I don’t know if that’s what you call them, but I need to create a cube to serve as the sky. How would I put the texture on the inside of the cube?
In blender, you can recalculate normals inside using Shift+Ctrl+N on any set of faces. Make your box, apply the textures to the outside of the box, and then flip the normals inside.
I don’t know if there is a way to do this in panda3d.
A link to make skybox in blender.
Or you can just find an existing skybox, replace the files reference in the egg file, then you can get a skybox immediately.
Or use a cube map.
