GTToolMapper
Automatically maps GregTech machine recipes (Assembler, Chemical Reactor, etc.) and fluids to ProjectE EMC values

GTToolMapper: GregTech & ProjectE Integration
GTToolMapper is a specialized compatibility addon that bridges the gap between GregTech CEu Modern and ProjectE.
By default, ProjectE cannot "see" recipes inside complex GregTech machines (like the Assembler, Chemical Reactor, or Fluid Extractor). This means complex components like Electric Motors, Circuits, and Cables often have no EMC value, breaking the progression in high-power modpacks like Monifactory.
This mod acts as a custom EMC Mapper, scanning GregTech's internal recipe registries and teaching ProjectE how to calculate costs for machine-only items.
Key Features
- Machine Recipe Scanning: Automatically maps recipes from the Assembler, Chemical Reactor, Fluid Extractor, Wiremill, and more.
- Fluid EMC Support: Successfully calculates EMC for GregTech fluids (e.g., Molten Iron, Rubber, Soldering Alloy) by tracing them back to their solid ingot/dust forms.
How It Works
-
Install the Mod: Drop the
.jarinto yourmodsfolder alongside GregTech CEu Modern and ProjectE. -
Launch the Game: The mapper runs automatically during the server startup/recipe registration phase.
-
Check Your EMC: Items that were previously un-mappable (like Cables, Rotors, and huge pipes) should now have valid EMC values derived from their raw materials.
