Hi,

I have a scattered grid with 100 points with Cd = {0,0,0}. These points born by color (attribute transfer with an animated sphere with Cd = {1,1,1} and Delete with the expression @Cd > 0.1).

I would like to know if its possible to get the birthframe number: For example, when one point born at frame 50 (Cd = 0 to Cd = 1) I need an attribute for this point that must be 50. If the next point born at 61, the attribute of this new point would be 61.

Do you know how can I get this number for each point?

Thanks!!

Use a popnet particle system. Scatter does not manage any particle attributes such as birth age etc… Scatter is often used as the initial point set for a particle system. just birth all points on frame #1 and your points will inherit all particle attributes.
