Hi I am processing blender file using python script passed in -P cmd argument
I am new to blender so I am not familiar with all bpy objects/properties. Can you help me with it? 1) How can I get current rendering tile and estimated time in cycles rendering engine? I know there is render_stats handler, and I even found function BlenderSession::get_progress in sources, but I am still puzzled how can I get this info from python script. 2) How can I get list of cameras available? 3) How can I setup active camera for rendering? 4) How can I get/set number of samples when rendering? And some question about GPU performance I was rendering first frame from classroom from blender demo (http://www.blender.org/wp-content/uploads/2015/04/classroom-200x107.png) I tested it on c4.large AWS virtual machine (2 cores of Intel Xeon E5-2666 v3) vs g2.8xlarge GPU vm(4 unspecified nvidia GPUs with 1,536 CUDA cores each) What puzzles me is that 2-core CPU vm renders 2x faster then 4-GPUs machine. On GPU I was using combined cuda device, and all GPUs was actually busy(nvidia-smi shows 99% utilization of all 4 GPUs) I understand that GPU/CPU are not very comparable, but results are still strange. Is there any specific conditions when GPU actually works faster then CPU? -- Regards, Andrey _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
