frontal projection Tweet

[christiaan]

Hey there,
I have searched the forum for some more insight into frontal projection, I need it for some vfx.
I have a background and need the floor to be projected to show in the reflection of an object I use in the scene.
With a lot of matching I get somewhere with the perspective projection but it is not 100% accurate and it takes a lot of tweaking.
Is there a way faster than this...

Hi,
use an Environment node in Visible mode, and change the Projection of the ImageTexture node to Osl Projection, then chose cameraEnvProjOSL.osl, from presets:

Thanks, that almost was the problem.
In the screenshot I added, I put a plane on the floor and used the same settings as you said in the shader so it could work as geo to interact with.
But as you can see when I render there are borders which are not the desired outcome.
