I currently have a simple scene in blender consisting of a particle emitter with thin rectangular prisms as particles. They have a pretty fast speed, and it's causing some terrible looking artifacts in the final renders.
I've tried this with standard vector blur with compositing nodes in blender:
And I've tried this with the basic motion blur option available in Cycles:
This looks really great as a still image, but as soon as I actually go in and press the "animate" button instead of still render, it starts to fall apart.
And in my current revision, the Motion blur setting makes frames horribly messy and doesn't seem to know where the object is going. Blurs are curved instead of linear like in the still image.
I've never had a problem like this before where the animation view looked different than the still image view. What's going on, and how can I fix it?
