1)No it's worth it using it but you can learn from it few things
2)what do you mean by seeing numbers of objects?
The limit 30k is only so the map doesn't lag or cause crashes.
1) I don't really understand what you said
2) A user below answered that ^^
Hit F11 to display the object manager, it will show the number of doodads and stuff on your map.
Thank you, I didn't know that!
JNGP was superseded by WEX, which you can download from this site. Both are mostly unnecessary if your WE is updated to 1.30+
If you want the most utility JNGP is the way to go. If you don't need all the utility that JNGP has then go for WEX.
However, these options require older version of the game.
Until the editor has been patched with everything we had, I would recommend keeping an older version of the game around.
It's not that I don't like WEX, but to me it doesn't feel like that much of an improvement. Also...
The thing I needed the most was an increased limit to the number of placed doodads, so...
I tested the limits of JNGP myself and it exceeds 30k doodads placed. I handplaced 35k doodads and the map was saved and tested properly.
The 1.30 version still supports only 30k, I tested it.
The reason I am asking is beacause I am working on a really ambitious project for which I do need over 30k doodads.
Now, as Chaosium pointed out, I can see that there's a separate limit for trees and other doodads, and also a 256 limit to the items number.
My new question is: is the limit of doodads separate from the limit of trees? I really don't want to place 30k doodads again to find out...
Also, the limit for items is for number of placed items in game or custom created items?
By the way, thanks a lot for the answers so far.
