- description

Gravel a bit of a mix up of dirt 2 and a number
of cross country point to point racers, similar
to say those in forza horzion and others, how
ever not so polished as the aforementioned games.

Basically the mod attempts to balance the light
dynamics (day, night and weather) plus adds a
little bumpmap in the mix as reduces a number of
effects plus some heavy tonemapping,
see screenshots for an impression.

If you do not like specific tweaks please see 'further tweaking'
for disabling specific shader tweaks.

3dmigoto shader tweaks:
- reduce specular and tint water surface
- remove lens flare
- global illumination tweaks
- reduce lens dirt
- increase transparency and add green tint to windshield car
- reduce density fog haze
- reduce flare bokha effect
- reduce intensity car headlight (more glass visible)
- partial fix snow tracks layer in cockpit and on driver
- partial fix gravel layer outback red layer on driver
- reduce fogged windscreen front in cockpit with rainy weather
- reduce presence watersplash fx

Note(s):
The  package has a customized shader 'upscale.hlsl' which
does some fullscreen tweaks as bump mapping and color modification
see 'further tweaking' if you want to disable it.

Also upscale.hlsl adds a slight curve to the screen.

- install

Copy the contents of the zip file to the install folder of
gravel, the folder which contains
gravel-Win64-Shipping.exe
<drive>:\gravel\gravel\Binaries\Win64\

- optional install

The following instructions are only needed
if you do not like using unverified dll's you can:

download 3dmigoto from:
https://github.com/bo3b/3Dmigoto/releases
download version 1.3.16 and place the following dlls in the install dir of
gravel:
d3d11.dll (64bits)
d3dcompiler_46.dll
then copy `d3dx.ini, ShaderCache and ShaderFixes from the zip file to the same dir aka folder.

note: if you choose to use the d3dx.ini contained in the github package
make sure to set (line 248):
hunting=0
the default setting is:
hunting=1
which sets 3dmigoto to a debug mode.

- verify

After running the game the folder ShaderFixes should
gradually (scene and level dependent) contain the .bin versions:

*) Game capped at 61fps plus fast sync through nvidia inspector

- further tweaking

If you like you can compare the modified shader, ShaderCache contains
the original shader, to alter values.

To disable specific tweaks open the shader from
the folder 'shaderfixes' with a text editor example:
2b147e5ca0b9a1df-vs_replace.TXT

Has a remark on the top line:
// remove lens flare

So if you do not want that to happen
remove the shader from the folder 'shaderfixes'

2b147e5ca0b9a1df-vs_replace.TXT

and if compiled remove:

2b147e5ca0b9a1df-vs_replace.BIN

then restart the game.

All shaders <shadernumber>ps_replace.txt have
a similar descriptive remark. (see shader list)

to disable the effects in upscale.hlsl open
d3dx.ini and goto line 19 alter it from:
include = ShaderFixes\upscale.ini
to:
;include = ShaderFixes\upscale.ini
save and close d3dx.ini then launch the game.
