Spray Coater's purpose is to apply Proliferator sprays to the items passing through. Proliferated items receive various bonuses depending on how they are used. The Proliferators enter the spray storage of the Spray Coater through the top belt passage, while the item to be sprayed pass through the bottom belt passage.
The Spray Coater's storage holds sprays instead of Proliferators, which get converted to sprays when entering. The storage capacity is 600 sprays and it can overflow if the free space is less than the number of sprays in the entering Proliferator. If the storage is full or holds different Proliferator tier, the Proliferator item will pass through the Coater.
If the stacked cargo passes through the Spray Coater, the whole stack is applied Proliferator points, spending the amount of sprays corresponding to the number of items stacked.
Spray Coaters can be installed on a belt that is installed in the air without requiring to have ground beneath itself, or stacked one onto another before passing belts through them. The baseline stacking limit is 7, increased by 3 per each level of the Vertical Construction upgrade, up to the maximum of 25. If the maximum stacking level is reached, one will only be able to feed the Coater at the top by hand, as no belt will be able to reach the Coater's Proliferator input.
Items with Proliferator marks receive various bonuses depending on the type of activity they are involved in. The amount of the bonus depends either on the Proliferator's Production Speedup or Extra Products parameter. Some of the activities also apply the item's Energy Consumption penalty to the building that processes the item.
|Production||Any production building (except the Fractionator) can get either Production Speedup or Extra Products bonus if all the recipe ingredients have the same-tier Proliferator mark, depending on the building settings, chosen by the player (the default is Extra Products). If one of the ingredients has lower-tier mark or no mark, the lowest or no bonus will be applied.
The exception is the production of Antimatter, Antimatter Fuel Rod and buildings that take other buildings as the ingredients (such as Mk.II and Mk.III Belts, Sorters or Assembling Machines. Production of these can only benefit from the Production Speedup bonus of the Proliferator.
The Production Speedup bonus is multiplicative with the building's Crafting Speed. For example, applying Proliferator Mk.III to an Assembling Machine Mk.III will result in Crafting Speed of 3 (+100% out of the building's 1.5).
|Research||When used in Research, proliferated Matrices produce bonus hashes according to the Proliferator's Extra Products bonus.||Yes|
|Fractionation||Proliferated Hydrogen will increase the Fractionator's conversion rate by the Proliferator's Production Speedup bonus. For example, a Proliferator Mk.III will yield a 2% conversion rate (+100%).
Note that passing through Fractionator does not remove the Proliferator marks from the Hydrogen unless it gets converted.
|Proliferators||Spraying the Proliferator itself gives more sprays in the Spray Coater, increased by the amount of Extra Products bonus. It's always worth it.||No|
|Proliferated Graviton Lenses increase Ray Receiver's maximum power collection rate by the Proliferator's Production Speedup bonus. This applies to both Power Generation and Photon Generation modes.
The Proliferator bonus is multiplicative with the innate bonus of the Lens, therefore using a Lens sprayed with the Proliferator Mk.III would result in 400% of the baseline generation (200% with Lens × 2)
|Proliferated Fuels (except Antimatter Fuel Rods and Full Accumulators) increase both the Fuel's energy capacity and the Power Generator's power output by the Proliferator's Extra Products bonus.
When burnt in the Mecha's Fuel Chamber, the Extra Products bonus applies to the Fuel Chamber Generation rate. The bonus is multiplicative with the Fuel's native Fuel Chamber Generation bonus, thus resulting in, for example, 187.5% Generation for Energetic Graphite with Proliferator Mk.III mark (150% × 1.25).
|Proliferated fuels Antimatter Fuel Rods only increase the Artificial Star's power output, but by the amount of the Proliferator's Production Speedup bonus. It does not alter the Rod's fuel capacity, thus resulting in faster burn rate.
When burnt in the Mecha's Fuel Chamber, the bonus applies to the Fuel Chamber Generation rate instead. It is multiplicative to the innate bonus, thus resulting in 1200% Fuel Chamber Generation.
|Full Accumulator||Similar to Antimatter Fuel Rods, Full Accumulators get their Fuel Chamber Generation rate affected by the Proliferator's Production Speedup bonus, but only in the Mecha's Fuel Chamber.
Other Accumulator's abilities to store and transfer power are unaffected by the Proliferator bonuses in any way.
