The only way for the mod to affect the track is if I were to apply the shaders to the track if you know what I mean.
Shaders don't just work by having them in the file.
Each shader has to be applied in text form to the car for it to work, so if it's not applied to the track the same way then there is no way that the cars shaders can have an impact on the track.
This would be an example:
//============================ Car Body ======================================
INSTANCE=SLOT<ID>
{
MOVEABLE=TRUE
<LOW> MeshFile=Pagani_SHAD.GMT Render=False CollTarget=False HATTarget=False ShadowObject=(Dynamic, Solid, 128, 128, GT3_AMBIENTSHADOW.dds) LODIn=(0.0) LODOut=(80.0)
<MED> MeshFile=Pagani_SHAD.GMT Render=False CollTarget=False HATTarget=False ShadowObject=(Dynamic, Solid, 128, 128, GT3_AMBIENTSHADOW.dds) LODIn=(0.0) LODOut=(100.0)
<HIGH> MeshFile=Pagani_SHAD.GMT Render=False CollTarget=False HATTarget=False ShadowObject=(Dynamic, Solid, 256, 256, GT3_AMBIENTSHADOW.dds) LODIn=(0.0) LODOut=(200.0)
<MAX> MeshFile=Pagani_SHAD.GMT Render=False CollTarget=False HATTarget=False ShadowObject=(Dynamic, Solid, 512, 512, GT3_AMBIENTSHADOW.dds) LODIn=(0.0) LODOut=(300.0)
I rarely see flickering, now and again I see this and mostly with AMS Brazilian tracks.
My own track updates don't have this problem, I honestly don't know what the cause is but I do know it's not the car.
