MHWilds High Quality Photo

Features

• Allow using WebP image stored on your computer to overwrite quest result background image or photo mode image: These override photo mode images can be upload to your hunter profile (please respect the TOS, don't post corn)
• Allow high quality quest result background, with ReShade applied: Requires ReShade with Add-on. The background will already have ReShade applied and can be screenshoted directly using Steam F12

Requirements

Must

• REFramework: version after 3f9086. Click the number jambo to download the compatible REFramework
• ReShade with Add-On from version 6.x (the one in the red box below)
  • This is for high-quality image capture
  • If you only install normal ReShade, the override image options are still available, but the high-quality capture will do nothing

Optionals

• SlowMo Mod: really recommend you to install it. The mod may have some problems capture the quest result output if this mod is not present, but I have tried handle those problems

Warnings

HIGH QUALITY CAPTURE MODE: HDR: IS NOT OFFICIALLY SUPPORTED (YET)

• I don't have a HDR monitor, but I have tried to make the mod work with high quality capture
• Override image only users: you are good

Installations

1. Install REFramework: version after 3f9086

2. Install ReShade WITH ADD-ON: download this version, notices the caps lock

3. Download and extract this mod in the same folder as your MonsterHunterWilds.exe

MOD Q&A

What is the game doing

• The game uses WebP to store quest result background and album photo mode image
• The two discoveries below are from my own testing. Your feedback may change this Q&A

For album image:

• The game forces your album image to be a WebP, file size <= 256KB
• The game force your image resolution to be of 1920x1080
• Because of these two facts, your album image is always compressed to the brim. The final WebP stored to your save data is usually 30-50% of original quality

For quest result image

• The quest result image is 1920x1080 on 16x9 mode and 2560x1080 on 21x9 mode. File size <= 256KB. The final WebP stored to your save data is usually 30-50% of original quality

What I have done

• You can override your photo mode result, quest result background with your own image: For now, try to keep the file size <= 256KB and image resolution of 1920x1080. For quest result image, be wary of the resolution (1920x1080 on 16x9 mode and 2560x1080 on 21x9 mode)

• Quest result background/hunter highlights background:

  • Image is lossless now. But your result background need to scale to fit the requirements. On 4K screen, you are basically being scaled down to 1080p
  • Image will preserve all the ReShade details applied to it:
    • The mod will hide the game UI for few frames, do a ReShade screenshot and then inject the screenshot into the game.
    • When the quest result screen is displayed, ReShade effects are turned off, so that the captured screenshot may display in correct colors.

Why the fixed 1920x1080 or 2560x1080 size?

• Your image will be store in a texture object to show to the screen. If the image and the texture object's dimension does not match, the game will either show a corrupt cat icon, or use a backup image to show to the screen (I have not digged deep into the backup part yet)
• The information of that texture is being stored in an asset file. There are two textures in fact, one for 16:9 and one for 21:9
• These two asset files are (used in GameSystem.scn):
  • GUI/ui_texture/tex_render/rtt990000_00.rtex.6 (offset 0x10 and 0x14 is width and height, 16:9)
  • GUI/ui_texture/tex_render/rtt990000_10.rtex.6 (offset 0x10 and 0x14 is width and height, 21:9)
• Can I overwrite these tex to allow more high resolution? I think so, but I will only try if there's demand really (I'm not familiar with asset modding yet)
