thanks for taking a look at this Aoktar, When I bring your resulting project once rendered into photoshop the image leans blue now rather than neutral. This seams to counter my test that was leaning green, but still does not generate a fairly neutral result. I am assuming i'll have to export out object buffers and compensate for the white balance shift, just seams like we could output a neutral render when using the same color temperature lights and assigning a white balance to those lights. Especially when everything in the scene is neutral.

Our white point is chosen to have an environment with an RGB color of (1, 1, 1) rendered as neutral grey. If you need D65 to be rendered as neutral grey you can change the white point in the imager settings to (0.754, 0.958, 1.000).
