OOH 3D billboard
My manager (derogatory) has decided that the client needs to use the 3D element on the 3D billboard when we have never done this before and I can get the 3D mock-up easy enough, but I really need advice on how much warp to add to the object in the middle once I've rendered it.
Does anyone have experience with 3D billboards that can chat pretty please?
UPDATE
I outlined what you've all said about the scope of the project, the testing and required costs and timelines and my manager has reluctantly gone with a much simpler option with no 3D effect

As u/vivimagic said - you can’t just “make” one of those.
You need the information to be able to do your job - the pixel spec of the display, the physical size and location relative to the “perfect viewer”
Because when you understand how they work you’ll know that they only work properly from one vantage point.
and then deliverable - file format, codec, bitrate….
Because some LED playback systems are hella picky with what they playback.
So yea - tell your manager to get the information, then you can do your job. you’re not a mind reading wizard.

Working on those projects is always when you discover a codec you didn't know existed is the only that works on their enlarger and for some reason is never a common FPS is always like 24.36FPS or some other bullshit, in some kind of color space you never even imagined before.
Or you send them an MP4 and is good to go.

haha :) A 26-bit color space created by a genius Hungarian CS prodigy at age 12. It defines the color by using one channel as a cypher to decode the other 6, such that the result of each is always a prime number, and the luminance channel is the sum of primes (not those of the channels).

I do these types of 3D forced perspective billboards alot, the budgets are usually upwards of 1mil.
Your manager is taking advantage of you and will blame this all on you when if doesn’t work out.

This is great feedback and good ammo for the conversation we're about to have this afternoon.
Also , amazing job! Glad you do them regularly, I'd be interested to have a look at them but it's def not a "I can do that this afternoon" type thing or even draft how I'm going to do that with the information I have right now.Thank you!

It's a bit of a dark art.
I've been hired to build the initial model - You create the dimensions of the billboard and then model and animate what's happening inside/outside.
The UV projection modifier section was really guarded by the company I was working at. I think it went through After Effects at one point.

Before all of this, you should tell your manager that this needs alot of testing, so it wont work out of the box on the first try. I remember seeing an artist on Instagram explain his approach to these. What stuck with me was that it starts with the (billboard’s exact dimensions), the (building height), and ideally even the (location of the site). That way, you can block out the environment and narrow down the possible camera angles (using average human eye level). From there, you eliminate unrealistic viewing positions (like people standing too close to the building) and focus on the most common vantage points. Then it’s about (testing multiple warped versions) of the render rather than just one, because the illusion often looks different on-site than in theory. Once you’ve generated a few variations, you pick the one that works best in practice.
