Corona Scatter can not with Spline

Corona Scatter can not with Spline.Who can help me?

Hi,
You need to select 1D - on splines mode in scattering rollout. See atachment.

I do this,but it’s not useful.But the weird thing is that there is no problem with the same software on other PC。

Are you saying that exactly the same setup works on one PC, but not on another? Can you show Corona scatter screenshot where it doesn’t work?

If you want to scatter objects on the surface of a spline shape, as if it was a polygon, you have to make sure it is a closed spline.
