Any object which the camera passes close by, when suitably fast, creates strange artefacts when "blur mode: motion vector" is activated for that model.
If I have a 3D model of text flying past camera (or camera flies past text), there are two or three frames with anomalous artefacts that appear, as if portions of the model's geometry is somehow not being properly positioned in relation to camera position.
The artefacts often feature a grainy appearance, and appear on both the RGB and the alpha layer.
My models are typically created in EI Modeller, exported as FACT. The same phenomenon however has occurred with Uber Shape objects generated within EI, and is not affected by whether the models have been deformed, are animated or static, or have had revised polys or effected by Dicer or any other plug-in, native or third party. Changing the camera's shutter angle only determines the length of some of the artefacts, though there appears little rhyme or reason with their positioning and size.
I have noticed this since I started using EI in 1997.
I have a demo project with a render and specific frames for anyone who wants to have a look. It's an easy phenomenon to replicate.
Setups have included:
Mac 9600 (OS9) (1997)
Mac Graphite G3 (OS9) (2000)
Mac Mirror-Front G3 (OSX) (2003)
Mac G5 (OSX) (2005) EIAS 8.0.0
