=============================================================================================
 * implemented to enbeffectpostpass.fx by kingeric1992 for Fallout 4 ENB mod 0.288+
 *                                                                      update.  Sep/29/2016
 *      for more detail, visit http://enbseries.enbdev.com/forum/viewtopic.php?f=7&t=4721
 *
 ** Only SMAA 1x is avaliable
 *
 * SMAA T2x requires moving camera in sub pixel jitters.
 * SMAA S2x requires MSAA 2x buffer
 * SMAA 4x  requires both of the above
 *
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 * Usage:
 * add
 *              #define  SMAA_UINAME 0  // 1 == use smaa method independently
 *              #define  PASSNAME0   targetname
 *              #define  PASSNAME1   targetname1
 *              #define  PASSNAME2   targetname2
 *              #include "enbsmaa.fx"
 *                                          at the end of enbeffectpostpass.fx.
 * where the targetname(N) is follow up the technique chain and increment to one before, if
 * the last technique is called THISPASS4, then set targetname to THISPASS5 and the rest with
 * increasing index.  ( targetname index "0" is empty )
 *
 * If you wish to have SMAA as standalone effect that doesn't chain after other technique, set
 * SMAA_UINAME to 1 and have the pass index start from empty (which means "0").
 *
 * in addition, you can change internal rendertarget with :
 * (they will be cleard, so change to other texture if any of the default tex is in used to pass 
 * along data, otherwise, ignore this.)
 *
 *              #define  SMAA_EDGE_TEX      texture0name   // default is RenderTargetRGB32F (only require 2bit-RG channel)
 *              #define  SMAA_BLEND_TEX     texture1name   // default is RenderTargetRGBA64 (requred RGBA [0,1] )
 *
 *                                          prior to inclueing "enbsmaa.fx" 
 *
 * Loading multiple times with different PASSNAME is possible (under same name is not recommended).
 *

 *                              Settings
============================================================================================*/

#define SMAA_PRESET      5  // 0 == low, 1 == medium, 2 == high, 3 == ultra, 4 == custom preset, 5 == runtime UI tweak
#define SMAA_PREDICATION 1  // 0 == off, see descriptions below
#define SMAA_EDGE_MODE   0  // 0 == color(quality), 1 == luma, 2 == depth(performance)

**hotfix on typo with rendertarget.

Sep/29/2016
**replace stencil test with alpha, (stencil is not working in previous release, which is causing some extra fps drop)
**various change in macros setup so that the file now use reference SMAA.h.
**added standalone support for enbsmaa.fx (see the demo enbeffectpostpass.fx).
**added constant setting to increase performance if UI tweaker is not required.

A wonderful addition, now there really is no reason to use ReShade

[kingeric1992]

--JawZ--
still, it doesn't apply on hud like Reshade and power armor hud looks pretty aliased.

and it can't handle thin lines (such as power cables in a distance) without some of the 4x subpixel feature.


a demo from smaa doc

[--JawZ--]

SMAA with ReShade, and most other effects that utilize a blur event, causes flickering. So far I have yet to see such flickering being caused when ported to ENBSeries, so that is something I could easily live with, if just to remove the flickering.
SMAA isn't handling thin lines in general very good, from my testing at least.

Just a possible solution, mix in a bit of depth functionality, close depth SMAA x1, far depth SMAA x4.
Not sure how good it would be or how the performance would be affected as this was just a quick "while-reading-comment-post" idea.

Could you send your postpass? I'm having trouble figuring out how to implement it.

[--JawZ--]

The instructions for adding it is in the enbsmaa.fx file.

If i'm reading the instructions correct, this should be how it should look with the default enbeffectpostpass.fx.
I have not implemented it yet myself, so might have done something wrong here.

file update fix typo. (I need to stop doing that!!)

and the place to add it: any where after this.

Code: Select all

//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
// Techniques are drawn one after another and they use the result of
// the previous technique as input color to the next one.  The number
// of techniques is limited to 255.  If UIName is specified, then it
// is a base technique which may have extra techniques with indexing

examples on integrating vanilla enbeffectpostpass.fx

Code: Select all

// if wish to change default render target, need to set here before any enbsmaa.fx includes.
//(currently texture setting is shared between multiple includes, will come up some better idea in future update)
        #define  SMAA_EDGE_TEX      RenderTargetRGBA64     // default is RenderTargetRGB32F (only require RG channel)
        #define  SMAA_BLEND_TEX     RenderTargetRGBA64F  // default is RenderTargetRGBA64 (RGBA requred)

// set sharp amount to 0 to bypass sharpen.
        #define  PASSNAME0   Sharp1
        #define  PASSNAME1   Sharp2
        #define  PASSNAME2   Sharp3
        #include "enbsmaa.fx" 


//adding it to different technique profile in same postpass:
//do not reset texture here. 

        #define  PASSNAME0   TemporaryTarget3
        #define  PASSNAME1   TemporaryTarget4
        #define  PASSNAME2   TemporaryTarget5
        #include "enbsmaa.fx" 

also the notations are only for chaining after others, require modification on enbsmaa.fx if you wish to use it as standalong effect.

Awesome. This was one of the things I was going to try and add. I've been reading as much as I can on writing shaders and trying to get a good resource, but they always seem to be in a different context than how we are using them. Great work by the way and I look forward to seeing what else you can do. Reading your stuff, even the Skyrim stuff, always seems to help me siphon though the noise, sometimes.

[kingeric1992]

Just a possible solution, mix in a bit of depth functionality, close depth SMAA x1, far depth SMAA x4.

it is not that, 4x is not a term of scale, it use some of the concepts from TXAA and MSAA on top of 1x. and those require special resource besides color & depth.

[ibbanez]

Question, can those .dds files be placed inside the enbseries folder, or do they have to reside in the Main folder, along with the .fx files? Thanks.
