For some reason, when I want to apply some Megatron preset, it doesn’t activate properly with HDR.
It only happens to me with the MegaBezel Megatron presets, since when I use Megatron by itself everything goes perfectly.
Has anyone had this problem?
I share a couple of photos. Thank you for your answers!
@HyperspaceMadness I didn’t want to ask about this in the vertical overlay thread, but what are the settings he is using to get the reflections on the overlay? Right now I only have them on the inner bezel.
You have to ensure that if you’re using the Vulkan Driver:
Make sure HDR is enabled in RetroArch.
After you load the Mega Bezel Megatron Preset, Make Sure you toggle the SDR/HDR parameter to HDR in Shader Parameters.
After that, you have to adjust your Peak Luminance and Paperwhite Luminance settings according to the Sony Megatron Color Video Monitor setup instructions.
Before you do all of this, be sure you’re using the latest Mega Bezel Reflection Shader 1.15.0+
Mega Bezel is updated to V1.16.0_2023-12-10

Thank you for your response Cyber, I really appreciate your participation here, your presets combined with Megabezel were the gateway that led me to participate in this forum. Very good work.
Regarding the RetroArch settings, I have everything as you mention, I use Vulkan for almost everything, HDR activated (working perfectly with the Megatron default version in the hdr folder) and with the appropriate luminance so that it looks ideal before my eyes.
The problem is that when I load the Megabezel settings with Megatron, the HDR is not applied correctly, I can identify it by pressing F1 and seeing how the menu color remains faded, when it normally changes when using a Megatron setting.
I’ll do a few more tests and comment on the forum to see what happens.
Has everything worked well for you? I don’t know if it’s of any use, but I want to mention that I use a 4k monitor with BGR subpixel division. I have noticed that a large number of participants use an OLED TV.
Greetings! 
This sounds like you’re using an older version of Mega Bezel Reflection Shader.
You have to manually update to get to version 1.15.0 or now 1.16.0.
Remember all Mega Bezel Megatron Base and Root Presets use Megatron SDR Mode so you would have to manually switch them to HDR Mode in the Shader Parameters.
You can try these sample presets I’ve included which have the correct HDR toggle enabled in the Shader Parameters.
They have to go into the “Shaders” Folder. Post your Peak and Paper White Luminance settings as well.
You were right! I just updated to the version and now everything works without problems (photo attached)
I also attach my adjustments to the peak luminance of my screen. It is a monitor with DisplayHDR1000.
I usually set it to 1000 as peak and 700 as PaperWhite.
Thank you very much for your support Cyber!
Also many thanks to HyperspaceMadnes for your splendid work with those realistic bezels! I love it!
So, the Hi-Res scanlines are only for use with smoothing, and won’t work without it?
Actually, please disregard. I figured out what was going on. When I first started using MB, I had turned down global reflections to just get a subtle relection, and had turned it down so far I wasn’t even seeing the fullscreen glow, etc… It wasn’t until I saw that video that I realized I was missing a lot of the effect. So, I’m going back through and adjusting individual elements of the reflections so I can enjoy it more. Late to this party, but it looks great. 
Thanks there are also Megatron presets in the Variations folder for both SDR and HDR modes
Yes this is only for SMOOTH-ADV or SUPER-XBR. Basically what high-res scanlines does is keeps the base scanlines vertical dark/light pattern, but reveals the full resolution of the layer coming into the CRT shader,e.g. ScaleFx at 3x core scaling.
One of the things that I’m pretty sure @far327 is using the reflection mask image to modulate how much reflection appears in different places. I’ll probably put in some more features to control where the reflection appears OUTSIDE the bezel (Currently the reflection ONLY appears inside the bezel area, so you have to make the bezel larger to encompass the area you want the reflection to appear).
Yeah that is essentially what I am doing. Sorta the easiest work around I could come up with. Additional controls for this would be great! They may already exist in the shader params, but I was looking for a way to adjust the reflections with tilt in mind. Would be useful for overlays that have more intricate cabinet angles
Thanks. I was able to get a better effect by just bringing up the “fullscreen glow” (I think it’s called) into the mix and then balancing everything. I kept it fairly subtle still, but it gives a nice, dramatic pop to flashes, etc in the arcade games.
Thanks! Is there a way to find the glcore for the nintendo switch?
If it isn’t listed then it isn’t possible.

So is this something that was there in the past then disappeared, then came back? Or is this a new thing?
Hi all. First of all, thanks to @HyperspaceMadness for the incredible shader =) I have a question about it, and I’m unsure if this is the right place for this, since it’s a bit specific.
I’ve been using the Duimon pack on my Steam Deck, and it looks incredible. But one of my questions is, since the Mega Bezel shader “moves the screens” of the games (not sure how to describe it), it’s difficult to use it with Nintendo DS Games.
I’m trying to use the touch screen of my Deck with Desmume and MelonDS but since the Mega Bezel will move the game’s picture, the touch screen will get displaced as a result (I really do hope my sentence is understandable).
I was wondering if there was any way to fix/compensate this?
There have been some changes recently, specifically with MelonDS, to address this issue.
Make sure you are using the newest version of the core.
I don’t have a touch screen, but enabled “touch” for touch mode in the core screen settings and it seems to work with my vertical presets.
Oh, didn’t see you were on this thread, I shouldn’t be surprised, thanks for the Shader Pack project =) Awesome news, thanks, I’m gonna try this later today see if I can find how to set this up =)
Allright so I tried again after updating my cores and : no dice. I didn’t find any settings that would help me.
Since I have to set up my RA Aspect Ratio to “full” in order for the shader to take up the whole screen of my Deck first, when viewing the raw picture of the emulator (without any shader), MelonDS outputs a horizontally streched image.
Now, this is not an issue with the shader visually, since it “puts it back” to its adequate aspect ratio.
The issue is, MelonDS is of course not “aware” of this, so the result is that the whole range of the touch screen for it is the ENTIRE bottom half of the screen. This is, of course, especially an issue with horizontal pointer movements.
Hope I’m being clear, but if any, I can capture and provide a video of the issue.
