[@AhmedKhaledFX]

Brilliant , Thanks Alex

[@MMMMeeeeMMMM]

This is a cool technique! Thanks

[@GaelLendoiro]

Thanks!

[@ocdvfx]

woahhh, very cool

[@davidcatalano7426]

unfortunately nuke give us only the normal in "WorldSpace" and for the Fresnel we need normal in "Camera Space".. We have to convert the normal using the Camera World matrix to have the perfect fresnel

[@DougHogan]

You can actually convert World space to camera space with the camera data in Nuke!

Hey Doug. I've actually never had the need to do that. I'd be curious to know how to though.

@@alexvillabonshufle normals into rgb, add colormatrix, conect camera matrix to colormatrix (control drag) check invert in colormatrix, and now you have camera space normals
