    Hi All! 1_ I'd like to import an attribute created in SOP in the POPNET. I want to drive the particle emission rate based on this attribute. I've tried to use the point function in the constantrate parameter of the pop source. like: point( my sop node path, $PT, "myatt", 0) or point( my sop node path, $CUSTOM_ID, "myatt", 0) where custum_id is just a variable created in sop based on pt. there's something i am missing 2_how do i make the SOP attribute update every frame 3_ also i see in POPSource/Source Emission Attribute. The help doc says "When in surface mode, this point attribute will be used to vary the chance of any polygon from emitting polygons. Higher values will increase the relative chance of that polygon getting an emission." but it doesnt specify the values range. I supposed 0-1 (0-100% chance of emission). I did some test but seems to have no effect. thanks for helping!
