I’m trying to add a reflection probe that uses a custom cubemap. Using a new HDRP project and Unity 2022.1.15, when I add a custom reflection probe to the scene, all mirrored surfaces turn black:
You can see the cubemap texture is set, but it’s not being used.
In comparison, if I switch to realtime, reflections show up:
This seems like a regression but I’m not sure when it would’ve been introduced.
Does anyone have custom reflection probes that work?
Is your cubemap in HDR format? How is it being created?
It might be just too dark to begin with.
Keep in mind that the usual sun intensity is about 120k+ lux, so you need to take that into account when generating your HDR cubemap, or simply lower the directional light intensity (a lot) until you see the reflections appear again.
Thanks for following up! I tried two things:
All of them create the same pitch black reflection probe.
I also tried changing the .exr file’s f-stops to bump exposure up, but that didn’t do anything. Dropping directional light intensity didn’t help either.
I’m not sure what else I could try? The reflection probe texture selector only accepts cubemap textures, and not skybox materials, so I don’t think I have a lot of control over brightness.
I think the reflection probe also has an intensity multiplier, maybe try that first as well.
Oh wow, yes, that was exactly the problem!
Here’s the magical setting for anyone who’s searching for this solution in the future:
Thank you both @SebLazyWizard and @Win3xploder !
