UPDATE v0.6 (free) (Patreon)

All major new changes in update v0.6 concern the Patreon version and the Service Park, most of all, the new function of dynamically created reshade presets depending on what weather you selected, what stage you're on, what surface you're drifing on, the time of day, whether you're in a replay or driving, etc.

However the FREE version also receives some love, with some needed bug fixes to some stages previously not working (see changelog) but also a reworked reshade preset with better POV headlights handling and NO MORE MANUAL RESOLUTION issues anymore!
The preset will now set the correct resolution to all textures (POV headlights, indicators, help) automatically to your in-game resolution.

The downside to that is however that you need to rerun the reshade.me installer to download some new shaders for the new preset to work as intended. The manual has detailed instructions but here is the gist:

the following shaders need to be selected when updating the new shaders, with some of them having to be selected manually:

Legacy effects:
AmbientLight.fx
Bloom.fx (you will need to select this one manually)
ReflectiveBumpmapping.fx (you will need to select this one manually)
FX Shaders by Luluco250
AdaptiveTonemapper.fx
Shaders by brussell
EyeAdaption.fx
qUINT by Marty McFly
qUINTsharp.fx
Color effects by prod80
PD8003_Shadows_Midtones_Highlights.fx
PD8004_Saturation_limit.fx
PD8006_Luma_Fade.fx
CorgiFX by originalnicodr
StageDepthPlus.fx (you will need to select this one manually)
GShade-Shaders by Marot
PirateDepth_DOF.fx

But this should be the entire extent of the hussle of using reshade in the free EVO version now. No more manual resolution changes, etc.

Still, optional, are the indicators to indicate whether your post process effects (POV headlights, bloom, DoF, Reflections) are active. If you want to use them you need to open the reshade window in-game (NumPad0) find them in the shader list, and right-click them to set a shortcut to sync them with the respective effect:
alt+L for POV Headlights
ctrl+L for POV HighBeams
ctrl+B for bloom
ctrl+A for DoF
ctrl+R for road reflections
! and remember ctrl+H opens a help screen !

Please keep in mind that the free version of EVO mainly focuses on the particles, weather and retextures, as they were the original meat of the content of the mod. All other functions (reshade, clouds- and audio randomizers) in the free version are toned down approximations from the Patreon version, since they simply CAN'T be reproduced without the functions of the Service Park.
(see the manual for more information on how to work the clouds-, audios- and the EVO reshade abilities in the free EVO version)

To update: Download and extract to merge its Maps folder with your existing one in your RBR root folder. This will apply all of the updates' content.
++ ATTENTION: You will however have to reinstall some shaders through the ReShade.me setup (see above or the manual)

New to EVO: download and install the full mod from here.
