Help/Support 📣 [HELP] COD Mobile ESP – Hooking CAMetalLayer or MTKView but nothing shows on

[Fricus 3 iPhone 15 Pro Max 18.4]

Hi everyone,

 

I’m currently working on an ESP mod for Call of Duty: Mobile (iOS).

It’s injected as a .dylib using Theos and tested both on jailbroken devices (Dopamine, iOS 15.6) and non-jailbroken (ESign-compatible).

 

 

 

 

✅ What’s working:

 

 

• I’m hooking -[UIViewController viewDidLayoutSubviews] using MSHookMessageEx
• I successfully locate the MTKView dynamically inside the view hierarchy
• The CAMetalLayer, nextDrawable, MTLCommandQueue, MTLCommandBuffer, and encoder are all valid
• I call DrawESP() using ImGui::GetBackgroundDrawList()->AddRect(...) with visible screen coordinates
• The code proceeds through ImGui::Render() and ImGui_ImplMetal_RenderDrawData(...)
• commandBuffer presentDrawable + commit runs with no errors
• ✅ Logs confirm everything is called and completed without crash

 

 

 

 

 

❌ The issue:

 

 

Nothing shows on screen. No ESP boxes, no ImGui UI, no crashes either.

Even though everything executes cleanly and logs indicate correct flow, nothing appears visually.

 

 

 

 

🔍 Already checked:

 

 

• The MTKView is properly attached to a visible UIViewController and active on screen
• The memory reads (EntityList, LocalPlayer, etc.) return valid data – confirmed from game dumps and offset analysis
• No UIView or UIKit overlay is interfering (this is pure Metal rendering using ImGui)
• Device is stable, and logs confirm correct Metal context

 

 

 

 

 

❓ What I need help with:

 

 

Has anyone here successfully displayed ImGui or ESP overlays inside COD Mobile iOS using a CAMetalLayer or MTKView?

Do I need to hook into a deeper rendering function, like RenderScene() inside CODM’s game engine, for it to actually draw to screen?

 

 

 

 

🧠 Setup:

 

 

• iPhone 11, iOS 15.6, Dopamine jailbreak
• Injection via Theos (no Logos, full ObjC++)
• Compatible with ESign for non-jailbreak testing
• Using imgui_impl_metal.mm backend (latest from GitHub)

 

 

 

 

Any help or suggestions would be greatly appreciated 🙏

If you have experience with ImGui rendering on CODM iOS, or know which engine-level method to hook, please share!

 

Thanks in advance!
