Cubik Studio

After the obj file with texture is loaded and voxelized
export it to a schematic file and use a program called MC EDIT
I want to place it in MineCraft.

When you open a SCHEMATIC file in MC EDIT
The circuit diagram continues to be damaged.

Please tell me how to do it.
I can not even see both the forums and tutorials here.

It is a very urgent problem.
Please answer as soon as possible.

Error: KeyError('key data not found.',)

In addition, after importing a schematic file from Cubic
If you save and load it again, nothing will be output.
So it seems that mc edit says there is no data.
Let me know how to call obj and change it to a voxel and then to mc edit
