I'm fiddling with a added scaletype, where I try to put tech restrictions on the heatshields, but I'm currently getting arrayoutofindex error. @PART[HeatShield1]:FINAL { @MODULE[TweakScale] { @type = stack_square_techRestricted } } SCALETYPE { name = stack_square_techRestricted freeScale = true defaultScale = 1.25 suffix = m scaleFactors = 1.25, 2.5 techRequired = surviveability, enhancedSurvivability // scaleFactors = 0.1, 0.3, 0.625, 1.25, 2.5, 3.75, 5.0, 7.5, 10, 20 // incrementSlide = 0.01, 0.025, 0.025, 0.025, 0.05, 0.05, 0.1, 0.1, 0.2 // techRequired = precisionEngineering, miniaturization, engineering101, surviveability, generalConstruction, enhancedSurvivability, advConstruction, advSurvivability, spesializedConstruction, advMetalworks TWEAKSCALEEXPONENTS { mass = 2 } } Is this the right way to go about it, cause I cant seem to find any other examples or tweaks for limiting tweakscale in career mode. Would be great to get rid of some extra parts by doing this as well ;P EDIT - seems I misspelled the first tech, should be "survivability" but if someone has a tip for career mode I'll listen, cause adding my own configs for every type seems like unnecessary much work
