Work flow to apply light wrap and edge blur in a 3d scene?

PostSun Apr 16, 2017 7:04 pm

Hello everyone,

I'm hoping you may have some suggestions on how to handle this..

I am working with 3d scenes built in fusion that incorporate green screen footage that are attached to planes in order to position them within the scene.

I would still like to be able to apply light wrap and edge blur to help tie the footage into the environment (usually I'm using TheWrapper macro).. in a 2d scene this is done obviously enough but I'm having trouble coming up with a useable workflow in 3d..

The obvious workaround that came to mind was to run the background through a 3d renderer and then use that input for the background of TheWrapper, after which pump the wrapped output onto the image plane which then combines into the scene via another 3d merge followed by another renderer.

Now there are two issues doing it this way.. the most obvious is that I'm getting the combined image of background and foreground on my image plane which doesn't help.. secondly is sizing and positioning, the image on the plane (along with its lightwrap) is obviously not going to line up with the sized and repositioned object in the final 3d scene.. and by resizing it I'm obviously going to loose most of the benefit of the wrap and blur as these won't be aligned.

With a series of transforms and masks I could probably get this setup to do what I want.. but this seems ridiculously cumbersome and imprecise (and probably won't work well at all..).. not to mention the added level of complication if trying to do this if combining multiple bits of footage in a single shot..

I feel like I'm going about this the wrong way.. what would be a more logical approach?

I hope I expressed my issue clearly!

Thanks

I do light wrap and edge blur in 2D, even when using a 3D scene. Render out each element you need edge control of as separate 3Drenders. Then apply light warp as you normally would in 2D.
Hope that helps.
