Hi Gurus, I am having problem with my content browser thumnail. As soon as I import anything new to my package my asset thumnails stays pitch black. I have tried to set up custom thumbnail, no luck. Any idea?

Any update on this? I get the issue as well. It’s happening when I duplicate a blueprint. Restarting the engine fixes it for me though.

I get a black thumbnail when I duplicate a blueprint (in 4.16) having a few child components (lights, static mesh).

I just thought I’d share the tip that selecting Asset Actions → Reload works a little easier than restarting the whole editor.

I’d prefer a fix though!

Bump! The problem persists.

Furthermore, some of the assets, like Static Meshes turned black precisely when I activated Nanite on them and tweaked the Trim Relative Error value.

Does anyone have an idea how to fix it?
