A test build of Blender 2.75 was released this past week and it will be of interest to a lot of open-source designers and artists.

Blender 2.75 notably has added initial support for OpenCL on AMD Radeon GPUs with the Cycles Rendering. The AMD OpenCL support is coming as the Cycles compute kernels have finally been split into smaller kernels, so they now compile and work for AMD GPUs. However, the AMD OpenCL stack failing to work with transparent shadows due to a compiler bug. The AMD OpenCL improvements for Blender was work led by AMD that we previously covered on Phoronix.

Blender 2.75 Cycles also has support for Light Portals and contains several performance and memory optimizations. Other Blender 2.75 work includes real-time visualization of the stereoscopic effect, rendering of multiple views, compositor and sequencer improvements, and numerous other additions. There's also a new OpenGL Preview option for Blender to save your work as an OpenGL preview of the animation.

More details on the current Blender 2.75 work in development can be found via the tentative release notes. Those wishing to try out the current test build of Blender 2.75 can find it at
