Fixed Depth Detection in GTA V

Crosire found out that we supposedly got a log depth buffer in GTA V. However, the typical logarithmic function to retrieve depth values only returns the depth values of a very limited distance due to a strong fall off which would drastically limit the possible focus range. Fortunately, combining the typical function with a correction applying fall off dependencies solves that problem though I still need to adjust a few more values

Anyway, here is the current result, showing casing near and far DoF (keep in mind that the new algorithm allows to push back the far DoF much more than in the video)

Tuning Palette

Since there have been quiet a few discussions lately about look up tables, I implemented a tuning palette shader that accepts ENB palettes so you guys can apply your favorite palette of the ENB injector
This shader will also allow a few more options than just applying an ENB palette.

Applied this ENB palette with the TuningPalette shader


to GTA V

Tuning Palette #2

"To everyone its own"; As requested, I added an algorithm that applies the old Quake palette instead of an ENB palette. More options for this shader will follow

Some more options...

...GTA 5 goes vintage

Eye Adaptation / Ambient Light Correction/Perfection

Just wanted to correct some of the eye adaptation algorithm for ambient light and ended up to have a result that pretty close to reality (at least in my silly eyes )

Gr8mmFilm Shader

As requested and still WiP

Pseudo DoF Option

Added an additional option that allows to activate DoF shader by using a pseudo depth buffer for either online games or those that do not have any depth buffer.

Here used on GW2

Motion Focus

For all that are familiar, this will work similar to the Skype's smart camera/motion focus on XBoxOne. The algorithm is not that smart yet and the transition not as smooth due to it being still very early in development but it is finally possible for you to see in which (obvious) direction it is going

Motion Focus #2

Now I am certain it works as originally planned.
The smart camera/motion focus is already implemented and it seems to have decent performance in that early stage.
Whats left is some more smoothing, especially at the beginning and end of the focus.

The calculated direction of motion you can see in the following video when watching the red spot position, relative to the center (green spot).

Motion Focus (Final)

I am finally done with the motion focus shader after struggling with performance, smoothness and accuracy. However, the results are worth the pain as it excels in all these categories

In the following video you can see DoF, AL and motion focus in action while sticking close to 60 frames per second in DSII (while recording and using an old GTX 570) .


The shader is running in debug mode. While the two dots in the center of the screen display the same thing as described in the previous post/video, the 4 bars on top of the screen represent the motion intensity distributed on screen. The red bar represents the top-left, the green bar the top-right, the blue bar the bottom-left and the yellow bar the bottom-right part of the screen.

ReShade Framework Mediator

So, as promised, here a quick look at the current progress of the configurator/mediator for the ReShade Framework. Though I have some experience and "assets" from the previous GEMFX configurator, many things have to be implemented from scratch. Same as the ReShade Framework itself, the mediator needs to be flexible and simple to use for both, user and developer. Therefore, all elements will now automatically be generated (and placed).

In the following you can see that reading from Framework files is almost done. I used several test suites with test values for shader/effects and their variables. What you see is generated automatically and already fully adjustable.


Note that in the picture above not-automated elements of the mediator/configurator are not displayed, since this picture should only showcase the automation results.

There is still quiet a bit left to do, especially for writing values back to disk, but everything looks very feasible now

ReShade Framework Mediator #2

Finally another official progress post on the configurator end
Its still in its raw form but the core automated functionality is implemented:


The tool automatically...
...generates a configuration interface from arbitrary configuration files
...generates entire configuration files from its freely modifiable configuration interface
...generates an effect ordering list in which it smartly groups dependent effects
...effect ordering feature combines both, activation and reordering of individual effects

Still lots of stuff missing as you can see but the automation part is mostly done (of course bugs will need to be fixed).

ReShade Framework Mediator #3

Added the preview feature (maybe a few of you know it from GEMFX) but using simpler rendering that should work much butter (though being less responsive).

ReShade Framework Mediator #4

Sorry for literally spamming this thread with news but having all this space on the main mediator page there is just another automated feature that is in works (just see for yourself ):

ReShade Framework Mediator #5

I am almost done with the Mediator. Those are the things left to do:
- Some more layout fixes (automated)
- Local preset file browsing (automated)
- Filling spaces with additional information
- Most likely an additional tab page for each suite (automated)
- Port of remaining cfg files (which Ioxa is working on currently )

The goal is to finish this weekend but the release is up to crosire's timing on ReShade 1.0

Old LogDepth vs New LogDepth Algorithm

What I am currently working on.

(current/old - already further distance than linear)


(conceptual/new - even further stretch of values)

MotionLight

Starting to implement the requested motion blur effect of light
I know, it took me quiet some time to get started

DaVinciCode_(WIP)

A new algorithm that I am currently working on and which is inspired by the an-isotropic diffusion effect in photoshop:

Vanilla


HighQuality, LowCost Paint Shader


The high quality is especially noticeable with lower effect strength when comparing to other algorithms (including photoshop) which usually produce artifacts. This and its high performance makes it a very useful (and playable) effect and further allows it to be used as a sort of anti aliasing effect.

With a little help of wordpress I created a simple developer blog which I will use as "further reading" material to the updates I post here. It will basically provide you with in depth explanations on how certain ideas work and how they can be or are approached by me, you or anyone else.

Novel Lens Flare Algorithm_(Conceptual)

As a foundation for future implementations I came up with a new algorithm for a very smart/dynamic and performant lens flare format. It involved quiet a bit of math though

Yet Another Novel Lens Flare Algorithm_{(Also Conceptual )}

With this algorithm, I am trying to increase the responsiveness of generic lens effects.
