Instanced object constantly change

[antonforze]

I have a problem with position of instanced object that constantly changed whenever i changed the geometry surface or the boundary spline area of chaos scatter, does anybody have issue like me? thankyou

If you edit distribution surface, then distributed instances' positions will inevitably change, there's no way around this, it's how Corona scatter works.

thanks for your reply,

is there any tips to use chaos scatter but the instanced object consistent? in my case there is some feedback that the surface of scatter need to be edited (like adjust the height of the contour) but the instanced object still in the place (just the height change)

You can try to enable temporal consistency in scattering rollout, but i doubt if will help if you're modifying distribution object. Can you tell why having fixated scattered instances positions is so important in your case?

I was also thinking that temporal consistency could help here. And I am also interested in learning more about the scene itself - what exactly are you rendering and why do you have these specific requirements?
