[Openexr-devel] transparent samples

[Gunter Sprenger]

Please advice on the correct method to put multiple transparency samples into a pixel in deep-exr. At tile borders

of a rendered image occasionally there are multiple samples at the same depth with the same rgba color.

Both exrdisplay and nuke show a slightly darker (i.e. less transparent) grid pattern because of the multiple samples

at tile borders.

This could also happen in adaptive sampling, here it would look much worse I guess (i.e. having different numbers

of transparency samples in the pixels).

The samples have fractional coordinate values, they are rounded to integral values for deep-exr.

Thanks
