Welcome to disguise Insights, a series of tutorials and knowledge focusing on different elements of the disguise production toolkit. The second in the series delves into content templates.

Why a content template?

A content template is a 2D representation of a 3D object either rendered from a UV map or from an image editor like Photoshop and normally content templates are generated in the pre-production phase.

We use content templates as they provide an animator with a canvas to draw, colour and fill from a video editor, such as After Effects. Video content can then be encoded and formatted for playback in the disguise server.

How to create a content template

Now we have explained why we use content templates, we will delve into how to create a content template…

Before you get started in creating a content template, a summary of modelling and texturing is required. In an object editor, such as Blender, you can generate a 3D object and UV map. A UV map comprises vertices, edges and faces in UVW space, and every selection correlates to a 3D object in XYZ space and a 3D object is unwrapped to generate a UV map. For example, a dome may be unwrapped to form a hemisphere, or a cuboid maybe unwrapped to form a net.

A key principle to consider is the relationship between a UV map and content template. A UV map is constructed from vectors and a content template is constructed from pixels. Vector space is normalised 0-1 and pixel space is variable.

Designing a content template

For projection the UV map is curvilinear and for LED the UV map is rectilinear. The content template is limited to the hardware output prompting the question: what other content workflows are available to animators?

After Effects enables the transfer of video content between compositions with external plugins, such as Youveelizer.

More tips and tricks are available when creating a content template. For example, render the template to TIF format to negate compression artefacts, render the template to SVG format to enable vector workflows, label the template for the animator, and save the template’s resolution in the file name.
