someone knows good editor 3D to Worms 4?
I want to modify map

We all want to modify maps. :(

There isn't one AFAIK. At least a legal one.

If you want a map editor, then search to Dream17 forum. I do not have a link, but search in Google.

there is an editor that sort of works, but it isn't very good. there is another person working on a better version now, and it should be out soon.

can you tell us the version that is out now?

Go search on the Dream17 forums for it. I've tried using it, but I find it nearly impossible.

I downloaded the WMap Editor from Dream17 and it didn't even work. The only thing I saw was a black screen and nothing.

me to. but I think I did somthing wrong.

Where The Hell is that map editor?

It's a black screen because you didn't read the readme on how to load a map, did you? First, you drag the .xan file onto the program icon. Then it appears in the window, and you can edit it with the keys listed in keys.txt.
Also, have a look at that "Map Editor for Worms3D" thread by AlexBond. It works on Worms 4 maps too!
