# Smoke, fire and atmospheric rendering

#### Smoke, fire and atmospheric rendering 

V-Nova PresenZ does support Smoke, Fire, atmospheric and more broadly "volumetric" rendering from Maya Arnold. But it is important to remember that a volume that takes up a large space will greatly increase the number of points and the amount of data in the scene. So this will take up more blocks in the render. As such, you should limit the amount of space used for atmospheric volumes by using the aiAtmosphereVolume shader on a geometry. As seen below

You should avoid the atmosphere attribute inside Arnold, as this will create points throughout the scene and will affect your renders, as mentioned. It will also create issues where you will need to render inside the Zone Of View.

When rendering any volume, it is important to limit the number of effective Lights and improve the samples of the render inside of Arnold

* Here is a simple look at render settings that will work for testing

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.v-nova.com/technologies/v-nova.presenz/v-nova-presenz-documentation/smoke-fire-and-atmospheric-rendering.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
