This means the diffuse and specular shaders don't use the normal for hair (which is actually undefined, a hair is micro cylinder) but it uses the tangent vector (vector in direction of hair). For Diffuse, it computes a fake normal now, representing the optimal hair normal pointing towards the light. All current builtin shaders work with this, including ramps. For Specular, it uses another formula to remap dot products for all lines that now use the tangent vector instead of the normal: dot = vector * tangent dot = sqrt(1.0 - dot*dot) Gives better results than using the 'fake' normal for diffuse. Officially (according the papers) this could be used for diffuse too, but then hair becomes very flat. Now you can control the flatness easily with ramps or using Oren-Nayer for example. Example image (disappears in some weeks) http://www.blender.org/bf/rt9.jpg - Added new texture channel "Strand" to apply textures on hairs over the length of hair (1 dimensional). Orco now gives 1 fixed coordinate for the entire hair, based on where it starts. Note; UV doesn't work yet. Nor vertexcolor. http://www.blender.org/bf/rt10.jpg
Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/docs/get_involved.html Community: http://www.blender3d.org/Community/ Main blender development site: http://www.blender.org/ The Blender project homepage: http://projects.blender.org/projects/bf-blender/ Documentation: http://www.blender.org/modules.php?op=modload&name=documentation&file=index Bug tracker: http://projects.blender.org/tracker/?atid=125&group_id=9&func=browse Feature request tracker: http://projects.blender.org/tracker/?atid=128&group_id=9&func=browse
