If so, don't forget to change two places. One is that the v3 warhead should be replaced with your new one, and the other is that don't forget to register in the warhead list.
If you modify the original v3 warhead, the registration list does not need to be changed. If you make your own warhead, you have to add your own warhead.
For example, if you make a warhead and name it [V3dt], then you use Notepad to search for [warhead] (including brackets), and then you will find a list of 1= what 2= what ... This is the warhead list. After the last number, for example, 100=xxx, you add another line.
If you do it yourself, change the default warhead of v3 to yours. Search v3 warhead = you will find this paragraph:
V3 warhead =V3WH
DMislWarhead = DMISLWH
V3EWH warhead =V3EWH
DMislEliteWarhead = DMISLEWH
CMISLWH warhead =CMISLWH
CMislEliteWarhead = CMISLEWH
Among them, DMisl stands for fearless missile, CMisl stands for thunder missile, and Elite stands for elite, that is, the change of warhead after level 3.
Replace the corresponding one after the equal sign with your new warhead.
The radiation range is the same as the explosion range of the warhead, and it seems that it cannot be changed.
The maximum explosion range of a warhead is 10 (like a nuclear bomb), and any higher explosion will cause a window jump. However, it is also possible to release multiple submunitions with the first explosion of submunitions, and each warhead is a nuclear explosion.
I have not tested the setting of submunitions, so I won't talk about it for the time being.
