Usage Examples
The example we will use for both session involves rendering an animation file file.blend
blender -b file.blend -E CYCLES -s 10 -e 500 -t 2 -a
- -E CYCLES Use the “Cycles Render” engine. For a list of available render engines, run blender -E help.
- -s 10 -e 500 Set the start frame to 10 and the end frame to 500.
- -t 2 Use only two threads.

Batch Job
The batch script would look like this for the same example:
#!/bin/bash #SBATCH -J jobname # Job name, you can change it to whatever you want #SBATCH -n 2 # Number of cores #SBATCH -o %N.%j.out # Standard output will be written here #SBATCH -e %N.%j.err # Standard error will be written here #SBATCH --gres=gpu # use the GPU resource not the CPU #SBATCH -p gpu # Slurm partition, where you want the job to be queued #SBATCH -t=00:40:00 # Run for 40 minutes module load blender/2.83.2 blender -b file.blend -E CYCLES -s 10 -e 500 -t 2 -a
