I’m learning UE for linear media rendering and I have a question about motion blur effect.
Below is a sample picture from a project of mine. Take the example of the grass blades, I’ve noticed the motion blur effect has a very homogeneous look. It’s like the shutter goes from completely closed to completely open in an instant, and stays open for the duration of the frame, then closes instantly again.
This makes the motion blur effect very edgy and sharp, I want it to look softer like on the right. But playing with motion blur intensity in post processing volume only changes the length of the motion trail and it stays sharp regardless.
Other offline renderers from traditional DCC softwares offer options like shutter efficiency and what it does is making the camera shutter take time to fully open and close thus reduce the weight of both the beginning and the end of all the sub-steps of a blurred frame (but not eliminate them all together) and make the middle of the frame stand out thus making the motion blur softer.
So my question is how do I achieve this result in UE (I’m using 5.5.3 as of now)?
