== Shader nodes == * Geometry node: Front/back output This is used as a mask for determining whether you're looking at the front side or back side of a mesh, useful for blending materials, my practical need was giving different materials to the pages of a magazine: http://mke3.net/blender/etc/frontback-h264.mov Give 1.0 if it's the front side, and 0.0 if it's the back side. * Extended material node This is the same as the material node, but gives more available inputs and outputs, (basically just connecting up more of ShadeInput and ShadeResult to the node). I didn't want to add it to the normal simple Material node since you don't always need all that stuff, and it would make the node huge, but when you do need it, it's nice to have it. == Comp nodes == * Invert node Inverting is something that happens all the time in a node setup, and this makes it easier. It's been possible to invert previously by adding a mix node and subtracting the input from 1.0, but it's not the best way of doing it. This node: - makes it a lot faster to set up, rather than all the clicking required with the mix node - is a lot more usable amidst a complex comp setup, when you're looking at a node tree, it's very helpful to be able to see at a glance what's going on. Using subtract for inverting is easily mixed up with other nodes in which you are actually subtracting, not inverting, and looks very similar to all the other mix nodes that usually litter a comp tree. - has options to invert the RGB channels, the Alpha channel, or both. This saves adding lots of extra nodes (separate RGBA, subtract, set alpha) when you want to do something simple like invert an alpha channel. I'd like to add this option to other nodes too. There's also a shader node version too. * Also a few fixes that I committed ages ago, but seems to have been overwritten in Bob's node refactor: - adding new compbufs to the set alpha and alphaover nodes when you have only one noodle connected to the lower input - making the fac value on RGB curves still work when there's nothing connected to it
