Import failed: Struct.error (Byte loop causes required buffer to increase)

[Endlosschleifenet]

Hey, I tried importing some models, some models work, some don't and this happened

[Horizon1173]

i have the exact same problem. i tired to import the Montana and it gives me that exact error

[Endlosschleifenet]

I fiddled around with the code, I changed the values of <3 to stuff like <12 and <256 so on, and the buffer seems to scale with this, so if the value was 3, it is 12. 12 gives 48 and 256 needs 1024. As you can see the buffer required is scaled with this by 4 for some reason.

so is it in the fix in the repo or do i have to do it myself? 👍 )

I've been looking through some forums the problem is that the byte are looping hence why if you bring up the number it just requires more bytes. although that's all i could find

[Endlosschleifenet]

Ohh that is really interesting. Well maybe there could be something that would fix this, I will try and find something

[Endlosschleifenet]

I changed the code, and it seems to have in fact lowered the required bytes from 12 to 4! I am still looking around and I'll update when I find some more stuff

[Horizon1173]

did you find a fix to the problem ?

[Endlosschleifenet]

Not yet but I am busy for a while, however i will get there.

Since I also got the same problem, I started testing the code. What I found out is that the script is looping outside the file size. So I added a check, in every for loop which has a .read() function in it, that looks if the reading "cursor" is outside of the filesize and then breaks. For now my modified script imports the file, but the result is a complete mess. I don't think this is what the importer is supposed to do.

I think they might of modified the .GEOMETRY files making it cause theses errors. its not out of the realm for developers making new modified forms of the same format. Paladins uses a Modified version of a TFC file so converters end up creating a huge mess of a DDS format.

Yesterday I found some Scripts in Matlab that claims to be able to extract .geometry files to .obj files (Geometry-model-extraction-demo). In the description they say: "The first functional version is done. It only works on old .geometry files extracted from 0.10.2 to approximatively 0.11.3 becasue WG has started to encode the models with mesh optimizer. Although the file extention remains the same, the data are now coded in another way.", so you are correct.

so is there anything that we can do now?

i meet the same question now.My blender version is 3.6.0,i have tried the 3.0.0 and 2.8.0 but all do not work too.How to solve it?Or is there other way to import and export the .geometry files in the Blender?
