Adding wrap-around screen to 3D render
on Jun 27, 2018 at 6:10:30 pm

Hi folks,
I'm trying to find the easiest way to get a piece of footage to wrap around a 3D render of a TV screen. See attached



See that little corner bend? What's the easiest way to accomplish this?

Make two precomps: one for the square piece, one for the corner piece, both fed by the full-width source image. Use CC Power Pin to put each precomp in its respective place over the render, and use track mattes to handle any places where the image should be obscured (like the bend of the column on the left).

Cool, but that's already what I sorta did with the corner pin tool. The issue is I want the two pre-comps for the square screen and the corner screen to look like one piece of footage.

I guess I don't understand what you mean by "look like one piece of footage." Are you trying to show a projection effect where it looks like the screen doesn't bend at that corner?

No, I'm trying to make it look like one big screen with a bend - have the footage wrap around the screen, like this iphone -





Sorry this is a bit confusing - thanks for the patiences. :)

[Dave LaRonde] "You can. Figure it out."

Agreed.
You are so close.
You just need to make sure the two comps anchor points are at the seam.

Okay, so using 2 precomps wasn't working. What I did was make one precomp, used corner pin to pin each corner across all the screens, then used mesh warp and a bit of shadow and trkmat action to give it that wrap around look.

Thank you so much, Walter & Eric. Dave, sorry I came to a support forum for support? Was a little shocked to see such a response from an admin... but I did end up figuring it out, so thumbs-up?
