The Copper Lantern textures isn't animated, this is because the animation definition is missing from the flipbook_textures.json files, the textures files is also different when compared to the Java counterpart, as the green part of the Copper Lantern isn’t animated and always has the same brightness.
Steps to reproduce:
Put Lantern and Copper Lantern (any variant) next to each other
Notice that the Lantern are animated, while the Copper Lantern isn't
Expected results:
Copper Lantern textures are animated, just like Lantern.
Observed results:
Copper Lantern textures isn't animated
This can be fixed by adding these to flipbook_textures.json files:
{
"flipbook_texture": "textures/blocks/copper_lantern",
"atlas_tile": "copper_lantern",
"ticks_per_frame": 8
},
{
"flipbook_texture": "textures/blocks/exposed_copper_lantern",
"atlas_tile": "exposed_copper_lantern",
"ticks_per_frame": 8
},
{
"flipbook_texture": "textures/blocks/weathered_copper_lantern",
"atlas_tile": "weathered_copper_lantern",
"ticks_per_frame": 8
},
{
"flipbook_texture": "textures/blocks/oxidized_copper_lantern",
"atlas_tile": "oxidized_copper_lantern",
"ticks_per_frame": 8
}
And replace the Copper Lantern textures with the Java one, otherwise it wouldn't have any effect as the animation itself is missing from the textures.
All the relevant fix is available in the attached .mcpack files.
the same can be said for the soul lantern
