Camera FOV Based Projection Painting
Projection painting using an imported FBX camera.
If you import a FBX camera and a texture with matching resolution you can manually try and position the projection texture but this is not perfect.
You should have an option when projection painting to scale texture to camera field of view perfectly.
Ideally you could then "apply projection" rather than having to paint the entire screen.
This would be greatly helpful for photogrammetry or VFX work.
