Screen created using cylinder to create base
Create plane and place
(plane will ab animated layer
Select projector placement (hanging off beam)
Create cylinder + box underneath
alt + q = isolation mode
Apply chamfer to depth edges
Apply connect down depth - high number - even
Select every other polygon along chamfer edges - extrude into object
Select front side - inset
Drag inset geometry away from object to create slope
Duplicate cylinder
Rotate and place as shown - apply inset + extrude inwards
Group (if necessary)
Exit isolation mode and adjust position if necessary
Projector requires light source to project onto screen
First applied material to projector (as should've been done before)
Lights - standard - mr target light (mental ray target light) Put source in centre of projector cylinder
Place target in centre of screen
Changed light cone to rectangle from circle
Rendering - environment - add volume light - begin adjusting settings
Lighting - select light (select projector light)
Render to test - defualt settings is full uniform solid light amount
Add noise filter to create more uneven light
Reduce density so barley visible as reqiured
Adjust size of volume light slightly (decrease target size) to fit screen better
Created material in photoshop consists of 6 pictures stacked
vertically and big gap of black to slide to when "turning off" projector
Apply bitmap to material - collapsed
Apply to projector screen - uvw map - box
Rescale to fit single slide - rendered to check bitmap quality (low quality only in viewport)
Use auto key to increase (or decrease) bitmap position vertically to effectively change slide shown on screen
Used formula of 6 frames per interchange - leave each slide on for 50 frames - repeat
When animation shows projector being turned off - slide bitmap texture to black part to represent turn off
