ToCA Race Driver 3 Potential Track Modding?

[Polecze]

Hello, I would like to Mod Track Collision files in ToCA Race Driver 3 as well as the Track Environment
ZModeler2 allows me to view track mesh (.px files) although i need to rename them to .p3d

as the filter in zmodeler2 was made for working with cars (.P3D) not tracks (the format is simillar, additionally cars require the export of the part.map file, tracks dont have it) 
so the texture mapping basically fucks off and its impossible to export correctly... aswell the filter does not support all game shaders on export

(col.col collision files not supported in this program) 
Back in the days user Nenkai helped me to view them in Model Researcher Program
https://github.com/Nenkai/010GameTemplates/tree/main/Codemasters/Race_Driver_3 
But nothing has been done in the direction of collision modeling and export

The 3DSimED3 tool has ONLY import option of .px track files (visual)
i have tried to look for source code of this to get more info about the .px format but failed
Also, Oleg - the owner of ZModeler has no longer access to the old ZModeler2 modules, and he refuses to work further in this game

Will this ever be possible yet to make an editor to mod the track mesh with collision modding integrated?

ALSO! There's  aib.big archive which cointains .AI cars data and track minimap coded in the file, also it determines coordinates of start/finish line etc etc... In order to fully support track editing this would also need to be resolved
I will attach files from one track - Adelaide Circuit (You can open .big files using iRipper 1.9)

RD3format.zip contains a file released by Codemasters that explains .p3d file, maybe it can help with the .px structure
