After migrate from 4.21 to 4.25 specular changes a lot when camera moves

Development Programming & Scripting

Hello,

We are migrated our project from 4.21 to 4.25 and we detected that the specular changes a lot when camera moves.

Attached two images as examples:

Image1
Image2

In 4.21 the problem in image 2 does not exist.

Image4.21

Thanks for your help

I link the images.
In game and build happens the same.

I noticed this, not many others, apparently.

But it doesn’t happen in game, right?

PS: You didn’t attach any images.

That actually looks like a change in roughness.

Thanks for the help.I thought it was a Specular thing, because specular depends on the angle of the camera and the incidence of light and the problem is that it changes when you change the camera. So I thought it was a problem of specular, rather than roughness.
The thing is that everything was working fine on 4.21.

Have you tried tweaking the settings to see what is actually going on?

SOLVED: I found the solutions when search by roughness flickering. The problem was the Temporal AA was not active, I activated it and the problem was solved.
