Foundry Nuke Known Issues

Auto-Alpha checkbox in Nuke Read Node: Nuke8.0v1 introduced an issue. The issue is fixed in Nuke8.0v6.
Images of the form R,G,B,0 (zero in alpha channel or RGB only with no alpha channel) normally require for many of our plug-ins when color correction is involved to be R,G,B,1.0 (have a filled alpha channel). This is so as we need to assume Nuke is premulted and we must handle color operations with semi-transparent alpha in non-premult space. Multiplying by 0 (zero) creates a transparent 0,0,0,0 image.  Solution if the problem occurs is either to upgrade Nuke or use before the effect a Channel operation that fills the alpha with 1.0.
