SSAO seems to be inverted in my scene?

[HybridFox]

So i am kind of out of ideas for what this issue could be. But i am trying to simply implement SSAO in my three fiber scene. Using these settings (and with blendFunction NORMAL) I am able to get this showing:

But the SSAO seems to be inverted and incorrect, if anyone has an idea what i am doing wrong or with what settings i could fix this, i will be eternally grateful!

yep, noticed it, too, postprocessing changed how ssao works it seems. i tried to look up what's going on but it seems to go through a major refactor and it's not so easy to figure out what the steps we would have to take are. pmndrs/postprocessing#279

Did this work with previous versions of postprocessing? Minor or patch versions are not supposed to introduce breaking changes; if they do then that's a bug. I'll investigate.

hello @vanruesc yes, this came with an npm update, not a patch, a minor feature update.

-    "postprocessing": "^6.23.3",
+    "postprocessing": "^6.24.0",

Is there any existing SSAO sandbox I could play around with?

I ran into the same thing yesterday. Here's a broken version.

And an older working version

I tracked down the issue to this line:

react-postprocessing/src/EffectComposer.tsx

Line 79 in e9bfdef

if (normalPass) normalPass.enabled = false

which was changed in 97cd9b6. The NormalPass never gets re-enabled and thus never runs.

oh my, what a typo :-S that fixed it! thanks a bunch @vanruesc

[HybridFox]

Indeed, v2.1.5 fixes it! Thank you so much for the quick action!

I'm on @react-three/postprocessing 2.1.6 + postprocessing 6.25.0 it seems I have this problem.

I've updated all the libs to the latest, it's ok!
