Object preview in asset browser

[schnekie]

Hi,

When I add object to the asset browser, I can’t see the thumbnail or generate it.

C4D R26.107, Corona 8 Hotfix 1, macOS 12.3.1

PS : With C4D R25 version everything works on the same computer

I could be wrong but I noticed that if you use Corona Bitmap on the texture slot the Preview doesn’t load in the browser. However without Corona Bitmap I do get previews.

Thank you for your help but I don’t use Corona Bitmap in this file

Same problem here.

Adding any object with a Corona Material to the Asset Browser results in a black preview image. It still works fine if loaded into a new scene … only the preview is buggy.
I’m working with R26.107 and Corona 8 (Hotfix 1).

The same procedure with R25.117 works just fine.

A similar bug happened with Material previews in the Material Manager when a Corona Bitmap node was used. But that got fixed with the Hotfix 1. I guess the next hotfix will get rid of that new bug too.

Hi,

The bug is still here in the latest daillybuild (Version • 10 (Daily Build Jan 23 2023)).

The model is the same in both objects. only the left one have Corona materials applied. So it seems indeed related to Corona. Can you fix it ?

We’re aware of this. The workaround is to do a quick render, copy it to the clipboard and then right-click on the asset and update preview from the clipboard.

Hi, is there any update or rough ETA for this feature?
Having to manually render or capture previews for every single object is pretty impractical in larger libraries.

A native automatic preview generation workflow (ideally with proper material/shader support) would make the Asset Browser much more usable in production. Other users seem to be running into the same limitation as well.

thank you
