# 4K、HD等所谓的Rendering词有用吗？

这里包含以下词：

`4k, 6k, 8k, 16k, ultra 4k, octane, unreal, v-ray, lumion, renderman, hd, hdr, hdmi, high-resolution, dp, dpi, ppi, 1080p`

> **官方说明：**
>
> Rendering words do something to your image. They may also be what's breaking your prompt. So, as part of troubleshooting, we recommend removing them. Removing them often fixes issues with blurring, focus, clarity, and coherence.

大概意思是会影响，有一定作用，但弊大于利。加入这些词，反而会破坏你的 prompt，特别是一些摄影场景，比如你需要用到诸如背景虚化等效果，再加上 4K 可能就会破坏背景虚化。

**所以官方是建议去掉这些词。**
