Colin McRae Rally 3 .TAG and track model files

I know there has been research on the later games, but since this one uses a somewhat different format, can anyone look into these so I can convert the tracks, cars and characters to another game?

The archives can be opened and repacked using iRipper; it's the .TAG and .*TAG models that doesn't appear to be cracked yet.

How complex is the format though?

The TAG/tag archive format is simple.
Here's a BMS script to unpack the TAG/tag files:
tagUnpacker.rar
Do you have problems with the *.big archives?

I don't have an issue with them .BIG files as iRipper can open them anyway. It's the .TAG and related model formats themselves (i.e. .BTAG, .CTAG, .ITAG, .STAG etc.) that are in need of reversing.

Some files actually use the same format as the big files even they're with a different extension, like all the files from your Auspod sample.
Just in case it's needed:
bigfUnpacker.rar
As for the models, it's really inconvenient to extract them with Hex2obj since they're unpacked as different part, also there's some face format that hex2obj can't deal with. But breaking the archive into smaller separate parts can help you research the format easily.

Did you take a look at the samples I attached? I.e. the .STAG and others? They seem to be similar to the .P3D stuff Michael documented here (at least with the header):

EDIT: I've also attached the .CMR mesh files extracted off the Citroen 2CV .big archive here:

No, I didn't. I just take a quick glance on the big archives and made a compatible unpacker. It's the tag format that interests me. And my research on its geometry format is done.

Maybe, since they're using the same magic number.

Hmm, could you walk me through using the importer on that thread if you don't mind?

Doesn't work with my Max version. Hadn't you tried that?

Couldn't seem to get it to work either. :/

That didn't work either. The file open dialogue shows up but importing the Colin and Nicky .STAG files was to no avail.

I thought it doesn't work for you to open files this script was written for. I didn't added support for CMR3 files.
