A [Cubemap] without image data. This class replaces a [Cubemap] or a [Cubemap]-derived class in 2 conditions: - In dedicated server mode, where the image data shouldn't affect game logic. This allows reducing the exported PCK's size significantly. - When the [Cubemap]-derived class is missing, for example when using a different engine version. [b]Note:[/b] This class is not intended for rendering or for use in shaders. Operations like calculating UV are not guaranteed to work.
