环境特效是要专门设置的

星云效果也是要添加一种修正，不一定要是隐形

effect solar_system = {
create_nebula = {
name = 太阳星云 “星云名称”
radius = 30 "星云大小"
effect = {
add_modifier = { modifier = nebula_cloaking } “星云修正，这里是隐形强度+3”
create_ambient_object = {
type = "rare_nebula_1"
location = this
}
last_created_ambient_object = {
set_location = {
target = prev
distance = 0
angle = random
}
}
}
}
}
