I can't see any geometry when I load the entry.udsa file for Animal Logic's Alab demo.

I downloaded the files, created a sublayer LOP, and set my scene frame range to start at 1004. The scene is visible in the Solaris scene graph outliner, but I get nothing in the viewport and the camera01 listed in the outliner is not available as a viewable camera.

What am I missing?

Did you download all the files textures, camera, geo, etc...?

I just downloaded all the assets. I first unzipped "Asset Structure".. that set the folder structure for the project.

Then I downloaded all the others, unzipping and putting them in each respective folder. See screenshot. The text on the website as tells you how to unzip and copy of the stuff.
