Yes, we support Karma!

Yes, and this is one of the most powerful ways to use the farm. You can submit your entire pipeline in a single click, from simulation caching through to final Karma renders, and our system handles the dependency order automatically.

Just chain your nodes the way you normally would: connect your File Cache or simulation nodes first, then your Karma render node, and attach our HDA to the end of the chain. The farm will run your simulation, wait for it to complete, and then start rendering without any manual intervention.

You can submit up to 100 tasks simultaneously in one submission, making it practical to cache and render an entire shot or sequence in one go.

Yes. Our Drop & Render HDA supports submissions from any Houdini network context:

• LOP networks (Solaris): The primary context for Karma, fully optimised for USD-based workflows and rendering with Husk.

• ROP networks: Also supported for Karma render setups outside of Solaris.

• SOP networks: Ideal for geometry processing or simulation caching tasks that feed into your Karma pipeline.

Just connect the HDA to your chosen node and submit with a single click. The HDA adapts to your graph structure and fits into the workflow you already have without requiring any restructuring.

No. Drop & Render is an official SideFX partner, and all Houdini and Karma licensing on the farm is covered by us. You do not need to purchase additional render node licenses or worry about license counts when scaling across hundreds of machines.

You only need your own local Houdini license for working in the application, which you already have. Everything on the farm side is fully covered by Drop & Render.

Yes, both Karma CPU and Karma XPU are fully supported. Our farm hardware is equipped with the latest CPUs and GPUs, so whichever mode your project is set up for will run correctly without any changes to your scene.

Karma XPU in particular benefits enormously from the farm. Since XPU is GPU-accelerated, having 100 to 200 GPUs working on your job simultaneously means render times that simply are not achievable on a local workstation. You submit the same way regardless of mode, and our system handles the rest.

Yes, full native support for Solaris and USD workflows is included. You connect our HDA directly to your Karma render node inside the LOP network, such as a usdrender_rop, and submit with a single click.

We offer two Karma render workflow modes:

• USD conversion per frame: Each frame is converted to USD and rendered immediately. This is typically faster to submit and avoids long upfront conversion times.

• USD convert all frames first: All frames are converted to USD on our farm before rendering begins. This is more stable for complex scenes where you need full control over USD outputs.

In both cases, final rendering is handled by Husk, SideFX's native USD renderer, fully managed by our system with no manual setup required.
