The Void Resource Miner is a multiblock structure added by Environmental Tech. It can create various natural materials, such as Clay or Soul Sand using energy (FE). It comes in 6 tiers.


When supplied with enough Forge Energy, the Void Resource Miner will periodically generate natural materials of various types, which will be automatically output to inventories adjacent to the Controller. This process can be sped up by placing Speed Modifiers in the appropriate slots in the structure. Specific blocks can be made more likely to appear by using a colored Laser Lens, and this effect can be amplified by using Accuracy Modifiers.

The Void Resource Miner also requires its Laser Lens to have a straight view to either Bedrock or The Void in order to work. Transparent blocks such as Glass, walls, or fences may be used to provide a safe path under the structure without blocking the beam.

The stats of each tier of Void Resource Miner are given in the following table. "Minimum time per block" is the minimum time per block that this tier of Void Resource Miner can reach using Speed Modifiers, "Modifiers to reach max speed" is the amount of Speed Modifiers needed to reach it and "FE per block (max speed)" and "FE/t (max speed)" are the respective values when this amount of Speed Modifiers is used. Note that adding more Speed Modifiers than this value will increase the FE per block (and thus FE/t) without increasing the speed, thus wasting power.

Every time the Void Resource Miner produces a block, it is randomly pulled from a table depending on its tier. These tables can be freely configured, including their contents and the weight of each entry (entries with higher weight will be picked more often). By default, this includes a variety of naturally occuring blocks, such as Stone, Andesite, Mycelium, and is the only way to obtain Mica.

If the appropriate colored Laser Lens is used, the item will have a bonus to its weight, according to the following formula:


  • bonusWeight is the bonus weight given to each appropriate entry
  • totalWeight is the sum of the weight of all entries (before the bonus is applied)
  • nbEntries is the total number of entries
  • accuracy is the amount of Accuracy Modifiers in the structure
