What happens
Outdoors the sky is solid white and distant trees dissolve into it. Looking up from the forest floor in Kokiri Forest, 50–78% of the upper half of the frame is near-white (luminance > 235). The overall scene also looks washed out compared with the save-file thumbnail of the same area, which looks correct.

Video
58 s at default settings: camera pans, a look up at the sky from the forest floor around 0:40, walking near Link's house.

Settings
Build defaults: no RX_* or HOS_* variables, nothing changed in the Insert menu, fresh shader cache (hookshot_programs.bin and *_pipelines.bin removed before the run). The recording was made with RX_VK_SHOTS, which only reads back finished frames.

What I tried

RX_VK_OOT_FOG lowered from 0.25 to 0.03: the sky comes back pale blue, but tree canopies become flat black against it. This suggests ambient/sky lighting is missing as well as the fog being too thick.
RX_VK_OOT_EXPOSURE 0.45: darker overall, shadows crushed, the sky stays white unless fog is lowered too.
RX_VK_ASTC_RGBA8=1 (no BC3 re-encode): no visible difference, so textures don't look like the cause.
Note: the RX_VK_OOT_* values are baked into hookshot_programs.bin, so changing them has no effect until the cache is cleared. Easy to trip over when testing.
The WebGPU back end (RX_BACKEND=webgpu) is even brighter, since it doesn't have the OoT visual workaround.

System

RTX 4070 Ti (driver 32.0.16.1664), Ryzen 7 5800X, 32 GB RAM
Windows 11 25H2 (build 26200)
Game 0400486024DEC000 v131072, built with the latest HookshotBuilder release
Performance is fine (about 50–60 FPS); this report is only about the visuals.
