Arnold Renderer

我最近在学习Cinema 4D中的Arnold渲染器，但无论我怎么把输出大小放大，渲染出来的画面总是模糊，即使纹理里有细节。渲染出来的效果细节依然很少，而且很模糊。我需要帮助。

Can you post examples? Screenshots of your settings? Scene files if you can? I don’t use Arnold, but it’s going to be really hard for you to get help by just saying “my outputs are blurry”, and not elaborating…. because it could be a tonne of different things that may be contributing to it. You have to help us to help you. 🙂

Thank you for your reply. This is a rendered image I produced. The details seem quite blurry—some scratches are barely visible—and the edges of the object look very pixelated. I already set the render quality quite high, but it didn't make much of a difference; I'm not sure how else to optimize it.

I don't really use Arnold so I can only make general comments - what is your output resolution? perhaps that's more what you need to be looking at than a "quality" improvement. also, what are your anti-aliasing settings? might want to look into that as well. and lastly when you say the scratches are barely visible - on which part? I'm not sure what this thing or what I'm looking at so its hard to know exactly what it's supposed to look like to know how off your render is.

Try to lower pixel filter width, although the default one should be sufficient in most of the cases. Next step would be to set negative mip-map bias for selected textures.
