pop custom attributes April 25, 2012, 1:21 p.m.

Hi,

That example was cool in showing how to do this with a vopsop, but it still doesn't accumulate each frame. I know how to change the value of an attribute with the attributeCreate->writeValues section, but I don't know how to update that attribute each frame with a new value. Anybody have a solution for that?

thanks,

James

pop custom attributes April 23, 2012, 9:19 p.m.

Hi,

I'm simulating a smoke stack, and I have particles shooting upwards. When they reach a certain height I put them in a group via bounding box. I then assign a custom attribute “top_counter” in an effort to ramp up to the wind force that I'm applying to particles just outside of the smoke stack.

I know how to add an attribute, but I'm not sure how to update that attribute once it has been created. Can I update it with the same create attribute node, or do I need another node. I'm thinking it's some sort of channel function, that I don't know about but I'm just guessing at this point.

thanks,

James

points into curves April 23, 2012, 9:14 p.m.

Hi,

How do you take points and convert them into a curve? I have points strung together with a trail sop, but I don't think this is what I'm looking for. What am I doing wrong?

thanks,

James
