• Rebalanced batch sizes, utility requirements, and production rates across large portions of the chemistry system.

Bulk Production

• Increased practical throughput for construction and commodity materials.
• Reworked batch sizes for concrete, asphalt, soil, water treatment, acids, fertilizers, polymers, gases, and other high-demand materials.
• Reduced excessive grind while retaining industrial-scale resource and energy requirements.

Machines & Progression

• Audited machine recipes, costs, capabilities, and progression placement.
• Rebalanced machines whose performance did not match their construction cost or intended role.
• Added, replaced, renamed, or deprecated machines where needed to improve progression.
• Improved early-game power and industrial progression.

Fluids & Infrastructure

• Improved fluid quantities, tank capacities, piping, and machine integration.
• Added shared multi-fluid piping support.
• Standardized fluid handling across more machines and processes.

UI, NEI & Information

• Improved machine GUIs, tooltips, fluid displays, and electrical/thermal ratings.
• Expanded NEI information for industrial processes.
• Fixed numerous missing, incorrect, or broken recipe displays.

Fixes & Consistency

• Large audit of recipes, material conversions, machine behavior, fuel handling, and process accounting.
• Fixed numerous progression blockers, invalid recipes, incorrect quantities, and inconsistent machine rules.
• Improved overall consistency between energy, chemistry, metallurgy, fuels, and industrial production.

RTM 3.X is effectively a full Real-Sim overhaul of HBM's industrial systems, starting with oil processing and extending through performance, energy, heat, chemistry, metallurgy, machines, infrastructure, and progression.
