# Factory Plant EffectÂ¶

The cost reduction effect of `FactoryPlant`

buildings like the Industrial
Plant can be modified per TechnoType, using this multiplier.

`[TechnoType]â–ºFactoryPlant.Multiplier=`

(double - multiplier)The effect of the respective

`CostBonus`

tag for this type is multiplied by this value to either increase, decrease, or nullify the effect. Fully supported values range from -1.0 to reverse the effect to 1.0 to not apply the effect. 0.0 nullifies the bonus. Defaults to 1.0.Note

Values beyond 1.0 can potentially cause the cost to drop to zero, if the effect of the product of all cost bonuses is multiplied by a too large value. This is because the effect of this multiplier is linear.

An example: If the cost bonus is 0.6 and the multiplier is 0.5, then the final bonus will be 0.8. In other words: if a bonus reduces the cost to 60% and the multiplier only grants half of that, the final price will be at 80% of the original cost.
