Use this instead:That is for sun specular on track, what if I want to darken the asphalt
INI:
[SHADER_REPLACEMENT_...]
ACTIVE = 1
DESCRIPTION = change brightness shader settings
MATERIALS = material_name_here
PROP_... = ksAmbient, 0.3 ;use proper values here
PROP_... = ksDiffuse, 0.3 ;use proper values here
But before you ask for every single thing that can be changed with config, please have a closer look here:
Home
Configuration files for Assetto Corsa Custom Shaders Patch - ac-custom-shaders-patch/acc-extension-config
Or just examine other track configs how they do it.
You can for example use MESHES names instead MATERIALS names.
Some things have to be done with SHADER_REPLACEMENT, some can also be changed with MATERIAL_ADJUSTMENT, etc.
So, reading the Wiki, will help you a lot more... hopefully...
