In case anyone would like to do some more testing:
TREdit for converting tracks and carset to a [EDIT]half single[EDIT] level MIP:
https://nirvtek.com/downloads/TREdit.20250321.001.7z
MD5: 4eb4d4083a9bcbfa4bb35f199c5a1d15
To use this with an unpacked DAT:
tredit <path to unpacked dat> -reduce -convert <output folder>
The ICR2\Tracks\<trackname>\folder should have everything already there apart from the DAT. Copy and paste the contents of <output folder> (just the MIPS really) to ICR2\Tracks\<trackname> overwriting any existng MIPs.
If the source track or carset is packed into a DAT file:
tredit <path to dat file> -unpack <unpack directory>
First zap the dat file in ICR2\TRACKS (leaving all other files in there), copy the unpacked files folder then do a reduction and paste reduced files over ICR2\Tracks\<trackname> folder.
I've successfully reduced Denver, Indianpolis and Riverside 82 as well as Cars2020 and LOLA 1995. I'll post them in a bit.
TREdit also corrects a bug with MIP file processing. The shrinking/resizing capability might be broken. The explode MIP file function should work correctly for all MIP levels.
