Motion blur frails on AE reversed time layers

I tried using Motion Blur on an AE time-reversed layer and found it didn’t generate any motion blur. Once the layer’s time was reverted to normal (forward) motion blur worked as expected. A competitor’s product was able to motion blur a time reversed layer, though there may have been some errors in calculations.

I run across many instances when a 3D particle fx only gives desired results if its output’s time reversed.

Thanks, Kurt. Sounds like BCC Motion Blur requires precomping when applied to time-reversed layers in AE. I’ll file this to investigate.

Cheers,
