Negative prompt weight？

[xyxxmb]

When I trying the weighted prompt, I find that the positive weight works and perfers better, but the negative works worse.

Is there a way to make certain descriptions not appear in the image by specifying negative weights? For example the watermark, signature:-1？

This seems to work: "positive prompts ### negative prompts" (So ### is the denominator, everything after that is a negative prompt) https://github.com/sd-webui/stable-diffusion-webui/pull/1035

Or as stated in that pull, leave a space inbetween ":-1" and the prompt, so "signature :-1" to weigh the prompts https://github.com/sd-webui/stable-diffusion-webui/discussions/525
