New Features
Trapcode 3D Stroke version 2.5 has updates to the render engine and new support for a variety of host applications. A new Preset menu has been added to make it easier to create simple stroke animations.
Broad Application Support
Trapcode 3D Stroke has been modified to run properly on a variety of host applications, including Adobe After Effects, Adobe Premiere Pro, Apple Final Cut Pro, Apple Motion, Avid Xpress Pro and Media Composer.

3D Stroke Render Engine
3D Stroke now supports full 32-bit floating-point rendering for generating animated lines with the highest quality output. The output of the plug-in will be the same in any render mode.

New Presets
3D Stroke now features a series of 40 preset shapes for generating outlines or swirling strokes. The mask option is still available in After Effects so that you can use the internal masks created in After Effects. This option appears in all of the supported hosts. In hosts other than After Effects, Presets are the ONLY way to create a stroke effect.
The new presets are simply SVG files that are loaded from disk when selected in the menu. Here is the new preset menu.
Here is a gallery showing the various preset shapes.
