I haven't really got the controls dialed in or played the game much, but thought I'd share a couple tips for making Le Mans 24 more playable.
Every single game added to a driving cab is an accomplishment.
First up, during the rainy part of the stage, the fog isn't emulated properly and blocks our view, so lets get rid of it completely.
The glsl shader file attached to this post has been modified to disable fog, per instructions posted by Bart on the Supermodel forums:
http://www.supermodel3.com/Forum/viewtopic.php?f=3&t=85&p=712&hilit=fog#p712Put the .glsl shader in your supermodel directory. To use it, add -frag-shader=nofog.glsl to your command line.
supermodel.exe lemans24.zip -res=1024,768 -fullscreen -frag-shader=nofog.glsl -sound-volume=50 -music-volume=170
Second, the shifter works differently than other games.
To get it to work properly, the controls must be modified manually in supermodel.ini
InputGearShiftUp and InputGearShiftDown shifts up and down through the gears on games that originally had 4 speed shifters.
They do not correspond to the up and down on Le Mans 24.
The upshift and downshift should be mapped to InputGearShift1 & InputGearShift2.
The following is my mapping (for all games) that allows either my shifter or paddles to be used.
It also makes neutral work properly.
InputGearShift1 = "JOY2_BUTTON3,JOY1_BUTTON1"
InputGearShift2 = "JOY2_BUTTON4,JOY1_BUTTON2"
InputGearShift3 = "JOY2_BUTTON5"
InputGearShift4 = "JOY2_BUTTON6"
InputGearShiftN = "!JOY2_BUTTON3+!JOY2_BUTTON4+!JOY2_BUTTON5+!JOY2_BUTTON6+!JOY1_BUTTON1+!JOY1_BUTTON2"
InputGearShiftUp = "JOY1_BUTTON1"
InputGearShiftDown = "JOY1_BUTTON2"
JOY2 is my act labs shifter.
JOY1_BUTTON1 & JOY1_BUTTON2 are the shift paddles on my Logitech MOMO that I wanted to use with this game.
When no gear shift buttons are pressed, it will register neutral.
It should work the same with a G25 or G27, provided the correct JOY and BUTTON numbers are substituted.
