Adding textures to usd file

Hi,
I am having a usd file in omniverse create, but the texture is missing.
How is it possible, to attach the .png texture to a existing .usd file in omniverse create?

I think what you want to do is right click your prop, Select Create - Material - Omni PBR

Then find the Omni PBR in the Looks section of the stage, and set the Albedo Map

You can also set the brightness here with Albedo Brightness.

You might have to adjust the Scale of the Texture using the Texture UV Scale.
