Help request with a bugged *.dat

[VonDos]

Hi everyone!

This is an help request for hex \ code experts...

I was working on a 3d model when i import an obj via pack3d, but something gone wrong, and now i can't open the file no more.

This is the error he gave me:

https://i.ibb.co/8r3qZ4V/Nuova-immagine-bitmap.jpg

Is this file saveable, or i must rebuilt it from start?
(sadly, the backup copy is old, i reworked some 3d parts and a lot of nodes with guns, A\A, searchlights...)

Thanks for everyone interested, and best regards,
Vd

We'll have to start all over again.

Hello, VonDos.

"Chunk index: 18" --> Sequence number of the data block.
"Chunk offset: 0x001dc4e0" --> Start of data block (address).
"Parsing stopped at: 0x001dc4e8" --> Address of stopping block reading.

In other words, after reading eight bytes of the chunk, the reading was interrupted because the program detected an error... probably in the last four bytes where the data block size of this chunk is written.
The message goes on to say '...: Invalid chunk size (-274006004 bytes)', which also indicates an incorrect size (second 4 bytes).

Good luck.

Hi Anvart!
The problem was solved by reconstruction of the file, using an old backup copy and some notes taken during previous costruction.
Thanks for explanation,

best regards,
Vd
