MBOX® USER MANUAL
Projected Mapping
The rst two steps are to set up the additional universe of control (via Art-Net or to sACN), and to edit the base
information in the conguration.
Step 1. Click on the Image Remapping tab, then double-click on the “0” in the Universes area - the default universe
0 - and type in a new number (this tutorial uses universe 16) that is not one of the current control universes
for the Mbox server. Press [return] to accept the change.
Step 2. Next, if there is no conguration already in the conguration list, click on the Add button at the top right of
the window and select Add Conguration from the menu. Don’t change the Global Texture Position Scale
setting.
There should be one entry in the conguration list “[001] No Name {720, 480}”): this is the rst conguration and has
an index of 001. Mbox Designer allows up to 255 congurations (though this tutorial will only have two), with each
having its own set of screen objects. Every conguration can be unique or can have the same screen objects but
with different image remapping positioning, image scaling, or controls. All congurations get saved into the same
MultiScreenData.plist le and a layer can use the Image Remap parameter to enable remapping for that layer and to
select a conguration by index value (between 1 and 255).
Step 3. Click on the conguration ([001]) in the list at the left of the window and notice that the window changes from
showing the Global Scale setting to showing the conguration’s settings: specically Texture Width & Height
and Display Width & Height. Edit those values to be 900 x 900 and 1920 x 1080 respectively, make sure to
press [tab] or [return] after each entry. Give the conguration a new name, “Projected Mapping”, as well.
The texture width and height dene the size of the content to be used with the conguration. This needs to be pre-set to
provide the correct pixel-accurate positioning relationships between the content and the remapping.
Note: Pre-setting a conguration’s texture size doesn’t mean that content of a different size cannot be used, however
its origin will be offset from the origin of the conguration. The layer’s X and Y position parameters can be used to affect
this, but that placement may not be pixel-accurate. Therefore in some cases it may be necessary to create more than
one nearly identical conguration, with only a different texture width and/or height.
