Arnold Utils and Deep one pixel smaller than the beauty.

Recommended Posts

Rendering utils unpremultiplied and unfiltered. Rendering beauty premultiplied and filtered from Arnold and we find that the utils (and Deep) are coming out one pixel smaller than the beauty. I woul have expected the antialiasing to smooth inwards - or in otherwords for utils to ecompass the full area of the beauty.

These are shots with minimal motion blur. Utils are rendered 32 bit, beauty 16bit, everything is zip1 scanline linear ACESCG exrs.

Our usual comp fix is to dilate the utilities out a bit, but it can introduce edge issues this way.
