I'm creating my own Solaris Layout (USD) Assets for our current production.
However, when I try to add my USD asset to the Layout Asset Gallery, the thumbnail is too dark.
I tried to create my own manual thumbnail that's correctly lit, but when I add the asset to the library, Houdini auto-regenerates the thumbnail! Making it too dark again.

What am I missing?

Is there a way to prevent the Gallery from auto-generating the thumbnail?
I'm using the Component Output LOP with Source set to Input Primitives.

Running Houdini 20.0.625 - Py3.10 on Ubuntu.

Thanks
