I used Unity 2019.1.0f2, and then I updated Unity to 2019.1.9f1 and I still have main preview window blank, how do I fix this?
Maybe you’re zoomed inside of the preview object? Have you tried changing the preview primitive?
Also, you’re utilizing alpha, are you sure, you’re not just setting everything to invisible?
No, it is not zoomed. Yes, I have tried changing the preview primitive. Even new graph’s preview window is blank. But in the end I created some shader in HDRP menu and its window is okay. But PBR Graphs window is still blank, but it works fine.
What version of Shader Graph are you using?
Shader Graph 5.7.2 and Unity 2019.1.9f1
Yeap, checked on the same versions, can confirm — no preview for PBR Graph (tested in HDRP).
Same with 2019.2.2f1 LWRP PBR shader. (Windows 10)
Same on 2020.1.2f1 using Sprite Unlit Graph on Windows 10.
On MacOs it works
I have the same problem. Have you solved it?
Delete the old universal render pipeline asset and render, and then re import the LRP and shadergraph packages.
