Blender 2.45

Blender 是一套整合型應用程式，可用來建立各種 2D 與 3D 內容。Blender 在單一套件中提供了廣泛的建模、材質、燈光、動畫與影片後製功能。透過其開放式架構，Blender 具備跨平台互通性、可擴充性、極小的佔用空間，以及緊密整合的工作流程。Blender 是全球最受歡迎的開源 3D 繪圖應用程式之一。

主要特色：

• 完整整合的創作套件，提供建立 3D 內容所需的各種必備工具，包括建模、UV 貼圖、材質、骨架綁定、蒙皮、動畫、粒子與其他模擬、腳本、算圖、合成、後製，以及遊戲創作；
• 跨平台，所有平台皆使用 OpenGL 統一圖形介面，可直接用於所有版本的 Windows（98、NT、2000、XP）、Linux、OS X、FreeBSD、Irix、Sun 及眾多其他作業系統；
• 高品質的 3D 架構，實現快速且高效的創作工作流程；
• 每個版本在全球有超過 200,000 次下載（使用者）；
• 使用者社群支援，可透過 http://BlenderArtists.org 的論壇提問、解答與評論，以及 http://BlenderNation.com 的新聞服務；
• 執行檔體積小，易於散佈。

* SSS now works with panorama render.
* Removed artifacts with negative lights when using SSS
* Disabled SSS for preview rendering, so it didn't slow down other preview render at all.
* Fixed error in "Transform Constraint" with planar constraints when the plane was perpendicular to the viewport.
* Fixed the vector blur error in "Ztransp" that produce black lines (on edges) appeared, which didn't get blurred away.
* Fixed an error in the Particle System that cause bad results for command line renders, especially when rendering first frame of animation.
* Fixed Verse crashing in 64 bits Linux.
* Math node now has reflective behavior.
* Multires meshes with UV's and vertex colors would crash in many cases.
* Importing 3DS files with lamps failed.
* DXF Importer updated, includes stable support for 3d objects and blocks hierarchy.
* FBX Exporter updated, includes fixes for better compatibility with other applications and support for exporting animation with armature deformed meshes and objects.
* Collada support updated for better armature support.
* Bundled python modules were not included in 2.44 by accident, making some scripts fail in 2.44 that worked in 2.43 (Windows Only, when Python was not installed)
* Fixed bug in the shadow calculation that cause errors where specularity would ignore shadows.
* Changes to the insert keyframes method for determining when to replace existing keyframes with new ones. Now, it shouldn't create so many keyframes stacked on top of each other.
* Blender would crash if boolean operations were done on objects wich resulted in an empty mesh. This was due to accessing invalid memory.
* Remove the options "make local" in the Outliner. It didnt work properly and produced errors in the linked data.
* Edgesplit crashes are fixed, the problem was that "bridge" vertices (which connect two or more faces that don't share edges) were not being included in the maximum final vertex count calculation (used for memory allocation, hence the crashes).
* Fixed Multires Editmode memory leak. Typo in Multires Editmode integration meant that far too much memory was getting allocated for a pointer array (more than 10 times as much).
