Five fixes in this commit... - the normals for nurbs surfaces still were calculated pointing wrong in some occasions - recoded ray-transp rendering to accept normals pointing any direction; it just counts how many times it passes a "glass" layer, and flips normals appropriate then. This means rendering will go fine on models without manually setting the normals. You can also move a camera inside a 'glass' object. - rendering of the inside part of glass now uses correct normal too... specularity happen on a solid glass inside now. - And an inside reflected mirror ray will keep bouncing inside glass Related to rendering localview: old convention to render localview, but with the lamps in the normal layers, has been restored. Please note; render happens based on active window. You *only* get a localview or 'unlocked layer' render when that 3d window is active = mouse in window.
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
