[PD] Writing texture to different sides of cube in GEM

[Adityo Pratomo]

Hi there everyone, i have a question here. How can i write different
images on every different sides of a cube in GEM? So that when i
rotate a cube, i could see a certain image on a certain side. I know i
should use [pix_image] and [pix_texture] but how can i achieve my
goal? I kinda lost here. Many thanks for any suggestions. :-)
