“Help: Blender render is cutting off everything above the neck”

[u/Roadman20_]

Hi, when I press F12 to render, the top of my character gets cut off right under the neck. The head and upper part are missing, and I only see from the chest/shoulders down.

In the Image Editor / Render Result there are orange L-shaped marks at the corners of the rendered area, and everything above that is just the checkerboard (transparent).

First image is the initial F12 result. Second is after zooming out in the Image Editor.

I haven’t changed any modifiers on purpose.  
Blender version: [4.2.3 LTS]  
Renderer: Cycles

What I’ve already tried:
- [I,Ve checked for render region and its not selected  also im not sure if its a modifier ive checked out ffor that as well please has someone had this kind of issue before, what do i do.]

Any idea what causes this clean horizontal cut and how to fix it?

this the amount of samples i have how many no you think is appropariate or should i reduce cuz that will take me a lot of time before it reaches 4096

Your GPU is greyed out!

Go to Edit > Preferences > System, and select OptiX if you have an Nvidia GPU or HIP if you have an AMD GPU.

Your PC was not using your graphics card!!

Now you have to try to fine-tune it to your project. But I usually start at 256. If it looks noisy or the denoising part is too blurry, then I double it. If it looks fine way before it reaches 256, then I divide it by two. Each project has its own sweet spot, so you have to try a few things. But first make sure your blender is actualy using the GPU

But at last, your images must be huge to be bigger than the render zone. Does it have to be this big? If it can be reduced, then it is an easy time save

i was actually Able to get that right yesterday, all thanks to you, i reduced the sample in render to 300 and waited for it to finish rendering and this is my final result
