problems ripping tracks with a8tool

[testing4562145]

i wanted to rip the entire track out of like the area 51 track, but when i put the converted models, tracks like barcelona have glitches in their models, i have put the image of the glitched model, uv and the files of the area 51 track, they also have weird normals

 

original models.zip

another example is with venice, in the area with the ramp, this is what the uv map looks in pig2fbx, and then the a8tool one, no model differences, only uv map

ven_props_zone_sm.zip

[testing4562145]

again here, posting all of the models from ftt (terra 9) https://mega.nz/file/YBljVTrC#f8pPWA1DW04JZEb1eWqLA3eTdCZpBDjBqJ8Dy7w_zws

i can rip tracks from older versions with pig2fbx, but the road uv mapping is inaccurate

if anybody wants to try converting or fix it, i have a8tool here a8tool.zip

it's just the tracks and garage that have uv mapping issues and some other models, the cars and bikes work

Well,, this all confuses me a little bit. First off, there's two different compression algos used for the pig files, lz4 and zstd.

You can differentiate between them like so: zstd compressed files contain these signature (seed) bytes: 26 B5 2F FD (where it's 28 instead of 26 in zstd v 1.2.0 afaics).

The pig files which pig2fbx (from Chipicao) can decompress have lz4 compression. Since the source is available you just need to give 1 (one!) sample where the uvs don't match and a coder could try to fix it.

How should one fix it whithout the sosurce code? You have to wait for Bigchillghost (not sure whether he'll dig up this again 7 years later.)

I tried to decompress pig files with zstd.exe of different versions, nothing worked.

edit: the problem was that I compiled the exe Compiling libzstd.dll, that worked like a charm..

https://mega.nz/file/dVVBjaSa#ZXEii9DKVw8ZMUX3J_8eeNLEUcpRIoPEWmrvbtt5lfQ i have the road models that have uv mapping issues, they were taken from 1.8.0, these are from nevada and sector 8, but have the same issues for other tracks (great wall, alps. french guiana, san diego, etc), as such the only ones that didn't come with issues were tokyo, azure coast and venice

thanks! What I meant was which pig file exactly (name?)

uvs of stones etc are ok

ok, you meant the road

But isn't that supposed to look like as it should? (how does the (diffuse) texture look like?)

i have the textures, but they are very big and are transparent, extracted them from the windows version, i removed the transparency as it would look weird

 texture for the dirt parts

 texture for the main roads, there are a couple of them

and then here are the sector 8 road textures

[testing4562145]

for sector 8, some portions of the tracks have the incorrect uvs, while some like the tunnel and other parts are fine

[shak-otay]

Ok, then

this is the obj model for nevada race 08 props

As I wrote before, the uvs seem to be ok to me. You might find the suiting textures and try to apply them

(If you need another model feel free to ask.)

As soon as you find distorted uvs I'd need the model's filename and the textures you tried on it.

Then I'll check Pig2FBX concerning the uv creation. 

btw: I converted the ASCII FBX file to obj with Noesis, since Blender imports binary FBX only . (It were possible to convert ASCII to binary FBX using Autodesks free converters, iirc.)

[testing4562145]

for the distorted uv maps, they are "nev_race_number" (without props, decal, vegetation or the other stuff), for sector 8 it's "ber_area_number_road", i tried to apply the road textures but they came out weird and sideways

iceland roads.zip the iceland track, but only the road itself

 this is the uv map of all roads of nevada, except the tunnel since it has the right ones, it shouldn't be like this, the other uv map is weird, as it is flat

checked nev_race_09.pig

UVs were not distorted but displaced and too big (> 1.0 for example). As a simple  workaround you can move and resize the uvs.

[shak-otay]

I decompressed a zstd compressed file, arx_area_005_tunnel2.pig, but I'd need the tunnel texture to check whether I found the correct ones.

arx_area_005_tunnel2

 

btw, the vertex count, 13711 maybe wrong, since in the fbx from a8tool the tunnel has 13722 vertices.

the uvs you found on the tunnel were the lightmap ones

Edited September 1 by testing4562145

Is there lightmap textures?

Thanks for the textures but none of them fit the uvs:

Thanks, seems to work:

lightmap texture for the tunnel

Just in case you want to check it for yourself:

arx_area_005_tunnel (without gateways and such)

btw: the face indices were taken from the fbx file created by A8tool, so don't try to get them using hex2obj
