# Quick tips

**Quick tips**

Some miscellaneous helpful tips for V-Nova PresenZ

* **Camera:** Make sure your camera is visible to V-Nova PresenZ; don’t put it on a hidden layer. Also, be sure the camera is not locked and has its parameters editable.
* **Quick tests:** Remember that you can change the renderer resolution of V-Nova PresenZ to perform quick tests. Don’t be afraid to use 1200x800 or even 720x480 to make quick test renders. It can be combined with Draft Mode.
* **Command line merger/Prz\_Maker:** When using the merger.exe to merge your rendered files ( .przRenders ) into a .PRZ file for the Viewer. Make sure that the directory of the merger is your current directory, so it can find the necessary files.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.v-nova.com/technologies/v-nova.presenz/v-nova-presenz-documentation/quick-tips.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
