Hello guys. How can I use expressions to assign the names without dragging from the scene graph path? Thanks

Have a read of this:

Thanks for the page. I couldn't find any info related to what I need.

Thanks for the page. I couldn't find any info related to what I need.

That page does show you how to use expressions to get prim names instead of dragging them from the Scene Graph Tree, which is what your original post describes.

So, if that page isn't helping, can you describe specifically what you want to achieve?

You could use wild cards * with the build01Afacade, build02Efacade, build03Afacade geometries.

The primitive path would be something like "/geo/steps199/_199steps_cam0_assets/build0**facade". This would allow you to capture buildings 1-9 and any alphabet character in place of the wild cards. The same could be done for reflect and fence, assuming you want the same material applied.
