Hard getting good results with reflection probes

Here is the pre condition, objects in shadow under a train underpass

Here probe with default settings. The objects pop out unnatural

Here I have tried to make it more natural by removing sky and stuff in the sun. Now it pops the other way, completely black. :smile:

Lowering intensity doesn’t look good either

Any more ideas?

Hey AndersMalmgren, have you tried to place the probe at your objects location to be sure it is not a reprojection problem. If it is not you might then want to check your material definition Unity - Manual: Material charts

Hi, this probe is 4x3 meters are you saying we need even higher density? I can try to move the probe so it’s right above the objects you see in the screenshot.

The density is not the problem here imho. At a glance i would say that the material is too reflective or it reflect as from an unrelated position rather. Let us know your findings. If this is the latter Unity - Manual: Post-processing and full-screen effects might help there if it is an option for your project.

If you want to achieve better results with reflection probes, I would suggest nesting them under one another. What I mean by this, is:

  • Place a global reflection probe, which encompasses a large portion of the environment

  • Place a secondary probe within the global one, which encompasses a room, or a portion of the environment

  • Place a tertiary probe within the secondary one, which encompasses smaller reflective objects

This should give you a much more convincing result. Keep in mind that the solution might not be perfect still. In that case, I would recommend employing screen space reflections using our own Post Processing Stack.

Yeah, thats what I’m doing, in this case I use importance 2 becasuse the global one is so different from this one since its in shadow so I dont want anything bleed over from it.

Screen space reflection isnt an option in VR though sadly. Plus isnt it best suited for planar reflections?

Will play around some more. But its very hard getting good results. More so in VR since even the smallest of reflection will be noticeable at the large scale of VR.

As I mentioned in my previous comment, you need a more granular approach to reflection probes. Judging from your screenshot, you only have two nesting probes. Place one smaller probe which only encompasses the trash bags and the tires, and set it to higher importance.

Ah ok. will try.

It actually becomes a little better if I place a probe close to the trash. Still its a bit outlined but alot less of that yellow tint in the outline

Try enabling box projection on that probe. It should help a bit in your case.

Thanks it made it look slightly better from some angels but worse from others.
