Problems With Materials/Background When Doing Green Screen

[DuckJohnn]

Hi! I have two problems regarding the making of green screen scenes/renders.

1. I want the background to be completely green without any shading, but there is a dark vignette effect which ruins the renders, and the background removal in the video editor doesn’t work very well. The vignette effect can be removed by setting the “Post Process” setting to a lower setting, but I don’t want other things to change at the same time. Is there any other way to remove only the vignette effect on the scene?

2. All reflective things show a green screen on their surface, which I wouldn’t want. This can be prevented by changing the “Effects” setting to a lower setting, but I don’t want other things to change at the same time. I want it to reflect everything normally so that Green Screen doesn’t affect it. Is there any way to do this?

you could use the custom stencil “hack”. 4.x reference. https://www.youtube.com/watch?v=PiQ_JLJKi0M

stencil value 1 is green screen. value 2 is foreground elements. it works with 0 writes for foreground elements, but you have a lil more control if you mask them too.

unlit whatever material to block in the stencil value for the green.

and the exposure neutral pp material to puzzle it together

notes: you gotta enable the stencil pass in the project settings and use the default stencil write mode so the depth culling works.

and yes… you have to force the foreground elements into the stencil or the green screen blocker will overwrite everything with it’s value and you can’t go back to 0.
