I have a simple flow filling up a container, problem is I get an error in corona that it cant do geometry motion blur with changing topology. How can I get motion blur on the "Shape, 3D" geometry?
Thanks!
Corona isn't an officially supported renderer. Unfortunately your only option is to setup your flow in a way that ensures particle count doesn't change over time. One way of doing this is instead of birthing/deleting particles, just scale them to 0 when you don't want to see them.
With VRay you can switch the Mesh operator to instance mode, so it should render moblur correctly.
