weird flickering bug on Unity 2018.1

Post by visionastral »

Hi there!
I just updated Unity to the 2018.1.0f2 version and now I'm having a weird flickering bug with AT2.
I'm on AT2 v 2.3.0.002, I have updated the shaders for 2018.1 and updated the virtual textures (but not rebuilt it, because it takes several hours)
There is severe flickering on the camera with AT2 that goes away as soon as I deactivate the AT manager or the AT script on the camera itself.
It's like the camera is being darkened a lot when a new mip level is loaded. Only the skybox, wich is in HDR, is visible on the highest brightness points.
This wasn't happening on Unity 2017.3

Here is a video of the issue:

Note the only textures amplified are the stone textures on the wall and on the floating cube.
The floor is NOT amplified.
Notice how the flickering increases as the floating cube approaches the camera.

Well, at least is not my fault and it's a known issue! :D
It's a hard bug to fix? Because I still can go back to Unity 2017 right now.
I was upgrading to 2018 for the IL2CPP backend and the new multi-threading features, but AT2 is much much more important for me!

It's a tricky one, it's flickering whenever uploading pages but it should be possible to fix. I would recommend not updating for now, we'll keep you posted on any related developments.

Thanks!

Cool, going back to Unity 2017 then.
I'll check with 2017.4 LTS, since it should be like 2017.3

Hello
After migrating to Unity 2018.1 I have the same issue. But I notice flickering is only on linear color space, on gamma color space amplify is working correctly.

Any update on this patch?

Were trying to switch to unity 2018.2 but are suffering the same problem.

IS there a temporary workaround i can apply?
