I hope that it would be possible to pack islands from texture projections from multiple objects...Packing Existing UV Texture Projections
You can now easily use the packing functionality from Unfold to pack islands from existing UV texture projections.
If the feature list is exhaustive, it's not verry interessant to upgrade. But anyway I bought a 2 years maintenance pack, and I do not want to learn another package, so I will stick to those outdated modeling tools. Sad...
Hopefully, new renderer are coming : octane, arion, redshift. But I do not wait for anything spectacular from Autodesk in this release (I wonder how they will market this new release... they have already done a video about camera sequence ).
Every new release since Autodesk bought Softimage, I'm just disappointed.
