Did you use the /bluemap render command?
Also, the path to your world seems odd:

# The path to the save-folder of the world to render
world: "world/world2"

if your world world2 is directly in your server-folder try to use:

# The path to the save-folder of the world to render
world: "world2"

[skyboooox]

• Of course, I executed it after the initial configuration.

 bluemap render world2
But he is still like this

• I just followed your suggestion and changed it to

# The path to the save-folder of the world to render
world: "world2

But something went wrong

Hmm, So your world is in the folder ...\3sever - 10\world\world2? Then world/world2 was correct..
Are there any files in ...\3sever - 10\bluemap\web\data\world2 ? There should be two folders lowres and hires with more folders and files in them.

[skyboooox]

NO

[skyboooox]

This is the directory structure of the ./world

[skyboooox]

I reloaded again, .\bluemap\web\data Still no change

huh .. why is the render task disappearing ?
this is weired,..

Do you use a resourcepack?
Is it possible to send me the world2 so i can try to reproduce this?

[skyboooox]

-I did not add resourcepack
-I just modified it and reloaded it. Now it can display the world, but it still ca n’t display the world2. If my webpage can be accessed normally, you can check

[TBlueF]

I can see your webpage.
I will test the world2 in a couple minutes..

[TBlueF]

Ahh, i already found the problem:
All chunks are marked as not yet light-populated that means that the light-calculation has not been done yet by minecraft on all chunks.
BlueMap is skipping those chunks because it needs the light-data.
I don't know why there is no light-data yet, is that a mod world/dimension?

[skyboooox]

This is another world create with the Sponge plugin Nucleus

[TBlueF]

Hm, i fear i cant help you further here. This is not a bug with BlueMap but an issue with something else. Maybe Sponge or Nucleus. The light data is essential for BlueMap to render the world, and as long as it is missing it wont render :/

[skyboooox]

Okay thank you
