Hello,

i want to create a fx layer for rendering that adds point attributes to a existing geometry. for example I get some fire wood geometry and I want to add a animated point attribute, that has some animated values to blend in a ember shader for lookdev.
Is it posssible to just write out this added attribute with it's primopath, so it can be layerd in later?

right now I get allways the complete data set for the geometry

thanks
Martin

if you are using SOP Modify check Perform Layer Break Before Import
if you are using just SOP Import insert Layer Break Before

and on import settings just disable what you don't want in your layer, like set Topology to None, in Attributes specify just your modified attribute, etc...
