You are given a set of semi-transparent and half-opaque tiles Place those tiles one on top of another, so when overlapped,they form target image.
Individual tiles - Ex1 to switch, Ex2 to rotate.
Main spot - Ex1 to place & combine tiles in order. If you get target image, secrets pop open.

1. Set up a sequence of combos using the same tile sizes for transparent tiles.
2. mport and compile the script. 2 FFCs used.
3.ffc script RenderPriorityPuzzle
Place FFC at position, where the picture should be assembled.
D0-D5 = puzzle solution
#####.___ combo of image.
_____.#### rotation, multipled by 90 degrees.
D6 - X size, negative for translucency.
D7 - Y size, negative to just render target image, not accept solution

4. ffc script RenderPriorityInputer
Place multiple FFCs to form individual tiles that are swapped and rotated prior to combing.
D0 - number of combos in sequence.
D1 - order of tile placement, must be unique per FFC from range 0-5.
D2 - 0 -> disable rotating.
D3 - translucent, if >0.

A note on designing puzzles, make sure that target image can only be builat with unique, order of tile overlappings, no ambiguity is allowed.
