4. Multiboxing

Using a multibox instead of increasing the size of the ZOV is a good choice to avoid some key issues you might experience.

Having a larger ZOV means that there will be a bigger occlusion factor (parallax). This generates a larger file size since there is more information to capture. Depending on the specs of your VR machine this might cause performance issues.

For the multiboxing, multiple ZOV’s will have to be rendered. In the PresenZ plugin you can set the offset of each ZOV with respect to the central one.

Warning

Each ZOV has to be the same resolution and size!

In the image above there are three different PresenZ settings, one for each zone of view. It’s mandatory to render all the zones of view separately. After the rendering and the merge, you will have three prz files, one for each ZOV.

4.1. Merging your .PRZ images into a multibox

Once you have rendered the several .PRZ images for each multibox, you can merge them into one file using the PresenZ Dashboard. More information on how to do this can be found in the PresenZ Dashboard section
