This problem occurs when in the scene editor I add by hand from the node list a World Environment, make an Environment, make a Cubemap. When I press play, in a script the Worldenvironment is added as a child to a Spatial which is my main node, which was somewhat of an arbitrary choice when I began my project. <br><br>The WorldEnvironment is detected with a print statement, but does not appear, so I open the scene from the directory to see what's up.<br><br>All but the first cubemap image are not saved in the list of 'Top, Bottom, Left, Right, Front, Back' images. I have added them many times and each time I open the scene, they are all set to 'Empty'. Even when I save each resource and teh scene individually with save or save as. Extremely frustrating.
