Sector Numbers

[Homer_hardware]

I am/Im currently building a doom map on Ultimate Doom Builder and I am trying to change a sector's brightness but it also changes the brightness of another sector and apparently they both have the same sector numbers. Do you guys know how to change the sector number?????

It's the sector tag.

When you right-click a sector, at the bottom of the window that opens up, you'll find the Identification tab, there you can give your sector any tag you want (must be an integer)

Sounds to me like you might have accidentally merged the two sectors. when you merge 2 or more sectors together, their properties will be the same and they'll have the same Sector #. This can be helpful if you want two sectors to be the same but disconnected from each other (look into like dummy sectors and stuff for more info). I don't use ultimate doom builder, but some editors have hot keys for you to disconnect sectors that were previously merged; though I'm not sure how you'd go about it using doom builder.

 

Sector tags are unrelated. They are very important though when mapping. Say if you want to have a switch that lowers a floor, you would give the switch and the floor the same tag so the switch would know which sector to lower.

 

My bad if I'm misunderstanding, but thats just my 2 cents...

Thats probably what it is tbh since even if I give one of them a new sector tag they will still both be selected. Thanks for helping.

There's a fix for this, there's a button in UDB called "Make Sector," which allows you to separate sectors which have been joined together. I think using that will fix your issue.
