Hi
Im trying to use the koko shader file with duimons shader presets. So im testing with the Nintendo Snes preset in duimons pack.
Ive added in a line to the STD_Bezel.slangp file that points to one of the koko-aio slang files.
but its not changing the image, its still using the one from duimons i think. What file to i need to edit to make these changes ?
Sorry, new to all this
Yeah, I’ve seen you opened a bug report to github duimon’s repo too. However I think the right place is:
Hi i’ve never used koko before i’m seeing loads of superb ghouls and ghosts screenshots…what is the preferred koko preset for a 1080p non hdr screen?
what is the closest setting to this?
It’s ok I’ve found a preferred preset 
(awesome work on this!)
What preset ? 
just went with balanced and changed the ambi slowdown to 30 so it was a bit more reactive
I switch between Koko and Guest (via megabezel specifically) a lot and I really like both, but whenever I switch to my guest presets I always miss the ambilight effect. Is there any way to use the ambilight effect from koko-aio shader with other shaders?
Unfortunately Megabezel would need to implement it.
Maybe uborder shaders?
ooh thanks for pointing towards uborder. That was was exactly what I needed. I have almost exactly recreated my megabezel guest preset in uborder.
Hi koko, it seems the reflections become “jagged” when using the tilt feature:
without tilt, they look good and smooth:
Thanks!
Indeed reproduced, but I’ve a workaround ready.
I’ve just to test the performance impact before merging.
Also, I spotted that the vignette/pillow/screen uniformity thing does not follow the tilt “perspective”, so I’ll fix that too.
Workaround applied and vignette perspective fixed, you can pull from the git repo.
Pillowing effect still needs some attention, instead.
tldr:
If you update from the github repo and see the slotmask disappear from your tweaked personal presets, divide “Clears hives patterns (slotmask)” by "Phosphors height min->max gamma"
Why?
Regarding the “clear hives patterns” parameter, used to mitigate slotmask glitches at low resolutions:
…there has been some changes on the development repo that requires you to modify any preset using it.
Shipped presets have already been tweaked, but if you need to, the formula is:
slangp parameters:
new PIXELGRID_Y_MASK_OFFSET_DEHIVE = old PIXELGRID_Y_MASK_OFFSET_DEHIVE / old PIXELGRID_GAMMA_H
Human readable:
New "Clears hives patterns (slotmask)" = old "Clears hives patterns (slotmask)" / old Phosphors height min->max gamma
This change not only provides a small performance improvement, but makes the dehive appearance independent from the Phosphors height min->max gamma parameter, so it is a win/win
If what you are trying to do is change the image, you will need to save a preset and add a new background image line to it.
You would really be better off starting with one of kokoko’s presets unless you need one of my custom bezels.
These, and my custom backgrounds, are what my project is all about.
Hi there what’s currently the best way to add your own backgrounds? Thanks 
Uhm, I think the easiest way is to load the preset you want as a base in retroarch, then save it as a simple preset.
Open the saved one with a text editor and add the line:
bg_under = /path/to/your/image.png
and
bg_over = /path/to/your/image.png
Save and load the modified preset.
From there on, you may need to align/zoom the picture.
Search for “Backgound image:” in the docs, for additional details:
Ok brill thank you… does it work well with the wildcard system?
I never tested it much, but there is no reason why not.
In that case I’ll go through the uborder presets I have and swap em over to koko just to see how they look 
… see if I can get the ambi working over the bg the same … I think the uborder use the standalone koko ambi iirc.
