  • Spherical Projection onto area lights?

    Spherical Projection onto Area light and diffuse doesn't look right, reflection looks fine though.

    So I have a HDR with Spherical Projection onto a set, I'm then using that projection on a few VRay Area lights and while the reflection looks fine the diffuse doesn't match what a dome light would, I guess this is expected though?

    Could you give us more details on what exactly are you trying to achieve. It would be helpful to share some screenshots or your test scene.

      We lighted a whole feature film like that but the lights weren't visible to camera so I never noticed that it was off. Does it look right if you map the texture onto a plane in the same place as the area light?

        That's a good idea, I'll do a check when I have some more time
        so I'm doing a direct comparison between a dome light and Area lights my guess is that the rays of a dome light will all converge in but area lights will spread outward, in that case it makes sense that the diffuse will appear different
