Help Me Please!

where do i put the models i downloaded and get them to load wiht the script?

You can put them in your working folder or just simply copy them to the [Panda3D installation]/models/. Panda will search for models firstly in the same folder as the script file, if the models aren’t there, then Panda will search for it in the [Panda3D installation]/models/.

Please read this or the manual
