Bug Asset Thumbnails Blank. "Texture creation failed. 'None' is not supported for Render usage"

I am using Unity verson 2022.1.1f1 with URP. None of my meshes, prefabs or materials show thumbnails. I have tried to refresh and reimport them with no success.





I can edit a value in a material and the thumbnail will show until I save my project again, then it will return to being blank.

I am getting an error that seems to occur somewhat randomly. Sometimes at runtime, sometimes when I save.

Any help would be appreciated, thanks!

 

I could really use a response from Unity on this. The error in question is not just happening with TireMarks.mat, but with all materials and meshes. It is making working on my project much more difficult than it should be.

 

I have exactly the same problem with the same exceptions being thrown.
The problem appeared for me since upgrading a project from an older version.

UnityEditor.AssetPreviewUpdater:CreatePreviewForAsset(Object, Object[], String)

Suggests that texture creation fails, but the result seems to get cached either way and that is why the preview appears empty would be my guess.

EDIT: managed to fix it by creating a new urp asset and selecting it in project settings.
EDIT 2: sadly this solution also stopped working after some hours.

 

Same problem for me (2022.1.3), unfortunately after a day of testing, I couldn't find any fix.
This problem should be a priority, if you work on the materials it is unusable.

 

This also occurred for me once I upgraded my project from an older version.

Still no word from Unity... could we please get some support on this issue?

 

I found a solution, I recreated the 3 files for the URP and I re-assigned them in "Project setting".



Then after the first save of the scene, the Thumbnails reappeared.

Hope it still works tomorrow...

 

Edit :
after restarting unity it still works, but:

- I still have the error msgs.
- Only Shader Graph materials are displayed correctly, custom shader or standard URP do not work.​

 

I'm still experiencing this problem.
Has anyone found a solution?

 

I found the ticket, and it's closed, and says fixed, but clearly not.. URP 13.1.8 now, still not working.

have this issue both on latest 2021 and 2022 beta,,

 

I get the same error message. I am currently developing a EditorTool and need the "AssetPreview.GetAssetPreview()"-Preview of the objects, but it allways return a blank preview.

What helped for me was marking the asset as dirty.

EditorUtility.SetDirty( gameobject);

Then the asset preview reappear. Idk why this is happening.

I use URP and ShaderGraph-Shaders.

 

Where would I put it? I have only a very rudimentary understanding of editor programming.

 

I got mine working again, by changing rendering path to deferred also changing the masks.
Which is terrible, because this should only effect the project NOT THE EDITOR.

Anyway, changed to deferred and random clicked around the layers then it started loading and show the prefabs again.,
However ALL the warnings and alarms are still shown..

But now at least i can work

 

I think I found what's causing this bug.
It looks like the Opaque Texture setting in the default URP asset is the culprit. It's not fixed in the recent stable release (I'm using 2022.1.10f1, URP 13.1.8).
My guess is that probably these settings are used for thumbnail generation camera and the texture is not properly init there.

For now, I've disabled the Opaque Texture in the URP asset and enabled it in the main camera's rendering override setting instead. The only drawback I can see is that now, the scene camera doesn't have the texture, but I can live with that.

 

Thanks Herbal, certainly, only projects with Opaque Texture enabled are those with blank thumbnails. After changing the setting, the thumbnails comes back.

 

Same problem on latest unity 2022.1.12f1...

 

Been having this same problem.

 

I have developed a transparent shader (using the shader graph) that does funky things with the light as it passes through the mesh. I found that I have to turn on OpaqueTextures in the URP-HighFidelity to get my shader to render transparent.

I am currently using 2022.1.14f1. I don't recall this problem with 2021.1.24f1, but I may not have noticed. I am not certain the impact it has on the game I am developing. I am thinking of moving back to the recommended LTS 2021.3.8f.

If I can turn on the transparency without turning on the OpaqueTextures flag that might be the best solution to move forward with this latest version. Any insight is appreciated.

EDIT 9/22/22- I am not sure why but I don't see the error message any longer. I turned on opaque textures for all three qualities of URP settings. But now if I turn them all off and on again, I still don't get the error messages. I don't recall if I did something else to trigger the issue. If I see it again and determine what I was doing to trigger it I will update this post.

 

This issue still persists when running the latest non-alpha/beta build available in 2022.1.16f1. Unfortunately due to using custom render features that require OpaqueTextures to be checked the workaround is wont cut it and rolling back to 2012LTS, 2020LTS, or even 2019LTS leave too many unfinished features and issues that forced me to update in the first place.

This bug has also occurred for me for months. It is by it's very nature hard to reproduce, but disabling Opaque Texture seems to have stopped the error from occurring.

 

We're encountering this error message after updating our project to 2022.1.16f1, and can confirm that changing the Surface Type on a material from Opaque to Transparent removes the error and correctly generates the thumbnail. However given that we're specifically using the Opaque surface type this isn't a valid solution. Is there any update on a fix for this?

 

After at least 4 Unity updates it seems to me really absurd that there is still this problem. No fixes even in the last 2022.1.17f1. Unity are we going to wake up or not?

 

To update everyone... I was unable to resolve this issue in any proper way. I ended up exporting most of my project as a package and importing it into a totally new Unity project with the latest LTS.

I know that isn't what people want to hear... Fortunately my project was still small enough where this only took a day of work, but I can imagine that isn't a workable solution for others.

 

Yep. I got the same bug as y'all. It looks like it's the Opaque Texture. I disabled it in all my URP assets, restarted Unity, and thumbnails are back. URP 13.1.8 v2022.1.20f1

There is some good news though. Looks like our issue is in review for one of the next versions... https://issuetracker.unity3d.com/is...lit-shader-graph-if-opaque-texture-is-enabled

It remains to be seen if it will actually stay fixed though, lol

 

for future googlers: delete library folder and restart editor

 

2021.2.0b11 and if I disable opaque texture in the URP asset, refresh or even reimport, thumbnails still don't appear ¬¬

This, and the fact that shader graph's preview isn't worlking too (not in my beta, but even in 2021 LTS releases I've tried) is driving me absolutely nuts.

Starting to think about migrating my game to a 2023 release...wich is going to take me months.

PD: tried to delete library folder too, just in case. Rebuilt it and doesn't work.
