Hi! I have green screen footage that was chroma keyed, color corrected / graded, and exported in DaVinci Resolve (a video editor). To get it right, I matched my footage to a still image of a scene I made in Blender that’s using Cycles. And in DaVinci the footage is perfectly matched.
So I export that footage with a transparent background. The only thing not transparent is the person in the center. And the goal is to add this to the Blender scene so I can make it look more real by taking advantage of the Blender camera’s aperture, and the shadows that green screen footage can give when lighting is on it (shadows cast on walls, etc). I am using Cycles for all of this.
But when I load the footage in the scene, it blocks certain volumetric lights (but allows 1 in the center), and it doesn’t have the same color like when I exported it from DaVinci Resolve. The footage object is either too dark, or too bright, depending on the shading option I used when adding an Image As Plane (Principled BSDF, Shadeless, and Emit). Here’s an example:
Notice how the footage lets the volumetric lighting on the door pass through as it should, but not the windows on the left or right, even though the only object that should block it is what’s circled in green?
And how can I get my green screen object to be the color I made it as? I changed the color space of the object in the shading tab to RAW, and every other option, but none of these work as I’d expect.
I also tried adding extra lights to my footage in the scene, but that seems like a very inefficient way to do all this.
What is the most efficient way to go about this? Or is there some course that speaks about matching green screen shots to Blender scenes? All I’ve seen is surface level stuff that never deals with these sorts of problems.
