2021 reflection probe blending in URP

Edit: Nevermind I can't read the docs. Too much work kills your brain. I wish I could delete this thread.

 

Don't think it supports blending yet.

Crazy timing! I'm prototyping a new project that I started just last weekend so I'll upgrade and give it a try right now.

For my particular use case I found a reflection probe se to realtime update every frame with time sliced as individual faces provided the effect I wanted though it had a performance hit. The nature of my game is such that just having a single probe updating near the player (which is a rigidbody hardsurface model so I wanted it to look reflective and shiny) was fine.

However I'll see if blending between baked probes that don't update is faster.

 

Is not working, I tested it out and is not working, the reflection snaps instantly when you enter or exit a reflection probe.Also the box projection is not working.

 

This doesn't appear to be the case in a19, I also don't see the new shader keywords in the Lit shader. Since the URP package version hasn't changed throughout the alpha I'm assuming no updated version is reeled in?

 

what's the perf hit compared to builtin?

 

I do not see anything , and is the latest alpha

 

Is it available to download?.

 

Could you run some now? there's been numerous regressions in the this version of unity and late catch is bad for us in production.
PS: love those colors on your icon

 

@nigeljw_unity Let me know where i can download that version!.

 

b1 is available, options are there now!

 

Still doesn't seem to be working despite activating the options in settings and the respective reflection probes, or is that just me?

EDIT: Never mind, it was a shader issue apparently

 

Damn, Thanks!.

Aparently is broken, xD the box projection works but the blending is not right, something is wrong with it. Is like it blends all the probes you have with the environment one.

 

is the probe blending really works in the latest released URP?


It is enabled on the settings but it seems it doesn't do anything


EDIT : Alright i think i finally starting to see the effect of it. and it seems the probe amount are very limited, like only 2 probe per object? even in deferred?

 

Yes, it's limited to 2 probes per objects in both rendering paths. I think this was also the case in the built-in RP?

 

if i'm not mistaken in built in, with forward we can only get 2 probes. But in built in deferred we can get more than that basically as much as you can in deferred reflection

Do you have this problem in the latest beta? https://forum.unity.com/threads/urp...ection-proble-blending-is-done-wrong.1132894/

 

Can you add Probe Rotation Support? It would be one more reason for people to choose URP over BIRP. moreover, HDRP also made this perfect. No need for a detailed interface like HDRP. It is a property that should be able to return the probe. I edited the URP and added it myself. I just rotate on Y axis and I use Indensity (unity_SpecCube0_HDR) for this, but because I only rotate Box projection, Probe Weight is not calculated correctly as in the last image.

 

Wow I expected in 2021, that URP would allow for a rotated box. It is just a matrix multiply after all which is very cheap.

 

wow in urp, this is perfect
how you can did that? ( I mean rotate box projection in URP )

 

Wow, it's been 3 years. It's a pity that we still don't get this feature in urp. I don't remember exactly how I did it.

https://docs.unity3d.com/Packages/com.unity.shadergraph@14.0/manual/Rotate-About-Axis-Node.html

I added the Unity_RotateAboutAxis_Radians_float function to the place where URP does the reflection probe box projection. I used intensity for the rotation data (I almost never use intensity). it worked. It only rotated on the Y axis, but that was enough.
