On the Panda 1.8.1 I got a red teapot, and i’s a right result as far as I can see. Which version do you use?

I use the panda1.9,and instead of cg is ok.

Panda3D 1.9 has not been released yet. There’s no way for us to know which version you are really using. Did you use the daily build, and if so, do you remember its date?

I don’t know it’s date.I would reinstall 1.81.
