blender-util is a repo of random blender code to make life easier.

render.sh - start a render from the commandline without opening the GUI

render.sh -b $BLENDER_FILE -E $ENGINE -s $START_FRAME -e $END_FRAME \
    -t $THREADS -o $OUTPUT_FILE -a

This will render frames 0-1000 using 12 threads and output the frames to video_0000.png, video_0001.png, etc.

render.sh -b $BLENDER_FILE -E CYCLES -s 0 -e 1000 -t 12 -o //video_ -a

convert.sh - convert non-blender 3D format files to and from .blender format

convert.sh $INPUT_FILE $OUTPUT_FILE

This will convert input.obj to output.blender

convert.sh input.obj output.blender
