## **Inputs**

---

**mtl** - Connection to apply a material to the V-Ray Volume Grid. It is necessary for the Volume Grid to be in [Mesh mode](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625197), the Surface channel needs to be set and an appropriate Isosurface Level must be chosen from this section.

**dsp** -  When [Displacement](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625365) is enabled it will be based on the values of the connected texture map. 

**tr** - The smoke opacity will be based on the values of the connected texture map if **Based on** is set to **Texture**.

**dif** - The smoke color will be based on the values of the connected texture map if **Based on** is set to **Texture**.


## **Volume Grid Options**

---

The following options are provided for modifying the appearance and rendering of the volume grid. For more information, see the [Volumetric Grid Properties](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110626618) page.

- [Input tab](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625191) - Provides controls for multiple frame input, timing of frames, and blending/smoothing of frames.
- [Preview tab](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625199) - Provides controls for how the volume grid effect is displayed in the viewport.
- [Rendering tab](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625197) - Provides controls for how the volume grid effect is rendered.
- [Fire tab](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625195) - Provides volumetric shader controls for the emissive color (fire) and the light emitted by the volume grid.
- [Smoke tab](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625193) - Provides volumetric shader controls for the diffuse (smoke) color and opacity.
