SlotMachineRenderTextureFix

Fixes the Reel of Fortune slot machine display not rendering in How to Fish on high resolutions (>1858px screen height), on both Linux/Proton and Windows.

Cause

GameInfo.Awake() sizes the slot machine's RenderTexture as:

int value = (int)(Screen.height * 0.25f);      // clamped to 1440
int num   = (int)(value * 4.40625f);
_slotMachineTexture.width  = num * 8;          // up to 19032 px
_slotMachineTexture.height = value * 8;

At screen heights above ~1858px this exceeds the GPU hard limit (SystemInfo.maxTextureSize, typically 16384). RenderTexture.Create then fails silently every frame — you'll see this spamming the Unity log:

RenderTexture.Create failed: requested size (19032, 4320) is too large for the current maxRenderTextureSize(16384).
RenderPass: Unable to find surface for attachment 0
EndRenderPass: Not inside a Renderpass

The secondary camera that draws the reels (SlotMachine._slotCam.Render()) writes into a dead render target, so the display stays black / missing.

Fix

Harmony postfix on GameInfo.Awake clamps _slotMachineTexture proportionally to SystemInfo.maxTextureSize and re-creates it before the camera renders into it. Works at any resolution; no config.

Example at 4K: 19032×4320 → 16384×3720.

Install

Requires BepInExPack for How to Fish.

Drop SlotMachineFix.dll into BepInEx/plugins/.

Verify

After launch, check BepInEx/LogOutput.log:

[Info   :SlotMachineFix] SlotMachineFix loaded
[Warning:SlotMachineFix] Clamped slot RT 19032x4320 -> 16384x3720 (max 16384) Create=True

No more RenderTexture.Create failed spam in Player.log.
