# Pixera v.2

With version 2.0.167 Pixera comes with a VIOSO-based calibration module and a completely renewed way to handle the inter-program communication. This avoids many of the obstacles in the past and enables a way more capable and streamlined workflow. 

In the following chapters we concentrate soley on this and future builds of Pixera.

{% hint style="info" %}
For Pixera versions < 2.0.167 please follow the instructions here: [pixera-v.1](https://docs.vioso.com/guide/mediaservers/avstumpfl/pixera-v.1 "mention")
{% endhint %}

## Licensing

The VIOSO licensing of Pixera 2 is handled by Pixera dongles on a per-projector basis:

In Pixera license information it is shown as VIOSO Product: VIOSO, x Outputs.&#x20;

Licensing for VIOSO outputs is solely handled by the Pixera Renderengine. For each PC that is rendering on projectors, the appropriate number of VIOSO Outputs must be licensed. Pixera Director or Pixera Creator PCs do not require dedicated VIOSO licenses.&#x20;

{% hint style="info" %}
Licensing of VIOSO for Pixera is solely handled by AV Stumpfl. VIOSO GmbH does not sell such licenses.
{% endhint %}

VWF files created by genuine VIOSO software of projectiontools software (sold by VIOSO GmbH) will work within Pixera without the requirement of VIOSO outputs on Pixera-side. This avoids double-licensing requirements (e.g. if existing VIOSO software of projectiontools software is used)

### Using old autocalibration module&#x20;

If a dongle contains "old" VIOSO licenses, it won't launch the new VIOSO 6-based calibrator but throw this warning:

<figure><img src="https://3901153090-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqQOJaA9kiXUCmPo5Lma3%2Fuploads%2FWYtMyel8uhZu1pTI1pRZ%2Fimage.png?alt=media&#x26;token=d803f901-0f46-4724-8393-f78ad0194458" alt=""><figcaption></figcaption></figure>

The easiest way to resolve is to update the dongle to enable the use of VIOSO.

As a fallback, an custom build of the autocalibration can be used, which is set in Settings / Calibration:

{% hint style="info" %}
Please contact <support@avstumpfl.com> to obtain a custom built calibrator that is compatible with Pixera 2 running old VIOSO licensing.

## VIOSO Installation

The autocalinbration software comes bundled with each Pixera installer.

## VIOSO Calibration modes

VIOSO 6 comes with two modes of operation: Free mode and Project mode (learn more about this here: [project-vs-freemode](https://docs.vioso.com/start/project-vs-freemode "mention").

Both modes are supported within Pixera 2, including 3D mapping features of free mode and 1-click recalibration automation for both modes.

We recommend to go with the Project Mode as default as it faciliates the setup by a great deal.
