Requirements for particle systems

To make particles work with online rendering, every particle system has to be baked first. Particle system with non-baked cache won't work properly.

Preparing the scene

Particle system has to be baked to disk before sending to the Farm. This can be all easily done inside Blender:

  • select the particle emitter object;
  • go to the Particle panel;
  • scroll down to Cache section (expand, if required);
  • check Disk Cache option;
  • make sure to use Bake button:

Sending the job

Once the particle system is baked in cache, you can schedule your job, as usual. No additional tasks are required, all the cache files will be transferred to the farm along with the scene file.

In case of large particle systems transfer can take some time, especially for the first transfer. RayPump's differential transfer works with cache files as well, so following transfer (after some changes) should be much faster.


Despite your animation can be rendered on many nodes, baked particle system will behave as expected. Here's small sample scene rendered using RayPump with particle system:
