EDIT: I fixed the issue already. You can just ignore this.
I’m using jMc2Obj to import a Minecraft world into Blender. The model imports perfectly, and every object is assigned a color, but there is a problem: although the textures and UV maps seem to be imported, none of the textures show up! Instead, they all show as magenta in the viewport when I enable textured rendering mode. I can see that the .png files were imported in the hierarchy, and the object has a UV map.
If you’re also having this issue, the issue was that if you export textures as a single file, the change won’t propagate automatically, so you must enable the single texture file setting in the model settings.
