In this cartoon, everything is made of modeling clay. Something new happens in every episode. Most of the surrounding space is empty; there is only the main character and the objects the character interacts with. The objects appear out of nowhere or change shape.

Edit 1: Maybe there is no main character

In this sci-fi movie, for some reason(I don't remember) a person ends up outside the building. The sun there is so hot that it can kill. So the person either starts burning, or gets rescued before the extreme heat fully sets in — I do not remember exactly.

Not sure about:

Outside the building, there is sand.

It is another planet.

Metal automated shutters protect against the sun at peak hours, and the scene is happening during peak solar activity.
