Error during render

[slitterell]

It will render other maps fine. The custom nether maps it gives and error. I don't understand the error. It seems to stop repeatedly at tile 3800 on the netherroof map only.

[dynmap] Exception during render job: world=world_nether, map=org.dynmap.hdmap.HDMap@61a7f30b
Minecraft 1.15.2

All other maps work fine.

I think I have everything there you may need. I bet it is something simple I am missing.

Did you try to look at the chunk with mcedit? Maybe you can give the devs some data from there.

[slitterell]

It's 1.15 and I don't believe mcedit works with it unless you know how to and wish to disclose. :) I would happily, though, if it worked.

[slitterell]

Also, I verified disc space just to make sure. I even moved the whole server over to a new server to make sure.

@otse I also wondered how you could tell which chunk* it is?

[slitterell]

sorry, fixed the sentence to makes sense @otse lol my fault :)

Actually, just looked and got more errors when I just tried to run it again...

We seem to be having a similar issue with Dynmap-3.0-RC1-spigot.

I have added a flat and a surface map to the default nether map section. These two new maps render from Y-level 128 to 256 so we can see on top of the Bedrock ceiling.

Worlds configuration:

    -   class: org.dynmap.hdmap.HDMap
        name: flat_top
        title: Flat_Top
        icon: images/block_flat.png
        prefix: flat_top
        perspective: nether_top_map_scale16
        shader: stdtexture
        lighting: nethershadows
        background: '#300806'
        mapzoomin: 5
    -   class: org.dynmap.hdmap.HDMap
        name: nether_top
        title: Surface_Top
        icon: images/block_nether.png
        prefix: nether_top
        perspective: nether_iso_SE_scale16
        shader: stdtexture
        lighting: nethershadows
        background: '#300806'
        mapzoomin: 3
        boostzoom: 2

Custom perspectives:

  - class: org.dynmap.hdmap.IsoHDPerspective
    name: nether_top_map_scale16
    maximumheight: 256
    minimumheight: 128
    inclination: 90
    scale: 16
    azimuth: 180
  - class: org.dynmap.hdmap.IsoHDPerspective
    name: nether_iso_SE_scale16
    maximumheight: 256
    minimumheight: 128
    azimuth: 135
    inclination: 30
    scale: 16

It looks like changing maximumheigh to 255 instead of 256 solved our issue. I have no idea why I put 256 there since Y-levels only go from 0-255 in unmodded Minecraft. Definitely user error. But perhaps a check on max Y-level instead of a crash might be something to add?

[slitterell]

Interesting. Same with mine. It's still processing but it continued past its previous limit.

Easy to do as the build limit is 256, you'd think 256 is the limit. I did the same with mine. Seems like an error in programming but I'm am not a programmer.

[slitterell]

dang, I can't believe that was the issue. It appears to have rendered fine.
