ControlNet masks are always blank and have no effect on the final image

Not sure what the issue is. Using a runpod instance with RTX A5000 29GB ram

Non-zero canvas + external image will result in the issue. Ensure that the canvas is empty if you want to upload image as input.

So the canvas is completely empty. I've tried clicking to upload the image as well as copy pasting the image to canvas. Neither actually work...

Having the same issue, using 1.5 SD model with fresh instance of Automatic1111.

Couldn't reproduce. Maybe something like browser compatibility?

[ezynda3]

Ok weird but it seems like it doesn't work in Brave browser but does in Chrome...

[andr8337]

I use firefox, and it works on chrome. Appears to be the extension "CanvasBlocker" used to avoid fingerprinting, it has to be completely disabled and not just turned off.

Interesting. Does CanvasBlocker allow whitelisting certain domains so it will not act on them? Depending on the implementation, that might not be enough, but I'm just curious. A quick look around, I'm having trouble figuring out if that's possible.

[andr8337]

In my short testing it seems to need total disabling in settings, not just turned off. So a whitelist properly won't be enough.

Yeah, can't load it while using brave browser

Fwiw, for me it doesn't work on Chrome either, but your suggestion that it's due to extensions made me try it in the incognito mode, where it works fine. In my case, the extension that caused it to fail was Crumbs.

I am having the same issue, that it generates white empty mask, but only with MSLD preprocessor, canny and others work as expected. Anyone experiencing same issue?

So, I've been fighting this issue all last week and I've came to the conclusion that it does not work unless accessing from localhost or 127.0.0.1. Any domain names or even the Gradio proxy url will cause it to fail.

I am using Brave and was able to fix the issue by putting the Shields Down/Trusting my domain url. Appears to be related to some of the tracker blocking, so it will likely be related to any other Ad blocking features in browsers or extensions.
