Hello, I came here asking for help regarding the PC Steam game Sky: Children of the Light. I've been trying to get the model files to open inside of Noesis, but every file appears to be a .mesh file. Natively, this format couldn't be opened in Noesis, so, about a year ago, I've commissioned a kind person to make a plug-in that supports .mesh files ("fmt_mesh.py" in attachments).

Issue is, the script throws an error every time I try to preview a model (sample files as examples).

The creator no longer wants to work on the script, and I have gotten permission to share and edit it. If anyone has any knowledge of this, please give it a shot, I hope the plug-in is a good foundation for the models.

fmt_mesh.py samples.zip

because the structure is different

Previously you used the android version

code to unpack the model:

Spoiler

import os
import struct
import lz4.block
import sys

if len(sys.argv) > 1:
    file_path = sys.argv[1]

    with open(file_path, 'rb') as f:
        # read uncompressed size
        f.seek(86)
        uncompressed_size = struct.unpack('i', f.read(4))[0]

        # read compressed size
        f.seek(82)
        compressed_size = struct.unpack('i', f.read(4))[0]

        # get compressed content
        f.seek(90)
        compressed_data = f.read(compressed_size)
        # Unpacking data
        uncompressed_data = lz4.block.decompress(compressed_data, uncompressed_size)

        with open(file_path.replace('.mesh','_U.mesh'), 'wb') as wb:
            wb.write(uncompressed_data)

os.system('pause')

 

but after the model there is still a skeleton and after the skeleton there is still a lot of data. I haven't checked what it is

Oh thank you for clarifying, I've tried to research about the other stuff but came up with nothing. And I can't find anyone who is willing to try if I commission them, so I'm trying my luck here.
