The Blender 2.43 release is getting closer everyday, and even with the clock counting down to release, huge advancements are being made to the Blender code. This time, Ton has done an image refactor (committed to the CVS Dec. 20th) and Brecht has given us the much asked for Multiple UVs and vertex colors (committed to the CVS Dec. 21st)!
From the Image Refactor documentation:
With the Blender Compositing and Pass Render features, the need for a more advanced imaging system in Blender was evident. Many much wanted features now are available, such as:
- MultiLayer image read/write, and integrated in all editors
- Flipbook playback for compositing, sequences or movie files
- Painting in Image Sequences, in MultiLayer images, and integrated with Compositor
- Repacking Images
- Procedural Images
From the Multiple UV commit:
Added names to UV and vertex color layers, and display them as a list.
Added support for multiple UVs in the render engine. This also involved
changing the way faces are stored, to allow data to be added optionally
per 256 faces, same as the existing system for vertices.
A UV layer can be specified in the Map Input panel and the Geometry node
by name. Leaving this field blank will default to the active UV layer.
Also added sharing of face selection and hiding between UV layers, and at
the same time improved syncing with editmode selection and hiding.
This was a great deal of work, so to truly appreciate it you should read the entire documentation page of the image refactor as well as pick up a CVS build from graphicall if you want to see these features in action!
