Regular rendering now works tiled, and supports save buffers to save memory during render and cache render results. Brick texture node by Thomas. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures#Brick_Texture Image texture Blended Box Mapping. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures#Image_Texture http://mango.blender.org/production/blended_box/ Various bug fixes by Sergey and Campbell. * Fix for reading freed memory in some node setups. * Fix incorrect memory read when synchronizing mesh motion. * Fix crash appearing when direct light usage is different on different layers. * Fix for vector pass gives wrong result in some circumstances. * Fix for wrong resolution used for rendering Render Layer node. * Option to cancel rendering when doing initial synchronization. * No more texture limit when using CPU render. * Many fixes for new tiled rendering.
