[YukihiraDeve]

Hello,
When I using jMc2Obj-124.jar on my Debian server, with this command line

java -jar jMc2Obj-124.jar /servers/world/

I have this result.

the MTL files have size 0ko.

In the console, we have a lot of error. Lot of texture block missing and available.

I try to add minecraft.jar link, but a args not be unavaiblable

this is a log when I export my map :

Done! ```

I've checked the administrator and writing rights, and the version is indeed the right one.

If you have an idea thank you a lot :)

hi, I would like to know how you dealt with this, cause I met the same problem. Thanks!

Hi,
I used it this line with my terminal script.sh :

java -jar "$jmc2objPath" --resource-pack="$MinecraftJarPath" "$worldPath" --area="$minSpawnX,$minSpawnZ,$((spawnX+60)),$((spawnZ+60))" --offset=center --object-per-mat --height="$min,$maxY"

and for $MinecraftJarPath, I used this :
MINECRAFT_JAR="https://piston-data.mojang.com/v1/objects/05b6f1c6b46a29d6ea82b4e0d42190e42402030f/client.jar"

The problem is that the Jmc tool does not have the default textures. By default it uses .minecraft. Except that on a Linux server it is not necessarily available, so I downloaded a client.jar and it was good!
