blender eevee / cycle 렌더 헤드리스

노트북에서는 오히려 학습 데이터 생성이 빠른데

데스크탑에서 느려서 확인해보니

 

노트북에서는 이렇게 nvtop 돌리니까 gpu를 사용한다.

 

아무튼.. claude 말로는 cycles 돌리면 빨라진다는데 흐음.. cycles는 raytracing쪽 설정때문에 잘 모르겠던데..

 

eevee는 gpu 렌더러라 gpu가 없으면 작동안한다고. 그런데 왜.. headless 구성에 영향을 받지?

EEVEE is a GPU renderer. You cannot use it without a GPU. It can only use GPU to render, doesn't even support CPU rendering. This means it uses whatever week GPU you have and, sure it can run out of memory and stop being able to cope very quickly.  – Martynas Žiemys  CommentedDec 15, 2024 at 16:42

CPU Rendering Being a rasterization engine, EEVEE only uses the power of the GPU to render. There is no plan to support CPU (software) rendering as it would be very inefficient. CPU power is still needed to handle high scene complexity as the geometry must be prepared by the CPU before rendering each frame.

아무튼 bpy 에서는 아래처럼 cycles를 설정하면 헤드리스 설정이라도 gpu 가속 잘 받는다고

scene = bpy.context.scene scene.render.engine = "CYCLES" scene.cycles.device = "GPU" scene.cycles.samples = CYCLES_SAMPLES scene.cycles.use_denoising = CYCLES_USE_DENOISING
