- Links now can be made between any socket type. The nodes recognize amount of channels, and will convert types if needed. Conversions from RGBA to 1 channel will use the 'RGB to BW' formula. Also note that conversions only happen when required. So you can blur an alpha channel, filter it, and put this in a 1-channel socket without any conversion to happen, which saves memory & cpu time. http://www.blender.org/bf/rt.jpg The blur nodes don't accept Vector input yet... But filter does. - RGB Curve Nodes now have the premultiply option resored, 2 x faster - Fixed some confusing code in Node Group handling... much stabler now
