Re: vd16 and alpha channels PS -> Nuke
Troy Sobotka <troy.s...@...>
The predivide has to happen prior to TRC inversion.
If the issue is alpha / luminance based, the read node has a “Premultiplied” radio box.
This should take the associated alpha image, predivide it, apply the inverted TRC / transfer curve, then apply the alpha again.
If you attempt to do a similar thing from within a Nuke node chain, the error would already be baked into the data buffer.
