Tracking of progress for entry for this colab will happen here:
Restrictions:
*low poly
*no textures
My goal is to have 2 simple low-poly dioramas to represent a child’s imagination. I will be reusing the low-poly orc models made as a side to the character course, and will be creating the dioramas, the child, the star-trooper and the trees.
Quick concept sketch:
The scenes should transition between each other as the camera moves past the window-plane in almost a “Stranger Things” fashion. To achieve this effect I would need to know the camera position in the scene… Took all of Sunday to figure that out:
That’s it - that’s how you calculate the camera position, just transform (0,0,0) from camera space to world space. Obvious once you figure it out, but did it take some time figuring out! 
Anyway, you just seperate out the y coordinate and you can drive alpha of the shaders off of that. If the window is in the y=0 plane, the effect should be convincing…We’ll see how it works out.
