Hmm, it's right of course that GP4 modding is quite slow and the difficulties to bring you a full track editor adds to this.
Without going into too much details, tracks are composed of multiple files and the most important one is track's physical definition stored in the .dat files.
I can't by myself tried to change every byte of these file to know what they does (because, that's the only way to understand how to create/modify tracks) and that's why i built the .dat part of 3DEditor.
The goal was to give you a full access to all the file, affording everyone knowledge already gather by GP3 track makers and an easy way to edit the files graphically without having any hexadecimal knowledge.
So Beostar, you know what you have to do :
Just open a dat, change 1 and only one value, save the file and try the game to see what changed. Anybody can do this.
Of course it will crash GP4 sometimes but copy/paste original .dat file will make everything ok again.
About future, and appart tracks physical side, i'm currently working on a much better .gp4 files editing allowing more modifications in materials and 3D objects properties as Normals, and every other datas stored in .gp4 files.
And much can be done in the graphical area, better textures, new objects, better mappings...
Car mods are still alive and independant data modification bring by Madman in GP4Tweaker will allow much more things in future (different wheelbase / car for exemple).
So, it's obvious that we might never see any peace car real feature in GP4 but many great things are still in front of us.
