### Known Limitations

#### Lighting

- Mesh lights currently do not function
- PxrEnvDayLight, PxrPortalLight, and PxrAovLight are not supported
- <span style="color: #000000">We do not support the light handle operation to match the normal or shading attributes of a surface</span>

#### Interactive Rendering

- Interactive denoising is not available

#### Geometry

- NURBS and Implicits not supported

#### Shading

- For best performance, you should manually pre-convert your textures via [txmake](https://renderman.atlassian.net/wiki/spaces/REN20/pages/21561427) or use the Texture Manager
- The dynamic and uniform array node is not expected to work in Solaris

#### Expansion and plugins

- Only the built-in Integrators are supported
- Only the built-in Projection plugins are supported
- Only the built-in Display/Sample filters are supported (except stylized looks)

#### Image Tool

- crop tool and image selector is not supported

#### **OSX**

- M1 on OSX is not currently supported.    
You can run via Rosetta, but be warned, performance won't be as good until native support is added.
