Converting cars from GTL to GTR2

Does anyone know of a GTL to GTR2 car conversion tutorial ? I've done plenty of the simple "renaming" conversions from GTR to GTL, but when I tried today to convert a Porsche 930 from GTL to GTR2, no luck. Is there one major difference I'm overlooking going from GTL to GTR2..?

Must change .gtl to .gtr and do the same in the. Cases for stex.glt, talent.gtl and the renamed and stex_gtl.gtr talent_gtl.gtr

You forget to change the .cas lines MasFile = xxx.gtl in MasFile = xxx.gtr

I've use a traductor, he lots a part :s

Thanks Guys !!! I had stex and talent.gtl.gtr instead of talent_gtl.gtr, replaced . with _ and the car is in game now, Thanks again !!!!!!

Sorry for bringing this up I must me stupid but how exactly do you do this?

I use geditor from Nogrip to convert .gtl files to .gtr
I'll use a TR4 "skin" for an example (I already converted the mod)

the car SA66 skin has the following files...
SA66_SIM_GTC_TR4.bik
SA66_SIM_GTC_TR4.car
SA66_TEX.gtl
SA66_ULTRA_TEX.gtl
Triumph_tr4.cas
TRIUMPH_TR4_CPIT.gtl
TRIUMPH_TR4_MASK.gtl

to get the name correct I use "rt-mouse properties" copy/paste the filename.
Using geditor use File "Open" and go in to you computer directory to find where you have you car.
The program normal does not "see" the .gtl file extension so you use rt-mouse properties to copy
paste the complete filename for each .gtl file Then use the "Save GTR file as" command to edit
the "L" to "R" ... Now you should have an extra file in the directory. Do this for each .gtl file

SA66_TEX.gtl
SA66_TEX.gtr
SA66_ULTRA_TEX.gtl
SA66_ULTRA_TEX.gtr
TRIUMPH_TR4_CPIT.gtl
TRIUMPH_TR4_CPIT.gtr
TRIUMPH_TR4_MASK.gtl
TRIUMPH_TR4_MASK.gtr

In the .car file use Notepad to change the class to the class you want to add in GTR or (in my car-P&G) to
classes="SIM_FULL, SIM_GTC, SIM_GTC65, SIM_ELI, SIM_GTCTC65, SIM_NIGHT, SIM_NOLONG"
to P&G over 2 lite class...
classes="GTO2"
Save the change in notepad then close the file

In the .cas file use Notepad to change


MASFILE=TRIUMPH_TR4_MASK.GTL
MASFILE=TRIUMPH_TR4_OBJ.GTL
MASFILE=TRIUMPH_TR4_TEX.GTL
MASFILE=TRIUMPH_TR4_CPIT.GTL
MASFILE=TRIUMPH_TR4_WHEELS.GTL
MASFILE=STEX.GTL
MASFILE=TALENT.GTL

to P&G
MASFILE=TRIUMPH_TR4_MASK.GTR
MASFILE=TRIUMPH_TR4_OBJ.GTR
MASFILE=TRIUMPH_TR4_TEX.GTR
MASFILE=TRIUMPH_TR4_CPIT.GTR
MASFILE=TRIUMPH_TR4_WHEELS.GTR
MASFILE=GTL_STEX.GTR
MASFILE=GTL_TALENT.GTR

for GTR use the following for the last two lines..
MASFile=STEX.GTR
MASFile=TALENT.GTR

If you are converting a complete mod you also have to make sure you have the sound file and
the .aud file in the mod to call it.
The .tyr needs to be include in the mod since it is specified in the.hdc file--
my TR4 calls for

TireBrand=63_TR4.TYR

Each of the files listed are opened and edited with Notepad.

No need for geditor to convert gtl to gtr files.
A plain extension rename works fine from .gtl to .gtr in windows
+ associated .cas file edits of course.

yep, the .GMT (3d mesh file format) and texture logic materials / names are same for GTR2, GT Legends and for the free BMW M3 Challenge game.
no need even to rename the car file packs (.GTR, .GTL or .BMW) to make some quick "conversion test"
however, to set working cpit rpm or fuel warning lights is bit different comparing GTL to GTR2.

all the succes (no CTD) depends only, where the files are stored. every moder / convereter should use the game trace log to fix such issues.
this will tell you what did you wrong
