Usage & Performance Tips

Here a few usage and performance tips while working with Plexus.

Facets or Triangulation

Facets are created by the geometry objects or imported from the OBJ files i.e. they are created only when the geometry is initially created or imported. You can apply noise to the vertices and the Facets are not recalculated. Also, you can apply noise to the facets itself, i.e. vertices remain at the same place but the facet properties like position and color can be altered without changing any vertices. The Facets have to be rendered using a Facets Render Object.

Triangulation Object triangulates all the vertices every frame. No matter how much noise is applied to the vertices, just before rendering all the vertices are triangulated. Its almost like mesh reconstruction. Facets Render Object just renders existing facets while Triangulation Object actively recalculates the triangulation for every frame. So there is no way to add noise/effectors to those triangles created by triangulation object. They are only created just before rendering in the final stage.

Null Objects

For After Effects CC 2015 or Later: Starting Plexus 3, if you’re using Null Objects in Layers Object there is no performance penalty. In fact, it is recommended to use Nulls over point lights because of their flexibility. You can continue using Point Lights, but they’re no longer recommended.

For Older AE versions of After Effects (CC 2014 and Before): Older versions of AE don’t have the necessary APIs introduced in CC 2015 so, point lights are preferred to Null Objects when working with Plexus Layers Object.

OBJ Performance

OpenGL Rendering

OpenGL Rendering

You need a capable Graphics card that supports atleast OpenGL 3.2. OpenGL rendering is required when using Unified Rendering. Unified Rendering is required to add Depth of Field or Motion Blur effects in Plexus.

Only Mac OS X 10.8 or higher support OpenGL 3.2. On Windows, it depends on your Graphics card vendor. Also, make sure to update your graphics drivers.

Textured Sprites

Plexus does warn if the Sprites are exorbitantly huge and take up so much memory, but there is no hard limit it depends on the render load. Generally, anything below 256px is recommended for good performance.

Unified Rendering Freezes After Effects

If you try turning on ‘Unified Rendering’ and After Effects freezes/crashes, then most likely you’re running outdated OpenGL/Video drivers. To fix this issue, download the latest drivers directly from your vendor’s website (ATI/Nvidia). For Nvidia cards, download directly from

For ATI cards, download directly from

For Intel cards, download directly from
