# Docs

- [Introduction](/docs): Native C++/CUDA operators for TouchDesigner. Real-time rendering and simulation without leaving the network editor.

- **Getting started**
- [Installation](/docs/getting-started/installation): Get a NativeOps plugin loading in TouchDesigner in under five minutes.
- [Requirements](/docs/getting-started/requirements): Supported TouchDesigner builds, GPUs, and drivers.
- [Licensing](/docs/getting-started/licensing): How NativeOps seats work — what a license covers, and what it doesn't.
- [Activation](/docs/getting-started/activation): Bind your license key to a machine — online in seconds, or offline for air-gapped rigs.

- **Plugins**
- Photon RTXPT
  - [Overview](/docs/photon-rtxpt): Real-time path tracing inside TouchDesigner, built on NVIDIA's RTX Path Tracing SDK.
  - [Operators](/docs/photon-rtxpt/operators): The Photon RTXPT operator set and how a scene assembles.
  - [Parameter reference](/docs/photon-rtxpt/parameters): Every Photon RTXPT parameter, with types, ranges, and defaults.
  - [Materials](/docs/photon-rtxpt/materials): Principled, emission, and glass materials — bound by path, driven by TOPs.
  - [Lights](/docs/photon-rtxpt/lights): Area, sun, dome, and mesh lights in physical units.
- Photon OVRTX
  - [Overview](/docs/photon-ovrtx): The Photon front end on the ovrtx backend — same scene semantics, tuned for interactive previz.
  - [Operators](/docs/photon-ovrtx/operators): The shared Photon operator set, as seen from the OVRTX engine.
  - [Parameter reference](/docs/photon-ovrtx/parameters): OVRTX-specific parameters alongside the shared Photon set.
  - [Materials](/docs/photon-ovrtx/materials): The shared Photon material models, and how OVRTX approximates them.
  - [Lights](/docs/photon-ovrtx/lights): Photon lights under the OVRTX engine — same units, different sampling.
- Matter
  - [Overview](/docs/matter): GPU rigid bodies, fluids, and cloth as one operator suite — eight operators, one solver clock.
  - [Operators](/docs/matter/operators): The eight Matter operators and the network shape they expect.
  - [Parameter reference](/docs/matter/parameters): The Matter parameter surface — solver first, per-body pages after.
  - [Coupling](/docs/matter/coupling): How rigid bodies, fluid, and cloth exchange forces inside a single substep.
- Aura
  - [Overview](/docs/aura): Real-time 2D global illumination for layered scenes — emitters, occluders, and bounce in a single TOP.
  - [Inputs](/docs/aura/inputs): The Aura layer contract — what each input plug expects and what it does with it.
  - [Parameter reference](/docs/aura/parameters): The Aura parameter surface — light transport, quality, and output.

- **Resources**
- Guides
  - [Guides](/docs/guides): Task-oriented walkthroughs — from empty network to running show.
  - [Your first path-traced frame](/docs/guides/first-render): Empty network to a denoised Photon RTXPT render in ten minutes.
  - [Licensing a render farm](/docs/guides/render-farm-licensing): Offline activation at rack scale — seats on headless nodes without a browser in sight.
- Troubleshooting
  - [Troubleshooting](/docs/troubleshooting): When an operator won't load, won't license, or won't cook — start here.
  - [GPU requirements](/docs/troubleshooting/gpu-requirements): The load-time hardware checks, in the order they run, and what each failure means.
  - [Drivers](/docs/troubleshooting/drivers): Known-bad ranges, the clean-install ritual, and why Studio drivers exist.
  - [Activation problems](/docs/troubleshooting/activation-problems): Key rejected, seat conflicts, offline files that won't take — the failure modes and their fixes.
- [Changelog](/docs/changelog): Releases across every plugin — placeholder entries until the first public builds.
