Architectural / Blueprint
Hello,
I’m wanting to create a background of lines being drawn that look like car blueprints. However, I don’t have any blueprints to work with, nor can I draw!
I have zero ability when it comes to expressions. I was just wondering if there is an expression/setup I can use, to random animate ‘blueprint’ looking lines slowly revealing?
It’s only for movement in the background and will be about 50% opacity. It’s an 8 minute video, so randomness is key.
Any suggestions would be helpful!
Thanks.

I’d create some Shape layers with multiple straight lines, then add a stroke.
You can add dotted line strokes which is also nice for a blueprint looks,
Then add path offset, you can then animate the strokes very easily using start/end/offset.
No expressions needed, just check the manual for shapes.And don’t rely on expressions to do everything magically for you, sometimes you do need to work to get results…

Henry,
You could actualy can do this using an expression, and the “CC Time Blend” effect…1. Create a new composition, create a Solid in it, and make a small
round mask on that solid (i.e.: small circle on a transparent background). Make the size of the circle as your desired Blueprint line width .
2. give that solid a wiggle position expression, something like:
wiggle(0.1,300)
so you will have this small circle moving on a random path.
3. Insert this composition to your main comp,
and give it the “CC Time Blend” effect, with Transfer = Add, Accumulation = 100%And that’s it !
Play with the wiggle paramethers to achieve a different stroke path.
p.s.: The “CC Time Blend” effect needs to be rendered always from the beginning of the timeline, so always before you make a RAM preview, clean the cache by Edit -> Purge -> All. (or else you could get strange results in the RAM preview)
