construct forests in unusual ways, so universal compatibility cannot be guaranteed for every decorative tree on every map.
Conversion safety

Forest Converter fails closed when it cannot verify that conversion is safe. Its circuit breaker can disable conversion for the current session if required managers are unavailable, tree hierarchies cannot be isolated, an unexpected exception occurs, restoration fails, or replacement failures exceed safe limits.

If the circuit breaker activates after conversion has started, do not save the game. Exit and reload the backed-up save, then retain the complete log.txt for diagnosis.
Species weights

Weights are relative and normalized automatically.
Examples:
50 Pine / 50 Ponderosa = 50% / 50%
25 Pine / 25 Ponderosa / 50 Lodgepole = 25% / 25% / 50%
30 Spruce / 30 Pine / 40 Ponderosa = 30% / 30% / 40%

A species set to 0% will not be selected during conversion.
Advanced console fallback

The settings interface is the recommended method, but the following console commands are available for testing and troubleshooting:

fcmPreview [map|owned|current] fcmConvert <map|owned|current> CONFIRM fcmCancel fcmMix fcmSetWeight <treeTypeName> <0-100> fcmResetMix

Compatibility and limitations
PC and Mac only
Single-player only
Requires Silverrun Trees
Designed for both new and existing savegames
Map compatibility depends on how each map registers and structures its trees
Player-planted trees and trees produced by an earlier conversion are protected from later map-tree scans
Decorative and unsupported tree geometry may remain unchanged
Giant Sequoia is oversized and is not intended for a normal wood harvester
Always test on a backed-up save before converting a large area or the entire map
