Yes but in normal gameplay this should never happen. Also it depends at what age they generated at. 95 is the max age that they can generate at with this mod installed. so you would have to wait around 5 years for them to change texture.

A mech being alive for an extra 5 years should almost never happen unless you really like keeping enemy mechs as pets. This also apply's to mechs you build yourself but you have to wait 100 years and no sane person would have a mech alive for that long nor a save game that lasts 100 years.

hope this answers your question

Do the mechs turn green if you have the patience to wait 100 years (in rimworld time)?

@Vivus Blydyr
I am aware of this point but there are cases in a few mods that the mod only replaces the clean textures of the mechs but not the ancient textures which at that point makes everything look stupid.

The goal of this mod is to give players the option to decide if they want Mechanoids to have constant textures or not. And also this mod does not override the colour markings that base game player owned mechs have.

Also just setting “show mech names” to always helps as well

Enemy mechs looking like this makes makes sense considering they are usually ~1000 years old in their bio tab, the outer plating has oxydised and thus the tint. Also serves a gameplay purpose to help tell apart enemies from friendly\neutral entities at a glance.

@StockSounds

Because I want my mechs and NPC mechs to look the same base texture wise since I often use retexture mods

Out of curiosity, how is it possible to dislike the greenies?
