Gran Turismo 4 Tracks 3d models request

[Mustafa]

Hi,

My name is Mustafa.

I`ve been looking for long time for 3d tracks models from Gran Turismo 4 but without luck to find any or respond from members.

May I ask if someone could help to to get these 3d file tracks? especially (Assisi / Città di Aria). I want to export it to 3dsMax (for rendering).

I don`t want to be banned if I`m posting in the wrong place.

Thank you in advance and I appreciate any help.

Regards,

Hi,

that's no surprise if you don't provide a track sample.

Looks like someone already mapped out most of it:

Hi,

Sorry I don't know what are these or how to use.

You need the 010 editor to make use of it. (The free trial version expires after 30 days. So it would make more sense, imho,  to convert the bt templates to bms. That's on my list since years.)

If you're asking for models, that's against the rules.  If not, then amend your post with some proper context.  This thread is about tracks.

@Gcr27 if you want get the cars use this one.

Just drop car file over the exe and you'll get the car in obj format. But it export only car, no wheels or breaks. Older tool was able export at least breaks.
