Hi Everyone
It's a basic particle and one color node in that color ramp lookup express is $LIFE
and Alpha ramp lookup express is $LIFE and final copy stamping with sphere in view port it's getting color and alpha but while rendering that it's not getting alpha /opacity it's getting only color value.

i switch on point color and opacity in shader.
Also it tried without copy node only particle and color node that also not working.

Hi,

You have to use the VEX Layered Surface shader which reads the colour (Cd) & alpha (Alpha) attributes directly and you should get what you expect.

Cheers!

Also, make sure that in the Copy SOP- Attribute Tab, that you have “Use Template Point Attributes” toggled on.
